Cancer Prevention Overview (PDQ®): Prevention - Patient Information [NCI] - What is Prevention?

Cancer prevention is action taken to lower the chance of getting cancer. By preventing cancer, the number of new cases of cancer in a group or population is lowered. Hopefully, this will lower the number of deaths caused by cancer.

Cancer is not a single disease but a group of related diseases. Many things in our genes, our lifestyle, and the environment around us may increase or decrease our risk of getting cancer.

Scientists are studying many different ways to help prevent cancer, including the following:

  • Ways to avoid or control things known to cause cancer.
  • Changes in diet and lifestyle.
  • Finding precancerous conditions early. Precancerous conditions are conditions that may become cancer.
  • Chemoprevention (medicines to treat a precancerous condition or to keep cancer from starting).
