Cancer is a disease that results from abnormal growth and division of cells that make up the body’s tissues and organs. Under normal circumstances, cells reproduce in an orderly fashion to replace old cells, maintain tissue health and repair injuries.
However, when growth control is lost and cells divide too much and too fast, a cellular mass -or “tumor” -is formed.
If the tumor is confined to a few cell layers and it does not invade surrounding tissues or organs, it is considered benign. By contrast, if the tumor spreads to surrounding tissues or organs, it is considered malignant, or cancerous. In order to grow further, a cancer develops its own blood vessels and this process is called angiogenesis. When it first develops, a malignant tumor may be confined to its original site.
If cancerous cells are not treated they may break away from the original tumor, travel, and grow within other body parts, the process is known as metastasis.
Cancer Screening is the performance of tests on apparently well people in order to detect a medical condition at an earlier stage.
