Prostate specific antigen or PSA is a protein produced by the prostate gland. PSA liquefies the semen to allow sperm cells freedom of movement. While low levels of PSA in the blood are normal, an higher level indicates a problem. PSA results are still unreliable as a stand-alone test. You must undergo a doctor's examination and further testing. Scientists believe nutrients such as Lycopene and Boron interfere with PSA activity. The data suggest you can lower your risk of prostate cancer with high intake of these and other nutrients. Patients can slow the progression and spread of prostate cancer.

Eat tomatoes or tomato sauce. Rich in lycopene, tomatoes cut PSA levels, as well as DNA damage in the prostate tissue. Aid cancer treatment by eating tomatoes. Use 30 mg a day in natural lycopene supplements as an alternative.
Take a Boron supplement. A study by M.T. Gallardo-Williams demonstrated that PSA levels in mice decreased by about 87 per cent when injected with the supplement. Tumours shrank an average of 31.5 per cent.
Drink green tea. Green tea has epigallocatechin gallate or EGCG that restrains PSA expression and inhibits prostate cancer cells. Scientists have had success with supplement tablets as well.
Take prescription medication. Medicines such as Avodart and Proscar cut your PSA levels by half. They do this by inhibiting an enzyme called 5-alpha reductase, an enzyme that transforms testosterone into dihydrotestosterone. Dihydrotestosterone's growth promoting effect on prostate cells is up to 10 times greater than that of testosterone.
Lower your overall and low-density lipoprotein or LDL cholesterol. Researchers at Duke University discovered men with lower LDL and overall cholesterol levels also had lower PSA levels. Those taking prescription statins also experienced declines in their PSA levels.
Eat authentic Japanese cuisine, which is rich in phytoestrogens. Order or cook items such as natto (fermentedsoybeans), miso soup (soybean paste soup), aburaage (fried bean curd), kinako (soy flour), yuba (dried bean curd) or tonyu (soybean milk). Use soy sauce when possible.
Increase your soy consumption. If you favour domestic food, visit your local market and find soy products. You'll find green soybeans, bean sprouts, milk, cookies, garden burgers, meat, beans, nuts, tofu, and cake or pancake mixes.
Take a high-quality soy bread supplement. Scientists at Australia's Monash University saw a 12.7 per cent reduction in PSA levels in men with prostate cancer who used soy bread supplements.
