I will try to answer your questions as honestly as I can and as clearly as possible.
Prostate cancer is one of the most common forms of cancer. More than 4 million men are living with prostate cancer. Men with prostate cancer have an increased risk of recurrence, and more men have prostate cancer when they are younger and have higher levels of a hormone called PSA, or prostate-specific antigen. PSA is found in the bloodstream and is a common marker for prostate cancer. PSA may also be used to assess if a patient has a cancerous lesion. There are different kinds of PSA, and some levels may be more dangerous than others. A person's level of PSA may fluctuate from month to month.
The doctors who do this work may use a prostate specific antigen (PSA) test, which is a blood test that measures a hormone called PSA. This hormone has been linked to a number of different cancers. However, the PSA test is usually done at a clinic that can refer a patient to a more specialized office. PSA is usually done in a biopsy, which means a sample is taken from the inside of the prostate.
