About Cancer


Cancer is a generic term used to describe a group of diseases that develop across time and can affect any part of the body. There are more than a hundred distinct types of cancer, which vary substantially in their behavior and response to treatment. Globally, cancer is the second leading cause of death and accounts for 9.6 million deaths in 2018.

As the cancer burden continues to grow globally, the prevention of cancer is one of the most significant challenges of the 21st century. To understand any cancer type and to manage it effectively, it is first important to understand about cancer.

What is cancer?

Humans are complex multicellular organisms made up of trillions of cells, each with its own structure and function. And our body is programmed to routinely replenish cells in different organs. As normal cells age or get damaged, they die off and new cells take their place as per the signals given by the genes.

Cancer begins when these genetic changes interfere with this orderly process. When this process is disturbed cells no longer respond to the signals and begin to grow abnormally. These abnormal cells grow and divide uncontrollably in the body and slowly accumulate to form a tissue mass, lump or growth called a tumor. These abnormal cells can destroy normal body tissue and spread through the bloodstream and lymphatic system.

Types of cancer

Cancers are mainly divided into five types based on where it begins:

  • Carcinomas develop in the skin or tissues that line the internal organs
  • Sarcomas begin in the bone, cartilage, fat, muscle or other connective tissues
  • Leukemia begins in the blood cells and bone marrow
  • Lymphomas begins in the lymphatic system
  • Central nervous system cancers develop in the brain and spinal cord
