Cancer survivors ofttimes ask their health intendance providers if food choices, physical activity, and dietary supplements could ameliorate their quality of life and survival. But they also look to news reports and studies for this kind of information. Before making whatsoever changes to your nutrition or activity levels, information technology is important to make sure the information is based on facts from multiple research studies.

It usually takes more ane study to prove a method works. Virtually oftentimes, recommendations from health care professionals are based on the results of multiple studies. So, if a news report focuses on 1 inquiry study, look at how many people were studied and if other studies had similar results. Also know that news stories are brief and often cannot put new research findings in their proper context.

Here are some mutual questions cancer survivors have had nearly nutrition and physical action. Equally you read this, go on in heed that a cancer survivor is defined as anyone who has been diagnosed with cancer, whether or non the person is in treatment.

Alcohol

Does alcohol increase the risk of cancer recurrence (coming back)?

Studies propose that drinking alcohol may increase the chance of dying for survivors of head and neck, laryngeal (vocalisation box), pharyngeal (throat), and liver cancer so it may exist all-time for survivors of those cancers to avoid booze. There isn't enough information at this time to know if drinking alcohol raises the risk of recurrence for other cancer types.

Nevertheless, cancer survivors are encouraged to make lifestyle changes to decrease their risk of developing a second cancer. Studies have plant a link betwixt booze intake and the gamble of getting a number of cancers, such as cancer of themouth, pharynx (pharynx),vox box (larynx), esophagus, liver, colon and rectum, and breast. Alcohol use may besides be linked to lung and tum cancer. For these cancers, it is best to avoid or limit alcohol intake.

Should I avoid alcohol during cancer treatment?

For people getting treated for cancer, the cancer type and phase (extent), as well as the type of treatment thing when deciding whether it's OK to drink alcohol during treatment. Many of the drugs used to care for cancer are cleaved down past the liver, and booze, past causing liver inflammation, could slow drug breakdown, increasing side furnishings. It'southward a good idea to avert or limit alcohol during treatment to foreclose interactions with the drugs used to treat cancer.

Alcohol, even in the small amounts used in mouthwashes, can irritate oral cavity sores and fifty-fifty make them worse. If you have oral fissure sores, you may be advised to avoid or limit alcohol. It may too be best to avoid or limit booze if you are starting treatment that volition put you at risk for oral cavity sores, such equally head and neck radiation or many types of chemotherapy.

Antioxidants

What exercise antioxidants have to do with cancer?

Antioxidants include vitamin C, vitamin E, carotenoids (compounds that give vegetables and fruits their colors), and many phytochemicals (plant-based chemicals). They assist prevent cell damage caused by chemical reactions with oxygen. Considering this harm may play a role in cancer development, it has long been thought that antioxidants may help preclude cancer.

Studies suggest that people who swallow more than vegetables and fruits, which are rich sources of antioxidants, may have a lower chance for some types of cancer. Because cancer survivors may be at increased adventure for second cancers, they should eat a variety of antioxidant-rich foods each day. (Second cancers are new, different cancers, not the aforementioned cancer coming back.)

So far, studies of antioxidant vitamin or mineral supplements have not found that they reduce cancer take chances. In fact, studies have shown that high-dose supplements of beta-carotene tin can increment the risk of lung cancer in people who are already at higher risk of this cancer. The best advice at this fourth dimension is to get antioxidants through your foods rather than supplements.

Is it rubber to take antioxidant supplements during cancer treatment?

Many dietary supplements contain levels of antioxidants (such every bit vitamins C and E) that are much college than the recommended Dietary Reference Intakes for optimal health.

For at present, many cancer doctors propose against taking high doses of antioxidant supplements during chemotherapy or radiation. There is a concern that the antioxidants might repair the impairment to cancer cells that these cancer treatments cause, making the treatments less constructive. But others accept noted that the possible harm from antioxidants is only in theory. They believe that at that place may exist a net benefit in helping to protect normal cells from harm caused by these cancer treatments.

