Lifestyles are important factors in the formation of many types of cancer. Behavior and choice can affect cancer risks. But when it comes to individual cancers it is not possible to say for sure what causes the cancer.
We can lessen the risk of getting cancer, but as yet there is not enough known about preventing cancer completely.
Healthy lifestyles help reduce risk of cancer. Everyone should exercise regularly and have a varied diet. People need to eat plenty of plant products and fiber, and only very little red meat and saturated fat. Things to avoid are smoking, drinking and too much exposure to the sun.
You can take better care of yourself too by having regular medical check-ups and take part in organized cancer screenings.
