Detection of prostate cancer by blood test

 WHAT IS PROSTATE?
The prostate gland sits just below the bladder and in front of the rectum, partially surrounding the urethra which carries urine from the bladder out of the body. Forming part of the male reproductive system, the prostrate is responsible for the production of a clear liquid which makes up about one third of the seminal fluid used to carry and protect the male sperm during intercourse.




WHAT IS PROSTATE CANCER?
Prostate cancer is cancer that starts in the prostate gland. The prostate is a small, walnut-sized structure that makes up part of a man's reproductive system. It wraps around the urethra, the tube that carries urine out of the body.

SYMPTOMS OF PROSTATE CANCER?

* Dribbling or leakage of urine, most often after urinating

* Slow urinary stream

* Straining when urinating, or not being able to empty out all of the urine

* Blood in the urine or semen

* Bone pain or tenderness, most often in the lower back and pelvic bones (only when the cancer has spread)


NEW BLOOD TEST FOR DETECTING PROSTATE CANCER
A new blood test is more reliable at finding prostate cancer in its early stages by detecting a protein marker in blood plasma. Doctors say the new test, now in clinical trials, will have an accuracy of 95 percent, better than the commonly used PSA, which signals abnormal prostate conditions rather than cancer.
