Cancer is a group of conditions where the body cells begin to grow and reproduce in an uncontrolled manner. These cells can then invade and destroy healthy tissues. The cells become cancerous or malignant because of DNA damage. This damage can be inherited, or can be caused by mistakes happening while normal cell is reproducing or by an environmental stimulus like tobacco. Cancer cells may travel to other parts of the body, where they begin to grow and form new tumors. This is known as metastases. It happens when cells get into blood stream or lymph vessels.

How Common is Cancer

Approximately 12, 00,000 new cancer cases are diagnosed in India every year. As per the latest National Cancer Registry data, one in eight men and one in nine women in India will develop some form of cancer. The incidence of cancer and cancer types are influenced by many factors such as age, sex, race, local environmental factors, diet and genetics. In males, lung followed by oral cavity and throat cancers are the most common, while cervical and breast cancers are the commonest ones diagnosed in females in India.

Types of Cancer

There are over 200 types of cancers, but most fit into the following categories:

  • Carcinoma – Cancer that begins in the skin or in tissues that line or cover internal organs.
  • Sarcoma – Cancer that begins in bone, cartilage, fat, muscles or other connective tissue.
  • Leukaemia – Cancer that starts in blood forming tissue such as bone marrow.
  • Lymphoma & Myeloma – Cancers that begin in the cells of the immune system.

  • Radiotherapy – It uses X-rays to destroy cancer cells.
  • Systemic Therapy – It uses drugs to destroy cancer cells and includes chemotherapy, targeted therapy and immunotherapy.

Cancer At A Glance

  • Cancer is the uncontrolled growth of cells anywhere in the body.
  • Unexplained weight loss, skin changes, changes in bowel habits, unusual bleeding, voice change, lumps are worrying signs & symptoms.
