How did I get prostate cancer?
A common question a patient asks. We have no easy answers but we have some possibilities to offer. Cells in the body are constantly dividing, salve reaching maturity and dying in a controlled programmed manner. The process is called apoptosis. If the process gets screwed up and stops, viagra cells that should die off don’t and they continue to proliferate uncontrolled. That’s when they lump together and form a tumor. The tumor can then spread and invade other sites in the body.
Prostate cancers typically begin in the part of the prostate gland that is closest to the rectum. When a tumor reaches the size of about 1 cm, the doctor can perform a DRE (digital rectal exam) and detect the presence of the tumor. The next step is a biopsy to confirm the finding. That was the principle test until 1986. That’s when the PSA test was inaugurated. Today, the PSA test can detect elevated levels of prostate-specific antigen—signaling presence of a tumor—well before the tumor has grown to a size that can be felt during a DRE.
While researchers are homing in on the causes of prostate cancer, they can already point to critical risk factors for influencing whether or not cancer will develop. They include age, race and family history.
