There is research suggesting the impact obesity has on the development of certain cancers. According to Sir Richard Doll and Richard Peto, 35% of cancer deaths in the USA might be linked to diet. This is particularly certain for endometrium and breast cancer. The Washington School of Medicine submitted a document that explains obesity accounts for about 20% of all cancer cases.
8 Proven Cancer Risks And Obesity
Why does obesity increase cancer risk?
Among those harmful effects are:
- Increased levels of insulin and insulin growth factor-1, which may help some cancers develop.
- Chronic, low-level inflammation, which is more common in people who are obese and is linked with increased cancer risk.
- Higher amounts of estrogen produced by fat tissue, which can drive the development of some cancers, such as breast and endometrial cancers.
- Fat cells may also affect processes that regulate cancer cell growth.
What cancer types are linked to obesity?
Among the known types of cancer are:
- Colon and rectum
- Breast (after menopause)
- Endometrium (lining of the uterus)
A report from the American Association for Cancer Research also has evidence linking obesity to the liver, cervix, and multiple myeloma (cancer of plasma cells) cancers.
What can be done to prevent cancers linked to obesity?
Follow a healthy eating plan. Take into account your calorie needs and those of your family.
Take into account the portion size of the food you eat. The calorie intake should not surpass your body’s daily needs. Consult your physician to help you know what is your recommended daily calorie intake.
Be active. According to the Mayo Clinic, 30 minutes a day of physical activity are recommended if you wish to keep your current body weight. However, if you are currently overweight, you should consult your physician for a personalized plan.
