Researchers from Harvard Medical School looked at 89,571 Caucasian women and 46,399 Caucasian men to see how much a healthy lifestyle could reduce cancer risk.
16,531 women and 11,731 men had a healthy lifestyle pattern and were determined to be low risk. These healthy patterns included moderate or no drinking, a BMI between 18.5 and 27.5, weekly physical activity that included at least 150 minutes of moderate intensity or 75 minutes of vigorous intensity, and either never having smoked or currently not being a smoker.
The authors then studied cancer rates among the high- and low-risk groups. They found that overall, 20 percent to 40 percent of carcinoma cases and about half of carcinoma deaths can be potentially prevented through lifestyle modification. Carcinomas form in the lining of certain tissues or organs and is the most common form of cancer.
"We have no other option. We have to work on prevention more than treatment. Just a thought.
