Knowledge of how your body normally works can help you be aware of changes that may be caused by cancer. It is important to talk to your doctor if you develop any inexplicable or unusual symptoms.

Certain symptoms must always be brought to the attention of a qualified physician. The earlier cancer is detected, the more likely it can be cured.

The most common symptoms include:

  • unexplained bleeding
  • unexplained weight loss
  • lump or swelling
  • unexplained pain

These symptoms may caused by something other than cancer. However, it is always best to consult with a doctor as soon as possible.


If you notice any unusual symptoms or changes to your body, talk to your doctor. Many symptoms are caused by conditions that are not related to cancer. Nonetheless, early detection of cancerous growths may make for easier treatment.

Try to keep your sense of worry from preventing you from seeing a doctor. Consult with your doctor if any symptoms persist for longer than two weeks. This includes:

  • A bump on any part of the body.
  • Coughing or hoarseness lasting longer than three weeks.
  • Any change in bowel habits lasting longer than six weeks.

Any abnormal bleeding of the vagina or intestine or blood in the urine or in vomit.
