Q:
A friend recently told me that being obese can cause certain cancers. Is this true?
A:
Obesity presents a significant risk factor with regard to a wide array of medical issues, including cancer. We are discovering a strong correlation between excess weight (overweight and obese) and a higher risk of various cancers.
In the U.S., obesity has been implicated in roughly 14% of cancer deaths in men and 20% in women. Obese men have a greater risk of developing cancer of the esophagus, liver, pancreas, colon, and prostate. Obese women are more likely to have cancer of the breasts, gallbladder, bile ducts, ovaries, cervix and endometrium.
There are undeniable parallels between obesity and cancer. The higher a person's BMI* climbs, the greater the chance of developing cancer. This alarming connection can be partially explained by the hormonal changes and genetic predisposition of these individuals. Nonetheless, we have much more to learn about this relationship.
Ultimately, our goal should be to focus on how to stop obesity and thus cut the risk of preventable cancers. Better lifestyle choices are essential in reversing the obesity trend. Key factors include an optimal diet (high fiber, low fat, low calorie), reducing alcohol intake, and consistent daily exercise habits. See your physician for more information regarding healthy lifestyle choices and early cancer screening.
