CANCER

WHAT IS CANCER?

Cancer is the name given to a set of related diseases. In all cancers, some of the body's cells begin to divide without stopping and spread to surrounding tissues.

Cancer can start almost anywhere in the body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When normal cells grow old or get damaged, they die, and new cells replace.

However, in cancer, this orderly process goes wrong. As the cells become more and more abnormal, old or damaged cells survive when they should die, and new cells form when not needed. These extra cells can divide without interruption and can form masses called tumors.

from my perspective, cancer is a very aggressive and silent disease because there are endless types of cancer, that sometimes most people do not realize now until the disease is present in your body.
