Prostate cancer affects mainly older men. Four out of five cases are diagnosed in men over 65, but less than 1% in men under 50. Though uncommon, prostate cancer can be seen in men even in their 30's and 40's. Men with a family history of prostate cancer are more likely to develop prostate cancer than the general population.
On a case-by-case basis, doctors cannot say with certainty what causes prostatecancer, but experts generally agree that diet contributes to the risk. Men who consume large amounts of fat -- particularly from red meat and other sources of animal fat -- are more likely to develop advanced prostate cancer. The disease is much more common in countries where meat and dairy products are dietary staples than in countries where the basic diet consists of rice, soybean products, and vegetables such as broccoli, cauliflower, cole slaw, or sauerkraut.
The outlook for men diagnosed with prostate cancer has never been brighter. Doctors now have a variety of ways to treat prostate cancer, including surgery, radiation, and drugs that slow the growth of cancer cells. Both the safety and effectiveness of prostate cancer treatments has been steadily improving.
That’s good news, of course. But with so many different approaches to prostate cancer treatment, each with its own benefits and risks, weighing your options and choosing the most appropriate treatment...
The underlying factor linking diet and prostate cancer is probably hormonal. Fats stimulate increased production of testosterone and other hormones, and testosterone acts to speed the growth of prostate cancer. High testosterone levels may stimulate dormant prostate cancer cells into activity. Some findings msuggest that high testosterone levels also influence the initial onset of prostate cancer. Eating meat may be risky for other reasons, such as meat cooked at high temperatures produces cancer-causing substances that directly affect the prostate. Other risk factors have been noted. Welders, battery manufacturers, rubber workers, and workers frequently exposed to the metal cadmium seem to be abnormally vulnerable to prostate cancer.
The following are associated with an increased risk of advanced prostate cancer: Height, high body mass index, low physical activity, smoking, low tomato sauce consumption, high calcium intake, high linoleic acid intake, African-American race, and a positive family history.