Whether antioxidants or other supplements are helpful or harmful during chemotherapy or radiations handling is a major question without a articulate scientific discipline-based answer right now. Until more evidence is available, it's best for cancer survivors getting these treatments to avoid dietary supplements except to treat a known deficiency of a certain nutrient, and to avoid supplements that requite more 100% of the Daily Value for antioxidants.

Fat

Volition eating less fat lower the hazard of cancer coming dorsum or improve survival?

Several studies have looked at the link between fatty intake and survival after chest cancer. Results have been mixed. The most recent inquiry hasn't found a consequent link between the amount of fat eaten and chance of death later breast cancer. Some studies suggest that trans-fat intake might exist linked with an increased risk of death after breast cancer, but this needs to exist studied further. Trans fats as well have harmful effects on the heart, such every bit raising blood cholesterol levels. Although trans fats are existence removed from the food supply, survivors (peculiarly those at increased risk of centre illness) should avert trans fats as much as possible. Major sources of trans fats are margarines, broiled goods, and snack foods that contain partially hydrogenated oils.

Although information technology'southward not clear that total fatty intake affects cancer outcomes, diets very high in fat tend to be high in calories, likewise. This tin can lead to excess torso weight, which is linked to a higher risk of developing some types of cancer, a higher risk of a cancer coming back or death for survivors of breast, endometrial, and float cancers. In add-on, excess saturated fat intake is a known risk factor for heart illness, a major cause of death in all populations, including cancer survivors. The Mediterranean diet pattern, rich in olive oil (a source of monounsaturated fats), fish and nuts (rich in omega-iii fatty acids), vegetables, fruit, and whole grains take been linked to lower run a risk of death in prostate cancer survivors. This diet is also lower in saturated fat.

Fiber

Can dietary fiber prevent cancer or improve cancer survival?

Dietary fiber includes many unlike plant carbohydrates that are non digested past humans. Fibers are either soluble (like oat bran) or insoluble (like wheat bran and cellulose). Soluble fiber helps lower the hazard of heart illness by reducing claret cholesterol levels. Fiber is as well linked with improved bowel part. At this time, nosotros don't know if fiber itself can affect cancer take chances or survival.

Foods containing dietary cobweb, such equally beans, vegetables, whole grains, basics and fruits, however, are strongly linked with a lower hazard of colorectal cancer. These foods likewise have other health benefits, such every bit reduced take a chance of eye disease. For chest and prostate cancer survivors, eating a salubrious diet pattern rich in these foods is too associated with lower risk of decease.

Food safety

Are there special nutrient rubber precautions for people getting cancer treatment?

Infection is a special business organization for cancer survivors, peculiarly when the immune system is weak. (Blood tests are washed often during cancer treatment to check this.) Certain cancer treatments, such as chemotherapy, tin can weaken the immune system. When their allowed systems are weak, survivors should be careful to avoid eating foods that may contain unsafe levels of germs. Food should be handled safely; for example:

Launder your hands earlier and after preparing nutrient, and before eating.
Launder vegetables and fruits well.
Proceed hot foods hot (warmer than 140° F) and cold foods cold (cooler than 40° F).
Use special care when handling raw meats, fish, poultry, and eggs. Continue them away from other foods.
Thoroughly make clean all utensils, countertops, cutting boards, and sponges that accept touched raw meat.
Meat, poultry, and seafood should be thoroughly cooked. Utilise a food thermometer to check the internal temperatures of meats earlier serving.
Avoid raw honey, milk, and fruit juice, and choose pasteurized versions instead.
Shop foods in a refrigerator or freezer (beneath 40°F) correct after buying them to limit the growth of germs.
When eating out, avoid salad confined; sushi; and raw or undercooked meat, fish (including shellfish), poultry, and eggs—these foods are more likely to contain harmful bacteria.
If you lot apply well water in your habitation and are concerned about its safety (purity), ask your public health section to bank check information technology for bacteria.

Meats

Should I avert meats?

Studies take linked eating large amounts of red meat and processed meats (similar bacon, hot dogs, and cafeteria meats) with increased risk of colorectal and some other cancers. Some research besides suggests that frying, broiling, or grilling meats at very high temperatures creates chemicals that might increment the risk of some types of cancer (especially meats that are higher in fatty and poultry with skin).

