Cancer: The abnormal proliferation of cells

Cancer is not a single disease but a group of diseases, that share a fundamental feature ‘the abnormal proliferation of cells‘. Cancer or malignancy can be defined as an uncontrolled cell division that can infiltrate the neighboring tissues. The cancerous cells may also spread to other parts of the body; either through the blood or lymphatic system.


  • Carcinoma begins in the skin or in the tissues, which either line or covers internal organs.
  • Sarcoma starts in bones, cartilage, muscle, fat, or any other connective or supportive tissue.
  • Leukemia begins in blood-forming tissue causing a large number of abnormal blood cells that enter the blood flow.
  • Lymphoma and multiple myelomas are cancer that starts with the immune system. Read more about Lymphoma: Symptoms, Causes, Diagnosis, Treatment
  • Central nervous system cancer begins in the tissues of the brain and the spinal cord.

    1. According to India Against Cancer, Over 2.25 million people in India are living with cancer. A study published in the Journal of Global Oncology says that this number could double by 2040. Lifestyle-related cancers like lung cancer are overtaking infectious cancers like cervical cancer. These statistics make cancer research paramount as the number of cancer patients has increased many folds and treatment is still not satisfactory, especially in advanced stages.

    1. Cancer can occur irrespective of age. Even a child as young as a year can develop cancer but usually, older adults are at higher risk of developing cancer. The cell damage at times is checked by our body but in few of the cases, the cell damage can lead to abnormal growth and proliferation of cells causing cancer.
      Irrespective of age leading a healthy lifestyle and preventing exposure to oncogenes helps to prevent the development of cancer. Things like exposure to the sun for a long time, smoking tobacco, exposure to radiation, exposure to certain chemicals. Keeping active and fit helps to prevent cancer.
