Here are some key tips for improving our odds of living cancer-free:

• Quit tobacco in all its forms: There’s no secret here that smoking and other tobacco use is the leading risk for cancer and other serious diseases. Cigarette smoking alone is believed to cause about 30 percent of cancer deaths in the U.S.

• Get vaccinated: Certain viruses and bacteria can cause cancer in humans. But there are vaccines approved for use in protecting against infection two such viruses – the human papillomavirus (HPV), which can cause cervical cancer, and hepatitis B.

• Drink in moderation: Studies have linked alcohol use to an increased risk of certain cancers. Men are encouraged to limit their drinking to two drinks a day, and women to one drink a day.

• Maintain a healthy weight: Obesity has been linked to a number of cancers, and being overweight may cause the body to produce more estrogen and insulin, two hormones that can stimulate cancer growth.

• Avoid UV rays: The ultraviolet radiation in sunlight is the leading cause of skin cancers. Take steps to avoid exposure by covering up and using sunscreen with an SPF of 15 or higher.

• Get screened: Common cancer screenings, such as mammograms, colorectal screenings, PAP tests, and prostate exams, lead to early identification and treatment.

These tips, along with staying physically active and eating a healthy diet with a focus on plant-based foods, are our best defense in the fight against cancer.
