About prostate cancer
The prostate is a gland in the reproductive system. It is located just below the bladder and is about the size of a large walnut. Prostate cancer can begin growing in the cells of the prostate and potentially spread to other parts of the body.

Are there any foods I can eat to reduce my risk of prostate cancer?
Some foods have been associated with a decreased risk of prostate cancer, but more research is needed to confirm the benefits. These include:
Should I take supplements to lower my risk of prostate cancer?
No. Eating a variety of foods is the best way to get vitamins, minerals and other cancer fighting compounds. Research has shown that taking supplements like selenium or beta carotene do not help reduce prostate cancer risk. Speak with dietitian if you are thinking about taking vitamin, mineral or herbal supplements.
What about calcium supplements?
If you have trouble getting enough calcium from foods, talk to your dietitian or health care professional about a calcium supplement. You need 1000 mg of calcium per day if you are 19 to 70 years of age and 1200 mg if you are over 70. Getting enough calcium is important for bone health, but getting more calcium than you need may increase your risk of prostate cancer.
Should I get screened for prostate cancer?
Speak to your health care professional about getting screened. Your doctor may recommend specific tests to assess your risk. Learn more about prostate cancer screening screened.
How can a dietitian help?
A dietitian can support you in making changes to your diet that help lower your risk of prostate cancer. For example, a dietitian can give you advice on how much calcium to eat in a day, which supplements you may need and how to maintain a healthy weight that is right for you.

More research still needs to be done to know for sure which foods impact your risk of prostate cancer. In the meantime, aiming for a healthy weight and eating a nutritious diet is important for reducing risk of cancer.
