How to Prevent Cancer or Find It Early

Cancer is the term used for diseases in which abnormal cells divide uncontrollably and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymphatic system. Cancer is not a single disease but many different diseases. There are more than 100 types of cancer.

Screening tests

Regular screening tests can detect breast, cervical, and colorectal (colon) cancers early, when treatment is usually most effective. Some people at high risk for lung cancer are recommended to get screened.

Vaccines (injections)

Vaccines also help reduce the risk of cancer. The human papillomavirus (HPV) vaccine helps prevent most cervical cancers and some vaginal and vulvar cancers. The hepatitis B vaccine can reduce the risk of liver cancer.

Healthy decisions

You can reduce your risk of getting cancer by making healthy choices like maintaining a healthy weight, avoiding smoking, limiting the amount of alcohol you drink, and protecting your skin from the sun.
