Is there is a link between BMI and cancer?

We know obesity has a link to high blood pressure, blood sugar issues and heart problems.

We know obesity has the potential to undermine our health.

A recent study has highlighted the link between cancer and BMI.

To understand more read on.

What was the aim?

To investigate the links between BMI and the most common site-specific cancers.

 What did they do?

  1. The investigated the associations between BMI and 22 of what they considered to be the most common cancers.
  2. 5·24 million individuals were included in the review.
  3. 166,955 people developed one of the 22 cancers they wanted to study.

What did they find?

  1. BMI was associated with 17 of 22 cancers, but the impact / effects of the cancer varied substantially by where they found the cancer.
  2. For each 5 kg/m2 increase in BMI, there was an increased risk of cancers of the uterus, gallbladder, kidney, cervix, thyroid and leukaemia.
  3. BMI was also associated with cancer of liver, colon, ovaries and post-menopausal cancers.

What did they conclude?

  1. “41% of uterine and 10% or more of gallbladder, kidney, liver, and colon cancers were due to excess weight.” (1)
  2. “BMI is associated with cancer risk.” (1)
  3. “For 1 kg/m2 population-wide increase in BMI there would be 3,790 people who developed one of the ten common cancers they found to be associated with BMI.” (1)

What is the bottom line?

Effective weight management is essential for long term health.  An eating plan that is characterised by moderation, variety, balance and anchored in a diet that is comprises approximately 70% fresh food is essential to support and promote optimal health.
