Male reproductive system. PSA test is used to detect prostate cancer.
to diagnose whether prostate cancer has spread to other parts of the body (metastasized), and to check the effectiveness of treatment. The test has been largely supplanted by the prostate specific antigen test (PSA)
when a antigen enters the body then the body would send antibodies to get rid of them. The antibody doesn't get rid of the antigen they tag it by binding to it so that a cell..a white blood cell can come and destroy by phagi.
An antibody is a protein that acts against a specific antigen by binding to it and marking it for destruction by the immune system. Antibodies are produced by B cells in response to the presence of foreign substances in the body.
When an antigen and its matching antibody meet in the body, the antibody binds to the antigen, marking it for destruction by the immune system. This process helps to neutralize the antigen and prevent further harm to the body.
Antigen is a component of the immune system. It can trigger an immune response in the body by interacting with antibodies or immune cells.

As a general term "cancer" means that some abnormal cells are present in a particular part of your body. All the cells of our body have their own "program" to live, but cancer cells do not follow this program. The same happens with prostate cancer, it is characterized by the presence of abnormal prostate cells (cancer cells), causing the damages to prostate and other symptoms. These cells are capable to multiply very fast, increasing their number and the tumor size. Because of this, the normal prostate cells are suppressed and cannot function properly. When a man has prostate cancer, his PSA (prostate specific antigen) levels will rise. In many cases of prostate cancer, the prostate gland is removed.
An Immunogen is foreign particle that triggers the body's immune system where as Antigen is also a foreign particle , due to its low molecular weight it is unable to trigger immune system. Example for antigen is Hapten
An antigen may be made of either a bacteria or a virus. An antigen refers to a toxic or a foreign substance that once in the body attracts and is bound to a respective and specific antibody.
Vaccination introduces foreign antigen and the body responds by producing antibodies for that specific antigen. So overall levels of antibody may not considerably increase, but antibodies specific for that antigen will increase dramatically.
Prostate metastasis is when cancer cells in the prostate get into the lymph system and begin to travel to other organs of the body, spreading the cancer.
