Zyflamend contains extracts of rosemary, turmeric, ginger, holy basil, green tea, hu zhang (Polygonum cuspidatum, a source of resveratrol), Chinese goldthread, barberry, oregano, and Baikal skullcap.The extracts found in Zyflamend have anti-inflammatory activity and possible anticancer benefits. There is limited evidence about how Zyflamend may act against tumor growth. Zyflamend has been shown to interfere with the activity of COX-1 and COX-2 enzymes, which are involved in the development of inflammation and possibly cancer. Zyflamend may also act against the NF-kappa B and lipoxygenase (LOX) families of proteins that stimulate tumor growth. How is Zyflamend administered or consumed?Zyflamend is taken as a dietary supplement in capsule form. Have any preclinical (laboratory or animal) studies been conducted using Zyflamend?Laboratory and animal research has recently been done to study the effects of
Questions and Answers About Soy
What is soy?The soybean plant has been grown in Asia for food since ancient times. Soy first arrived in Europe and North America in the 18th century. The soybean can be processed into a wide variety of products including soy milk, miso, tofu, soy flour, and oil. Soy foods contain many phytochemicals that may have health benefits. Isoflavones are the most widely researched compounds in soy. Major isoflavones in the soybean include genistein (which may be the most bioactive isoflavone), daidzein, and glycitein. Isoflavones protect the soybean plant from stress and have antioxidant, antimicrobial, and antifungal actions.Isoflavones are phytoestrogens (estrogen -like substances found in plants) that attach to estrogen receptors in cells. Genistein has been shown to affect many pathways in prostate cancer cells involved in the growth and spread of cancer. How is soy administered or consumed? Soy may be consumed in the diet or taken in dietary supplements. Have any preclinical (laboratory

Prostate Cancer Screening
Tests are used to screen for different types of cancer. Some screening tests are used because they have been shown to be helpful both in finding cancers early and decreasing the chance of dying from these cancers. Other tests are used because they have been shown to find cancer in some people; however,it has not been proven in clinical trials that use of these tests will decrease the risk of ...
Treatment Options by Stage
Stage I Prostate Cancer Treatment of stage I prostate cancer may include the following: Watchful waiting. Radical prostatectomy,usually with pelvic lymphadenectomy,with or without radiation therapy after surgery.

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. All tea comes from the Camellia sinensis plant. The way the leaves of this plant are processed determines the type of tea produced. To make green tea, the tea leaves are steamed and dried; this causes very little oxidation (a chemical reaction that takes place when a substance comes into contact with oxygen or another oxidizing substance). Black tea is made by crushing tea leaves to cause full oxidation. Oolong tea is made from partially oxidized leaves.Some studies suggest that green tea may protect against cardiovascular disease and some types of cancer. Clinical trials designed to study whether green tea is useful in treating prostate cancer are in the early stages. There is not enough evidence to show whether green tea is effective in treating prostate cancer.Many of the possible
Recurrent Prostate Cancer Treatment
OverviewIn recurrent prostate cancer, the selection of further treatment depends on many factors, including:Previous treatment.Site of recurrence.Coexistent illnesses.Individual patient considerations. Definitive radiation therapy can be given to patients with disease that fails only locally following prostatectomy.[1,2,3,4] An occasional patient can be salvaged with prostatectomy after a local recurrence following definitive radiation therapy; however, only about 10% of patients treated initially with radiation therapy will have local relapse only. In these patients, prolonged disease control is often possible with hormonal therapy, with median cancer-specific survival of 6 years after local failure.Cryosurgical ablation of recurrence following radiation therapy is associated frequently with a high complication rate. This technique is still undergoing clinical evaluation.Hormonal therapy is used to manage most relapsing patients with disseminated

Stages of Prostate Cancer
After prostate cancer has been diagnosed,tests are done to find out if cancer cells have spread within the prostate or to other parts of the body. The process used to find out if cancer has spread within the prostate or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order .
General CAM Information
Complementary and alternative medicine (CAM)—also referred to as integrative medicine—includes a broad range of healing philosophies, approaches, and therapies. A therapy is generally called complementary when it is used in addition to conventional treatments; it is often called alternative when it is used instead of conventional treatment. (Conventional treatments are those that are widely accepted and practiced by the mainstream medical community.) Depending on how they are used, some therapies can be considered either complementary or alternative. Complementary and alternative therapies are used in an effort to prevent illness, reduce stress, prevent or reduce side effects and symptoms, or control or cure disease. Unlike conventional treatments for cancer, complementary and alternative therapies are often not covered by insurance companies. Patients should check with their insurance provider to find out about coverage for complementary and alternative therapies. Cancer patients
