Obesity and Cancer: What You Need to Know

Obesity is a significant risk factor for many chronic diseases, including cancer. Obesity is linked to about 4% to 8% of all cancers diagnosed annually in the United States. But is this message being communicated to patients?

There are several ways that obesity can increase your risk of cancer. One way is through inflammation. Excess body fat produces pro-inflammatory molecules that can damage cells and DNA, leading to cancer. Obesity can also disrupt hormone levels, which can further increase cancer risk. For example, women who are obese are more likely to develop breast cancer after menopause when their estrogen levels are higher.

The following are some of the types of cancer that are linked to obesity:

  • Colorectal cancer: Obesity is the leading cause of colorectal cancer in the United States.
  • Breast cancer: Obesity is a risk factor for breast cancer, especially in postmenopausal women.
  • Endometrial cancer: Obesity is a significant risk factor for endometrial cancer, which is cancer of the lining of the uterus.
  • Kidney cancer: Obesity is a risk factor for kidney cancer, especially in men.
  • Esophageal cancer: Obesity is a risk factor for esophageal cancer, especially adenocarcinoma.
  • Pancreatic cancer: Obesity is a risk factor for pancreatic cancer, especially in men.
  • Liver cancer: Obesity is a risk factor, especially in people with hepatitis or cirrhosis.
  • Gallbladder cancer: Obesity is a risk factor for gallbladder cancer, especially in women.

If you are obese, there are things you can do to lower your risk of cancer. These include:

  • Losing weight. Even a tiny amount of weight loss can make a difference.
  • Eating a healthy diet. This includes plenty of fruits, vegetables, and whole grains.
  • Exercising regularly. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
  • Not smoking. Smoking is a major risk factor for cancer, and quitting can lower your risk.

If you are concerned about your risk of cancer, talk to your doctor. They can help you assess your risk and develop a plan to reduce it.

Does obesity affect survival rates in cancer patients as well?

Yes, obesity can affect survival rates in cancer patients. Studies have shown that obese cancer patients are more likely to die from their cancer than non-obese patients. This is likely due to several factors, including the fact that obese patients are more likely to have aggressive cancers and are less likely to respond to treatment.

Does losing weight decrease cancer risk?

Yes, losing weight can decrease cancer risk. Even a tiny amount of weight loss can make a difference. Studies have shown that people who lose weight are less likely to develop cancer and more likely to survive if they do develop cancer.

If you are obese and concerned about your cancer risk, talk to your doctor about ways to lose weight safely and effectively. Losing weight can help you improve your overall health and lower your risk of developing cancer.

Every patient who is obese should receive literature from their HCP on the increased risk for cancer(s).
