Lower your cancer risk in the following ways
You can reduce your risk of getting cancer in a variety of ways, including keeping a healthy weight, avoiding tobacco, limiting the amount of alcohol you drink, and protecting your skin.
Lung cancer is the leading cause of cancer death, and cigarette smoking causes almost all cases. Compared to nonsmokers, men who smoke are about 23 times more likely to develop lung cancer and women who smoke are about 13 times more likely. Smoking causes about 90% of lung cancer deaths in men and almost 80% in women. Smoking also causes cancer of the voicebox (larynx), mouth and throat, esophagus, bladder, kidney, pancreas, cervix, and stomach, and causes acute myeloid leukemia.1

Adults who are exposed to secondhand smoke at home or at work increase their risk of developing lung cancer by 20% to 30%. Concentrations of many cancer-causing and toxic chemicals are higher in secondhand smoke than in the smoke inhaled by smokers.2
Protecting Your Skin
Skin cancer is the most common form of cancer in the United States. Exposure to ultraviolet (UV) rays from the sun and tanning beds appears to be the most important environmental factor involved with developing skin cancer. To help prevent skin cancer while still having fun outdoors, protect yourself by seeking shade, applying sunscreen, and wearing sun-protective clothing, a hat, and sunglasses.

Limiting Alcohol Intake
Studies around the world have shown that drinking alcohol regularly increases the risk of getting mouth, voice box, and throat cancers. Daily consumption of around 50g of alcohol doubles or triples the risk for these cancers, compared with the risk in nondrinkers.3
A large number of studies provide strong evidence that drinking alcohol is a risk factor for primary liver cancer, and more than 100 studies have found an increased risk of breast cancer with increasing alcohol intake. The link between alcohol consumption and colorectal (colon) cancer has been reported in more than 50 studies.3

Keeping a Healthy Weight
Research has shown that being overweight or obese substantially raises a person's risk of getting endometrial (uterine), breast, prostate, and colorectal cancers. Overweight is defined as a body mass index (BMI) of 25 to 29, and obesity is defined as a BMI of 30 or higher.4 Learn how to choose a healthy diet at Healthy Eating for a Healthy Weight, and read about exercise at Physical Activity for a Healthy Weight.
Getting Tested for Hepatitis C
Hepatitis is inflammation of the liver, which is most often caused by a virus. In the United States, the most common type of viral hepatitis is hepatitis C. Over time, chronic hepatitis C can lead to serious liver problems including liver damage, cirrhosis, liver failure, or liver cancer. CDC recommends that anyone who was born between 1945 and 1965 get tested for hepatitis C.
