Brain Metastases is a cancer that has spread to the brain from another site in the body, commonly the lung or breast. Other primary tumors that metastasize to the brain include melanoma , sarcomas, and tumors arising in the kidney or colon. In addition, unknown primaries sometimes present with brain metastases. The incidence of brain metastasis is far more prevalent than primary brain cancer. When a cancer spreads (metastasizes) from its original site to another area of the body, it is termed metastatic cancer. Virtually all cancers have the potential to develop this way. Whether metastases do develop depends on the complex interaction of many tumor cell factors, most of which are not completely understood. Metastases spread in three ways - by local extension from the tumor to the surrounding tissues; through the bloodstream to distant sites; or through the lymphatic system to neighboring or distant lymph nodes. Each kind of cancer may have a typical route of spread. Many patients have no ...
Radiation Therapy Radiation therapy may be used as an initial treatment for localized prostate cancer. It may also be used as treatment for cancer that has not been fully removed or has recurred after surgery. In advanced cancer, radiation therapy is used to shrink the size of the tumor and relieve symptoms. Radiation therapy used to be reserved for older men (over age 70) with locally advanced prostate cancer who had a life expectancy of 15 years or less. However, it is now being used more frequently in younger and healthier men. The two main radiation treatments for prostate cancer are: External beam radiation Brachytherapy (internal radiation) Both treatments have generally equal success rates. In some cases, both techniques may be used in high-risk patients. External Beam Radiation In external beam radiation therapy, a doctor focuses a beam of radiation directly on the tumor for 35 three-minute treatments given five times a week over 7 weeks. Three-dimensional (3-D) conformal techniques u...
Ever since they first appeared in this country, some hundred
years ago, professional baseball games have been a quintessential
opportunity for millions of American fathers to bond with their
children. On June 16th, in commemoration of Fathers Day,
Major League Baseball altered one of the games most storied
traditionsthe seventh-inning stretchas a public service
to these same fathers. To raise awareness for prostate cancer, fans
in baseball stadiums across the country sang Take Me Out to
the Ballgame last Sunday after the sixth inning, a symbolic
gesture that refers to the fact that one in six American men will
develop prostate cancer at some point in their life. A public
service message, promoting regular prostate exams as well as
general cancer awareness, was displayed on the big screen during
the stretch. The players wore blue wristbands, and the
uniforms of coaching staff, ball-boys, ball-girls, and grounds-crew
featured the blue ribb...
