Lets Undertand What Cancer Is?

Know the Signs. Understand the Risks. Take Action.

Cancer is a group of diseases in which abnormal cells grow uncontrollably and may spread to other parts of the body. It can develop in almost any part of the body, and different types of cancer can have different causes, symptoms, and treatments.

How Can Cancer Develop?

Cancer develops when changes occur in the genes that control how cells grow and divide. These changes can happen naturally as cells divide, be inherited, or result from certain environmental exposures and risk factors. Tobacco use, UV radiation, some infections, alcohol use, and other factors can increase the risk of certain cancers.

Know the Warning Signs

Symptoms vary depending on the type of cancer. Possible warning signs can include:

  • Unexplained weight loss or severe, persistent fatigue

  • New lumps or swelling

  • Unusual bleeding or bruising

  • Persistent cough or hoarseness

  • Changes in bowel or bladder habits

  • Changes in a mole or skin lesion

  • Persistent pain or other unexplained changes

These symptoms can have many causes besides cancer. If something unusual persists for several weeks or concerns you, speak with a healthcare professional.

Awareness Can Make a Difference


Learning about risk factors, recognizing unusual changes, and seeking medical advice when needed can help people take informed steps toward their health.


Stay informed. Listen to your body. Talk to your healthcare provider.