For these reasons, the American Cancer Society Guideline for Nutrition and Physical Activity for Cancer Prevention recommends avoiding or limiting your intake of processed and red meats. It is recommended that cancer survivors also follow this guideline for general good wellness.

Research shows that a healthy eating pattern, which tends to be low in ruby and processed meats, is associated with higher overall survival for people with breast and prostate cancer. On the other hand, a "Western-style" nutrition, which is high in scarlet and processed meat, loftier-fatty dairy, refined grains, French fries, sweets and desserts, is associated with shorter survival in chest, colorectal, and prostate cancers, and too may increment the risk that colorectal cancer will come back. No studies have looked at the effect of processed meat, meat cooked at loftier temperature, or meat in general on cancer coming back or getting worse (progressing or growing).

Excess weight

Does existence overweight increase the risk of cancer coming back or getting another cancer?

For some types of cancer, existence overweight is linked to a college risk of cancer coming dorsum, as well as getting a second, different cancer.

In chest cancer survivors, being obese (BMI ≥thirty kg/m2) after diagnosis is associated with a college take chances of the cancer coming dorsum and a college gamble of death from breast cancer or whatsoever other cause.

In float cancer survivors, being overweight (>= 25 kg/m2) is linked with a higher risk of the cancer coming dorsum or getting worse. In endometrial cancer survivors, obesity is associated with a higher risk of dying.

It's non known if losing weight improves cancer outcomes for survivors. Nonetheless, because of other proven health benefits to losing weight, people who are overweight are encouraged to get to and stay at a healthy weight. Avoiding weight gain as an adult is of import, too, non only to reduce cancer risk and improve outcomes of some cancers, merely to reduce the risk of other chronic diseases every bit well.

Organic foods

Are foods labeled organic recommended for cancer survivors?

The term "organic" is often used for foods grown without pesticides and genetic modifications (changes). It'south besides used for meat, poultry, eggs, and dairy products that come up from animals that are not given antibiotics or growth hormones. The employ of the term organic on food labels is controlled by the US Department of Agriculture.

It'due south ordinarily thought that organic foods may be better for you considering they reduce exposure to certain chemicals. It has also been suggested that their nutrient makeup may be better than non-organic foods. It is non known if this means health benefits for those who swallow organic foods.

At this time in that location is non enough research in people to clearly land that organic foods are amend than other foods for reducing the hazard of getting cancer, having the cancer get worse, or of having the cancer come back. At this time, there are no studies in humans to evidence whether organic foods are improve than other foods in terms of reducing the adventure of cancer, the risk of cancer coming back, or the risk of cancer progression.

Physical activity

Should I exercise during cancer treatment and recovery?

Research strongly suggests that exercise is not only prophylactic during cancer handling, only it can likewise amend physical functioning and many aspects of quality of life. Moderate exercise has been shown to improve cancer-related symptoms and side effects, such equally fatigue (extreme tiredness), anxiety, low and sleep. It too helps heart and blood vessel fitness, muscle forcefulness, and body composition (how much of your body is made up of fat, bone, or muscle).

People getting chemotherapy and radiation who already practice may need to do and so at a lower intensity and build upwards more slowly than people who are not getting cancer handling. The main goal should be to stay as active equally possible and slowly increase your level of activity over time after handling.

Check with your cancer care team before starting any new physical activity or exercise plan to be certain you are being safe and following recommendations.

Tin can regular exercise improve cancer survival?

This has not been looked at for all types of cancer, simply in that location is strong prove that survivors who are physically agile afterwards a diagnosis of breast, colorectal, prostate, or female reproductive cancers (endometrial, ovarian and cervix combined) have a lower risk of death if they are more physically active.

Since physical action is known to preclude heart and blood vessel illness, diabetes, and osteoporosis, all cancer survivors should try to be physically active. Be sure to talk to your cancer care team nigh how concrete activity might be afflicted by your type of cancer, symptoms, and side effects of treatment

Phytochemicals

What are phytochemicals, and practise they reduce cancer risk?

