What is prostate cancer

Prostate cancer is a malignant growth of the glandular cells of the prostate. Our body is composed of billions of cells; they are the smallest unit in the body. Normally, each cell functions for a while, then dies and is replaced in an organized manner. This results in the appropriate number of cells being present to carry out necessary cell functions. Sometimes there can be an uncontrolled replacement of cells, leaving the cells unable to organize as they did before. Such abnormal growth of cells is called a tumor. Tumors may be benign (noncancerous)

or malignant (cancerous). Cancer is abnormal cell growth and disorder such that the cancer cells can grow without the normal controls and limits. A malignancy is a cancerous growth that has the potential to spread and cause damage to other tissues of the body or even lead to death. Cancers can spread locally into surrounding tissues, or cancer cells can break away from the tumor and enter body fluids, such as the blood and lymph, and spread to other parts of the body. Lymph is an almost clear fluid that drains waste from cells. This fluid travels in vessels to the lymph nodes, small bean-shaped structures that filter unwanted substances, such as cancer cells and bacteria, out of the fluid. Lymph nodes may become filled with cancer cells.

As with most cancers, prostate cancer is not contagious.
