Prostate Cancer Foundation

Cancer starts gone cells in the body begin to build up out of control. Cells in approximately any share of the body can become cancer cells, and can further to further areas of the body. To learn more not quite how cancers start and spread, look What Is Cancer?

Prostate Cancer Foundation

Prostate cancer begins similar to cells in the prostate gland begin to amass uncontrollably. The prostate is a gland found forlorn in males. It makes some of the fluid that is part of semen.

The prostate is below the bladder and in stomach of the rectum. The size of the prostate changes in the same way as age. In younger men, it is approximately the size of a walnut, but it can be much larger in older men.

Just astern the prostate are glands called seminal vesicles that make most of the fluid for semen. The urethra, which is the tube that carries urine and semen out of the body through the penis, goes through the middle of the prostate.

Types of prostate cancer

Almost all prostate cancers are adenocarcinomas. These cancers produce from the gland cells (the cells that create the prostate nebulous that is extra to the semen).

Other types of prostate cancer include:

Sarcomas
Small cell carcinomas
Neuroendocrine tumors (other than small cell carcinomas)
Transitional cell carcinomas
These extra types of prostate cancer are rare. If you have prostate cancer it is in relation to positive to be an adenocarcinoma.

Some prostate cancers can be credited with and further quickly, but most accumulate slowly. In fact, autopsy studies perform that many older men (and even some younger men) who died of new causes as well as had prostate cancer that never affected them during their lives. In many cases neither they nor their doctors even knew they had it.

Possible pre-cancerous conditions of the prostate

Some research suggests that prostate cancer starts out as a pre-cancerous condition, although this is not still known for sure. These conditions are sometimes found taking into account a man has a prostate biopsy (removal of small pieces of the prostate to see for cancer).

Prostatic intraepithelial neoplasia (PIN)

In PIN, there are changes in how the prostate gland cells see under a microscope, but the unusual cells dont look later they are growing into supplementary parts of the prostate (like cancer cells would). Based on how uncharacteristic the patterns of cells look, they are classified as:

Low-grade PIN: the patterns of prostate cells appear around normal
High-grade PIN: the patterns of cells look more abnormal
PIN begins to appear in the prostates of some men as before as in their 20s.

Many men begin to develop low-grade fix taking into consideration they are younger but dont necessarily produce prostate cancer. The attainable member in the company of low-grade glue and prostate cancer is nevertheless unclear.

If high-grade glue is found in your prostate biopsy sample, there is more or less a 20% fortuitous that you afterward have cancer in unusual area of your prostate.

Proliferative inflammatory atrophy (PIA)

In PIA, the prostate cells look smaller than normal, and there are signs of inflammation in the area. PIA is not cancer, but researchers receive that PIA may sometimes lead to high-grade PIN, or perhaps to prostate cancer directly.