Phytochemicals are a wide range of compounds made by plants. Some have either antioxidant or hormone-like actions. Only a few studies accept looked at the furnishings that phytochemicals (or the plants that incorporate them) may accept on cancer coming back or getting worse (progressing).

Eating lots of vegetables and fruits reduces the risk of some types of cancer, and so researchers are looking for the specific plant compounds that might account for this. At this time at that place is no evidence that phytochemicals taken as supplements are as helpful as the vegetables, fruits, beans, and grains they come from. In fact, some phytochemicals may be harmful and so be certain to talk with your cancer intendance team before taking whatever types of supplements.

Soy products

Should cancer survivors include soy-based foods in their diet?

Soy foods are an excellent source of protein and tin exist a good option for meals without meat. Soy contains many phytochemicals, including isoflavones, some of which have weak estrogen activity and seem to protect against hormone-dependent cancers in animal studies. Other compounds in soy have antioxidant properties and may have anticancer effects.

There's a cracking deal of interest in the possible part of soy foods in reducing cancer risk, especially breast cancer adventure. Some studies suggest that eating traditional soy foods like tofu may lower breast cancer risk, especially among Asian women who may have consumed soy in larger amounts for longer time periods, but testify is still limited.

Less is known about the furnishings of soy supplements, which were shown in one study to increase hazard of estrogen receptor-negative breast cancer, and increment breast cancer risk in women with a family unit history of cancer.

For the breast cancer survivor, current research finds no harmful effects from eating soy foods and indicates that consuming soy foods rich in isoflavones may lower the chance of recurrence. These foods may even help tamoxifen piece of work amend. Still, be careful using soy supplements, as petty is known about their helpful and harmful health effects in cancer survivors.

Sugar

Does sugar "feed" cancer?

Saccharide intake has not been shown to increment the risk of getting cancer or having information technology get worse (progress). Nevertheless, sugars and sugar-sweetened drinks add large amounts of calories to the nutrition and can cause weight gain, which we know tin can affect cancer outcomes.

There are many kinds of sugars, including honey, raw sugar, chocolate-brown saccharide, corn syrup, and molasses. Many drinks, such equally soft drinks and fruit-flavored beverages contain added sugar. Near foods and drinks that are loftier in added sugar practice non offer many nutrients and may replace more than nutritious food choices. For this reason, limiting the intake of foods and drinks with added sugar is recommended.

Supplements

Would survivors do good from using vitamin and mineral supplements?

Survivors should endeavor to get the nutrients they need through nutrient, not supplements. Use dietary supplements simply when your doctor tells you to take them because of a deficiency of a certain nutrient. Do not accept vitamins or other supplements to go higher than recommended levels of nutrients—this may do more than harm than good.

Can nutritional supplements lower cancer risk or the risk of cancer coming back?

There is no testify at this fourth dimension that dietary supplements can lower the chance of cancer coming back or improve survival. In fact, studies have shown that loftier-dose supplements of beta-carotene can increase the gamble of lung cancer in people who are already at higher adventure of this cancer and should be avoided.

However, there is potent evidence that a nutrition rich in vegetables, fruits, and other plant-based foods may reduce the risk of some types of cancer. And some recent studies suggest there may exist a helpful issue on recurrence or survival for chest and prostate cancers. Simply there is no evidence at this time that supplements tin can provide these benefits. Many healthful compounds are found in vegetables and fruits, and information technology'south likely that these compounds work together to create these helpful effects. Nutrient is the best source of vitamins and minerals.

Vegetables and fruits

Will eating vegetables and fruits lower the risk of cancer coming back?

In most studies, eating more vegetables and fruits has been linked with a lower risk of lung, oral (mouth), esophagus (tube connecting the mouth to the tummy), tum, and colon cancer. But few studies take been done on whether a diet that includes many vegetables and fruits tin can reduce the take a chance of cancer coming back (recurrence) or ameliorate survival. Studies that look at overall healthy dietary patterns containing vegetables and fruit, legumes, whole grains and those that are low in red and processed meat have been linked with longer overall survival later on breast and prostate cancers.

