Cancer Risks And Obesity

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 which explains obesity accounts for about 20% of all cancer cases.

Why does obesity increase cancer risk?

Extra fat in the body can have harmful effects, like producing hormones and growth factors that affect the way our cells work. This can raise the risk of several diseases, including cancer.

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 an 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:

  • Esophagus
  • Pancreas
  • Colon and rectum
  • Breast (after menopause)
  • Endometrium (lining of the uterus)
  • Kidney
  • Thyroid
  • Gallbladder

A report from the American Association for Cancer Research, also has evidence linking obesity to liver, cervix and multiple myeloma (cancer of plasma cells) cancers.

What can be done to prevent cancers linked to obesity?
