What is Prostate Cancer?


What is prostate cancer? The term cancer refers to a very large group of what-is-prostate-cancerdifferent diseases, which all have one thing in common: the uncontrolled cell division of an organ or tissue. These uncontrolled cells form what is known as a tumor. Prostate cancer occurs when the prostate develops this kind of a tumor.

Malignant tumors are characterized by the fact that they grow abnormally and out of control. The modified cells proliferate unabated. They can grow into surrounding tissue and destroy it, and spread into other parts of the body through the blood and lymphatic vessels. Once there, they can settle and multiply again. This spreading of cancer from one organ to another is called metastasis.

Today, we know that the reason for the emergence of cancer is a change in the genetic material of cells that causes abnormal growth. In general, there are many factors, both external and internal, that work together to cause a cell to become cancerous. The final part of this process of damage and disruption is always a change in the gene control of cell growth, which leads to unregulated cell division and normal functional cell properties. In some cases the risk of developing cancer can be inherited, possibly including some forms of prostate cancer.

Some external influences which can be a trigger for the development of cancer include:

- Tobacco smoke
- Ultraviolet rays from the sun
- Radiation
- Certain molds on food
- Malnutrition
- Some viral infections
- Certain chemicals

These alone however can not alone be held responsible for the development of cancer. Diet also plays a role in prostate cancer.

Age is another reason that cancer develops more often in older people, due to the reduction in cell repair capabilities that go along with the aging process. Prostate cancer usually only occurs during old age.
