Prostate Cancer, Nutrition, and Dietary Supplements (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Green Tea
OverviewThis section contains the following key information:All tea originates from the Camellia sinensis (L.) Kuntze plant, and the methods by which the leaves are processed determine the type of tea produced. For green tea, the leaves are steamed and dried.Some research suggests that green tea may have a protective effect against cardiovascular disease and against various forms of cancer, including prostate cancer.Catechins are polyphenol compounds in tea that are associated with many of tea's proposed health benefits.Epigallocatechin gallate (EGCG), the most abundant catechin in tea, acts as an androgen antagonist and can suppress prostate cancer cell proliferation, suppress production of prostate-specific antigen (PSA) by prostate cancer cells, and increase prostate cancer cell death in vitro.Results from one in vitro study showed that prostate cancer cells were less susceptible to radiation -induced apoptosis when exposed to EGCG 30 minutes
Prostate Cancer, Advanced or Metastatic - Treatment Options for Recurrent Prostate Cancer
Standard treatment of recurrent prostate cancer may include the following:Chemotherapy.Biologic therapy with sipuleucel-T for patients already treated with hormone therapy.Hormone therapy.Radiation therapy.Prostatectomy for patients already treated with radiation therapy.Treatment to control pain from cancer that has spread to the bone may include the following:Pain medicine.External-beam radiation therapy.Internal radiation therapy with radioisotopes such as strontium-89.Targeted therapy with a monoclonal antibody.Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with recurrent prostate cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. General information about clinical trials is available from the NCI Web site.
Prostate Cancer, Nutrition, and Dietary Supplements (PDQ®): Complementary and alternative medicine - Patient Information [NCI] - Questions and Answers About Green Tea
What is green tea?Tea has been consumed in Asia since ancient times. Sailors first brought tea to England in the 17th century. Other than water, tea is the most widely consumed beverage in the world. Tea comes from the Camellia sinensis plant. The way the leaves of this plant are processed determines the type of tea produced. Many of the possible health benefits studied in green tea are thought to be from compounds called polyphenols. Polyphenols are a large group of plant chemicals that include catechins (antioxidants that help protect cells from damage caused by free radicals).Catechins make up most of the polyphenols in green tea. The most active catechin in green tea is epigallocatechin-3-gallate (EGCG).To make green tea, the tea leaves are roasted in a wok (or, historically, steamed) to preserve the catechins and retain freshness. Black tea is made using a process that causes the catechins and other compounds in the leaves to oxidize, producing darker colored tea. Oolong tea is

Prostate Cancer Screening (PDQ®): Screening - Health Professional Information [NCI] - General Information About Prostate Cancer
Prostate cancer is a disease in which malignant (cancer) cells form in the tissues of the prostate. The prostate is a gland in the male reproductive system located just below the bladder (the organ that collects and empties urine) and in front of the rectum (the lower part of the intestine). It is about the size of a walnut and surrounds part of the urethra (the tube that empties urine from the

Prostate Cancer Screening (PDQ®): Screening - Health Professional Information [NCI] - Stage I Prostate Cancer Treatment
OverviewStage I prostate cancer is defined by the American Joint Committee on Cancer's TNM classification system:T1a–c, N0, M0, prostate-specific antigen (PSA) <10 ng/ml, Gleason ≤6.T2a, N0, M0, PSA <10 ng/ml, Gleason ≤6.T1–2a, N0, M0, PSA X, Gleason X.The frequency of clinically silent, nonmetastatic prostate cancer that can be found at autopsy greatly increases with age and may be as high as 50% to 60% in men aged 90 years and older. Undoubtedly, the incidental discovery of these occult cancers at prostatic surgery performed for other reasons accounts for the similar survival of men with stage I prostate cancer, compared with the normal male population, adjusted for age. Many stage I cancers are well differentiated and only focally involve the gland (T1a, N0, M0); most require no treatment other than careful follow-up.In younger patients (aged 50–60 years) whose expected survival is long, treatment should be considered.