Even so, cancer survivors should swallow a multifariousness of colorful vegetables and fruits each day because of their other health benefits. It's non known which of the compounds in vegetables and fruits are virtually protective, so it's best to eat different kinds of colorful vegetables and fruits every solar day.

Is there a deviation in the nutritional value of fresh, frozen, and canned vegetables and fruits?

Yes, merely they can all be good choices. Fresh foods are usually thought to have the most nutritional value. Simply some frozen foods can have more nutrients than fresh foods. This is because they are often picked ripe and quickly frozen, and nutrients tin can be lost in the time betwixt harvesting and eating fresh foods.

Canning is more than likely to reduce the heat-sensitive and water-soluble nutrients because of the high temperatures used in the canning process. Also, be aware that some fruits are packed in heavy syrup, which has a high sugar content, and some canned vegetables are high in sodium.

Choose different forms of whole vegetables and fruits.

Does cooking touch on the nutritional value of vegetables?

Cooking vegetables and fruits can aid y'all better absorb certain nutrients, similar carotenoids (compounds that requite vegetables and fruits their colors). Microwaving and steaming are the best means to preserve the nutrients, while boiling, peculiarly for a long time, tin leach out the water-soluble vitamins.

Should I juice my vegetables and fruits?

Juicing tin can add variety to your diet and can be a good style to get vegetables and fruits, particularly if y'all have trouble chewing or swallowing. Juicing also helps the body blot some of the nutrients in vegetables and fruits. Only juices may be less filling than whole vegetables and fruits, and they contain less cobweb. Drinking a lot of fruit juice can too add extra calories and uncomplicated sugars to a person's nutrition.

Buy juice products that are 100% vegetable or fruit juices and pasteurized to remove harmful germs. These are better for everyone merely are particularly important for people who may take weak immune systems, such as those getting chemotherapy.

Vegetarian diets

Exercise vegetarian diets reduce the adventure of cancer coming dorsum?

No stiff evidence has shown that vegetarian diets assist reduce the hazard of cancer coming dorsum when compared to a diet that is high in vegetables, fruits, and whole grains and contains minor amounts of meat and fish. But vegetarian diets tin be healthy considering they tend to exist depression in saturated fat and high in fiber, vitamins, and phytochemicals.

The American Cancer Society Guideline for Diet and Physical Activity for Cancer Prevention defines a healthy, cancer-preventive diet as one that is nutrition rich in vegetables, fruits, legumes and whole grains and limits or does not include scarlet and processed meats, sugar-sweetened beverages, highly candy foods and refined grain products. Several eating patterns tin can run across this definition, including the Mediterranean diet, the Dash nutrition and vegetarian diets.

Water and other fluids

How much water and other fluids should I drink?

Symptoms similar fatigue (farthermost tiredness), light-headedness, dry out mouth, a bad gustatory modality in the mouth, and nausea can be acquired by dehydration (loss of fluid from the body). To help prevent these bug, survivors should endeavor to take in enough fluids. This is peculiarly important if you lot are losing fluid, such equally through vomiting or diarrhea.

Salubrious adult men need about iii.7 liters of water a day, while women need about two.vii liters, just most of this fluid comes from foods. (Annotation: A liter is a piffling over a quart or 4 viii-ounce cups.)

If you are having trouble eating or drinking or are losing fluid (because of problems with vomiting or diarrhea, for instance), you might not be able to take in enough fluid. Talk with your cancer care team or principal care provider about how y'all tin get more fluids.

How tin can I discover a nutrition or exercise professional?

Cancer survivors can benefit from nutrition and physical action cess and counseling equally soon every bit possible after diagnosis and standing through the cancer episode, as needed. If you are looking for professional assist to address diet and practice, you can inquire your cancer care team or principal care provider for a referral.

You tin can also search for nutrition professionals in your surface area on the Academy of Diet and Dietetics website.

The American College of Sports Medicine Moving Through Cancer website has a directory of hospital and community-based practise programs for cancer survivors.
