The most frequently diagnosed cancer males and the third most common cause of cancer-related death in men is prostate cancer. Because it is a slow-growing cancer, it may never cause symptoms and is often only detectable by a PSA blood test, which measures levels of PSA, an enzyme produced by the prostate. Nutrigenomics is a new science that seeks to understand how diet affects genetics, and researchers hope to someday design diets that delay the genetically based disease. Prostate cancer has been the poster child for this type of research because of its high incidence and the relative longevity of the patients.
What is a normal PSA?
Normal blood levels of PSA depend on age and medical history.
- 3 or less is normal for men under 60
- 4 or less for age 60 – 69
- 5 or less for over 70
- A reading over 10 can indicate cancer or a benign infection. Men should discuss the limitations of the test–especially false- positive readings- with their health care professional.
With over 500,000 new cases of prostate cancer diagnosed annually world-wide, and with the disease a major factor in 200,000 deaths each year, it is an issue men can not ignore. Not surprisingly, prostate cancer num- bers are lower in populations that tend to drink green tea, and studies confirm the beverage inhibits prostate cancer. Fortunately, even if you have already received a diagnosis, you can benefit from the healing effects of green tea. A Japanese study performed on 49,920 men between the ages of 40-69 found that drinking five or more cups a day was associated with a 48% reduction in advanced prostate cancer risk, compared to drinking less than one cup per day.
