Prostate cancer is a group of cancerous cells (a malignant tumor) that begins most often in the outer part of the prostate. It is the second most common type of cancer in men in the United States. Skin cancer is the most common. Of all the men who are diagnosed with cancer each year, more than one-fourth have prostate cancer.prostate basics
The prostate is a gland in a man's reproductive system. It makes and stores seminal fluid, a milky fluid that nourishes sperm. This fluid is released to form part of semen.
The prostate is about the size of a walnut. It is located below the urinary bladder and in front of the rectum. It surrounds the upper part of the urethra, the tube that empties urine from the bladder. If the prostate grows too large, the flow of urine can be slowed or stopped.
To work properly, the prostate needs male hormones (androgens). Male hormones are responsible for male sex characteristics. The main male hormone is testosterone, which is made mainly by the testicles. Some male hormones are produced in small amounts by the adrenal glands.early symptoms - prostate cancer
Early symptoms of prostate cancer are often difficult to trace, as prostate cancer does not cause unique symptoms. But prostate cancer can cause any of these problems:
Any of the above listed "prostate cancer symptoms" may be caused by cancer or by other, less serious health problems, such as BPH or an infection. A man who has "prostate cancer symptoms" like these should see his doctor or a urologist (a doctor who specializes in treating diseases of the genitourinary system).understanding the cancer process
Cancer is a group of many related diseases. These diseases begin in cells, the body's basic unit of life. Cells have many important functions throughout the body.
Normally, cells grow and divide to form new cells in an orderly way. They perform their functions for a while, and then they die. This process helps keep the body healthy.
Sometimes, however, cells do not die. Instead, they keep dividing and creating new cells that the body does not need. They form a mass of tissue, called a growth or tumor.tumors can be benign or malignant:
When prostate cancer spreads (metastasizes) outside the prostate, cancer cells are often found in nearby lymph nodes. If the cancer has reached these nodes, it means that cancer cells may have spread to other parts of the body -- other lymph nodes and other organs, such as the bones, bladder, or rectum. When cancer spreads from its original location to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary tumor. For example, if prostate cancer spreads to the bones, the cancer cells in the new tumor are prostate cancer cells. The disease is metastatic prostate cancer; it is not bone cancer.
