Herbal anti-cancer supplements -
Research has shown that lycopene in food appears to reduce prostate cancer risk; however, this remains controversial. Verdict: Once again, we don't know how lycopene works in the body -- or whether it's working alone -- to reduce cancer risk. Consider this: Researchers noted that foods rich in beta-carotene -- a cousin to lycopene -- seemed to reduce lung cancer risk in smokers.
But when beta-carotene supplements were tested by smokers as a preventive, cancer risk increased. Leave lycopene supplements alone.
Instead, eat more tomato sauce, low-sodium tomato juice, watermelon, guava, rose hips and pink grapefruit. Charge: Melatonin is a hormone found in the body. Doctors sometimes prescribe a synthetic form of it to supplement cancer treatment or ward off side effects. Melatonin also is used to treat insomnia.
Research is under way to determine whether melatonin helps boost the immune system. Verdict: If you are having problems sleeping, it might be worth talking to your doctor about melatonin.
However, do not take this supplement -- or any other -- without consulting your doctor first. Some melatonin supplements may contain contaminants.
Melatonin is known to interact with certain medications -- including blood pressure drugs -- and may worsen depression. Charge: Resveratrol is a polyphenol known to act as an antioxidant, an antiinflammatory and a weak plant estrogen. These properties may help it to prevent cellular damage known to trigger cancer, but its ability to slow the growth of cancer cells has only been shown in early laboratory testing.
Verdict: Resveratrol is found in grape skins, so eat more red and purple grapes. It's too soon to know how resveratrol works or whether resveratrol supplements are safe, so don't take resveratrol pills -- or uncork the red wine.
While it's true that resveratrol is found in wine, it's also true that alcohol consumption is associated with increased cancer risk.
Resveratrol may have an estrogenic effect, so women with hormone-sensitive conditions, in particular, should avoid resveratrol supplements. Charge: Selenium is a mineral found in poultry, fish, wheat and liver.
It was once thought to be potentially beneficial in preventing cancer. However, several studies have shown that it is not only ineffective, but also potentially dangerous. Studies have shown it does not prevent skin, lung, prostate, stomach and esophageal cancer.
Furthermore, research conflicts as to whether it may increase risk for a type of skin cancer called squamous cell carcinoma. Last year, a trial examining vitamin E and selenium for prostate cancer prevention was halted after researchers noted a small increase in diabetes among men who took selenium.
Charge: Turmeric, a curry spice, has anti-inflammatory properties and contains an antioxidant called curcumin. In very early basic laboratory studies, curcumin has been shown to stop the spread of melanoma cells. One trial showed that selenium might protect against the overall risk of prostate cancer in men with a history of non melanoma skin cancer.
But a later systematic review found that selenium supplements had no benefit in protecting against cancer. Some randomised controlled trials showed a higher incidence of high grade prostate cancer and type 2 diabetes in people taking selenium supplements. Research in this area has produced mixed results.
Doctors don't recommend that people take it to treat cancer or reduce the risk of cancer. People often take vitamin C in much higher doses than the recommended nutrient intake RNI of 40mg per day.
Some people take it as a drip into the bloodstream IV. There is no good quality research to say that vitamin C helps chemotherapy to work better or help to reduce its side effects.
Research continues to look at the role of vitamin D in the development and recurrence of different cancers. Some early studies suggest that there is a link between low levels of vitamin D and the development of cancer.
However, vitamin D is important for keeping our bones healthy. We need it to absorb calcium. Most of our vitamin D comes from sunlight, but some comes from our diet. The Government recommends that all people in the UK consider take 10 micrograms of vitamin D in the autumn and winter.
Some adults at risk of vitamin D deficiency are recommended to take a supplement throughout the year. Check with your healthcare team or GP if you think you should be taking vitamin D supplements. MedlinePlus in the USA has information about vitamins and minerals used as dietary supplements.
They provide information about possible side effects and research about vitamins and cancer. A complementary therapy means you can use it alongside your conventional medical treatment. It may help you to feel better and cope better with your cancer and treatment. An alternative therapy is generally used instead of conventional medical treatment.
Some therapies may be harmful or could interact with other treatments you're having. Talk to your doctor before starting any complementary or alternative therapy. Find detailed information and research into some of the many different complementary and alternative therapies used by people with cancer.
Research into complementary and alternative therapies is important so that we know if they are safe to use, whether they work, and to find out if they interact with conventional cancer treatments. Many people use the internet to get medical information.
This can affect their treatment choices. It is important to use reliable and professional organisation websites for this. Cancer Chat is our fully moderated forum where you can talk to others affected by cancer, share experiences, and get support.

Summary Try to eat a balanced diet with plenty of fresh fruit and vegetables. Low levels of nutrients can make you feel ill.
Use supplements under the supervision of your medical team and a dietitian. What are vitamins, minerals and other nutrients? Some examples of these various nutrients are: vitamins A, C, D and E minerals — like zinc, calcium, selenium and magnesium essential fats essential amino acids — like phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, leucine, and lyseine some plant compounds phyto nutrients or botanicals — like carotenoids, flavonoids, and isoflavones You might find that your cancer or your cancer treatment makes it difficult to eat or drink properly.

A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients.
During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard.
Some clinical trials are open only to patients who have not started treatment. Clinical trials can be found online at NCI's website. For more information, call the Cancer Information Service CIS , NCI's contact center, at CANCER PDQ is a registered trademark.

Complementary and alternative medicine CAM —also called integrative medicine—includes a broad range of healing philosophies, approaches, and therapies.
A therapy is generally called complementary when it is used in addition to conventional treatments; it is often called alternative when it is used instead of conventional treatment.
Conventional treatments are those that are widely accepted and practiced by the mainstream medical community. Depending on how they are used, some therapies can be considered either complementary or alternative.
Complementary and alternative therapies are used in an effort to prevent illness, reduce stress, prevent or reduce side effects and symptoms, or control or cure disease.
Unlike conventional treatments for cancer, complementary and alternative therapies are often not covered by insurance companies. Patients should check with their insurance provider to find out about coverage for complementary and alternative therapies. Cancer patients considering complementary and alternative therapies should discuss this decision with their doctor, nurse, or pharmacist as they would any type of treatment.
Some complementary and alternative therapies may affect their standard treatment or may be harmful when used with conventional treatment. It is important that the same scientific methods used to test conventional therapies are used to test CAM therapies.
The National Cancer Institute and the National Center for Complementary and Integrative Health NCCIH are sponsoring a number of clinical trials research studies at medical centers to test CAM therapies for use in cancer.
Conventional approaches to cancer treatment have generally been studied for safety and effectiveness through a scientific process that includes clinical trials with large numbers of patients.
Less is known about the safety and effectiveness of complementary and alternative methods. Few CAM therapies have been tested using demanding scientific methods. A small number of CAM therapies that were thought to be purely alternative approaches are now being used in cancer treatment—not as cures, but as complementary therapies that may help patients feel better and recover faster.
One example is acupuncture. According to a panel of experts at a National Institutes of Health NIH meeting in November , acupuncture has been found to help control nausea and vomiting caused by chemotherapy and pain related to surgery. However, some approaches, such as the use of laetrile, have been studied and found not to work and to possibly cause harm.
