Cancer Linked To Weight

Here is another reason we need to eat correctly and watch our weight. According to an article written by Jasmin Malik Chua, a Live Science Contributor, 40% of cancer cases in the US are liked to weight.

There are at least 13 types of cancer which will increase a person’s risk by being overweight or obese.

These include:

  • The Brain
  • Esophagus
  • Thyroid
  • Gallbladder
  • Stomach
  • Pancreas
  • Kidney
  • Uterus
  • Colon

The report was published by the Centers for Disease Control and Prevention where they found that in 2014 alone, more than 630,000 people in the US had a type of cancer that was associated with being overweight or obese.  This amounted to more than 55% of all cancers that were diagnosed among women and 24% among men.  The relationships between a higher body mass index (BMI) and chronic conditions such as diabetes and cardiovascular disease are well known, but the researchers know much less about how a higher body weight might be linked to certain cancers.

Dr. Anne Schuchat, deputy director of the CDC said that awareness of some cancers being associated with obesity and being overweight is not yet widespread.  The cancer agency of the World Health Organization, The International Agency for Research on Cancer, says that there is sufficient evidence to link excess body fat to at least the 13 different cancers listed above.  The excess weight might also increase levels of certain hormones such as insulin and sex hormones which play a role in growth that have been linked to cancer risk.

Weight related cancers were increasingly being diagnosed among younger people.  There was a 1.4% rise in cancers related to being overweight and obese among people ages 20 to 49, compared to a 0.4% increase in these cancers among the 50 to 64 set.  Nearly 1/2 of all cancers in people younger than 65 were associated with excess weight.

Those who are overweight or obese are also about 30% more likely to develop colorectal cancer than those with a normal weight, and overweight women are about 2 to 4 times more likely to develop endometrial cancer.

Comprehensive cancer control strategies, including use of evidence based interventions to promote healthy weight could help to decrease the incidence of these cancers in the US.
