A growing body of research suggests that many cancer cases—and deaths—may be more preventable than we realize. According to a comprehensive study from the American Cancer Society, nearly 40% of cancer diagnoses and 50% of cancer-related deaths in U.S. adults over 30 are linked to modifiable risk factors—choices and habits we can change.
The top contributors?
- Smoking – responsible for almost 30% of all cancer deaths.
- Excess body weight
- Alcohol consumption
These findings underscore the powerful impact of lifestyle on long-term health. Dr. Molly Meyers, a colon and rectal surgeon at Aurora Health Care, emphasizes, “Making improvements to your lifestyle can absolutely lower your risk of being diagnosed with cancer.”
Here are some practical steps to take:
- Quit smoking and avoid all forms of nicotine. Seek support if needed—this is the single most effective way to cut your cancer risk.
- Get moving. Regular physical activity not only helps control weight but also reduces inflammation and strengthens immunity.
- Eat whole foods. Focus on fruits, vegetables, lean proteins, and whole grains while minimizing processed and sugary foods.
- Limit alcohol or avoid it entirely. Even moderate drinking has been linked to certain cancers.
- Talk to your doctor. Schedule regular checkups to review your weight, discuss risk factors, and consider vaccinations like HPV and hepatitis B, which help prevent virus-related cancers.
While cancer can’t always be avoided, many cases are preventable with consistent, intentional choices. By prioritizing your health today, you’re investing in a healthier future.
