The prostate is the gland below a man's bladder that produces fluid for semen. Prostate cancer is the third most common cause of death from cancer in men of all ages. It is rare in men younger than 40. Levels of a substance called prostate specific antigen (PSA) is often high in men with prostate cancer. However, PSA can also be high with other prostate conditions. Since the PSA test became common, most prostate cancers are found before they cause symptoms. Symptoms of prostate cancer may include Problems passing urine, such as pain, difficulty starting or stopping the stream, or dribbling Low back pain Pain with ejaculation Prostate cancer treatment often depends on the stage of the cancer. How fast the cancer grows and how different it is from surrounding tissue helps determine the stage. Treatment may include surgery, radiation therapy, chemotherapy or control of hormones that affect the cancer.

ScienceDaily (July 2, 2006) - Drinking an eight ounce glass of pomegranate juice daily increased by nearly four times the period during which PSA levels in men treated for prostate cancer remained stable, a three-year UCLA study has found.

"(NaturalNews) Treatment with vitamin D supplements may slow the progress of , according to a study published in the journal BJU International. In the United States, prostate cancer is the second leading cause of cancer death among men, after lung cancer. Approximately 240,000 new cases are diagnosed every year, leading to 30,000 deaths. Researchers have suspected for nearly two decades that the so-called "sunshine vitamin" may play a role in the risk and progression of prostate cancer, but no studies have previously been conducted on its usefulness as a treatment."

The Toronto group gave a fixed low dose (2,000 units) of the prehormone, cholecalciferol, a very safe compound that never causes high calcium in the doses used. In fact, the lowest dose of cholecalciferol known to cause high blood calcium is more than 20,000 units. Therefore, the Toronto group got better results with one-tenth the comparable dose of deltanoids! Vieth wanted to use more cholecalciferol but widespread ignorance about the physiology and pharmacology of vitamin D remains and he could not get adequate dosing past the various review committees.

A chemical found in green tea appears to slow the progression of prostate cancer, a study has suggested. Green tea has been linked to a positive effect on a wide range of conditions, including heart disease, cancer and Alzheimer's disease.
