Preventing Prostate Cancer
To date, no evidence proves that prostate cancer can be prevented. However, you may be able to lower your risk.
A low-fat diet that consists primarily of vegetables, fruits, and grains may help reduce your risk for prostate cancer. The American Cancer Society recommends limiting high-fat foods from animal sources. Eat five or more servings of fruits and vegetables each day. Healthy food choices also include bread, cereals, rice, pasta, and beans.
Substances in foods, especially fruits and vegetables, called antioxidants help prevent damage to the DNA in the body's cells. Such damage has been linked to disease, including cancer. Lycopenes, in particular, are antioxidants that have been linked to lower risk of prostate cancer. They are in foods such as tomatoes (raw or cooked), spinach, artichoke hearts, beans, berries (especially blueberries), pink grapefruit and oranges, and watermelons. Read more about antioxidant-rich vegetables and beans and fruits.
In some hospitals, clinical trials are underway to look at various "chemoprevention" protocols designed to lower the prostate cancer risk. So far, it's too soon to know if there are any new ways to prevent prostate cancer.
Using vitamin supplements may affect your risk of prostate cancer. Some studies show that taking vitamin E may lower your risk of prostate cancer whereas other studies show no effect on cancer risk. Taking selenium may also lower your risk. There is currently a large ongoing study to evaluate if either of these supplements can provide protection from prostate cancer.
Before taking any supplements it is advisable to first talk with your doctor. In some hospitals, clinical trials are underway to look at various "chemoprevention" protocols designed to lower the prostate cancer risk. So far, it's too soon to know if there are any new ways to prevent prostate cancer.
Studies of men taking the drug Proscar have shown they were about 25% less likely to develop prostate cancer when compared to those taking a placebo. Proscar is currently used to treat benign prostatic hyperplasia (BPH). Results of these findings revealed that taking Proscar was associated with an increased risk of sexual side effects and prostate cancers that had a tendency to be more aggressive (higher grade). At this time, it is not certain if it is beneficial to take Proscar to prevent prostate cancer.
Screening Guidelines
Not all medical institutions and advocacy groups agree on when men should be screened (routinely tested) for prostate cancer. But, as is the case with most other types of cancer, early detection often means more treatment options are available and less extensive treatment is necessary.
General Recommendations:
- Annual digital rectal exams beginning at age 40.
- PSA testing Beginning at age 50 followed by testing every other year.
- Annual digital rectal exams and PSA testing beginning at age 40 for black men and those with a family history of prostate cancer.
