The International Agency for Research on Cancer ( IARC) has just  published a report after reviewing published evidence, listing 13 cancers where there is sufficient evidence to conclude that being a healthy weight reduces the risk of cancer. A healthy weight is defined as having a Body mass Index ( BMI) of between 18.5 to 24.9. Many of the studies took into account other factors such as smoking, exercise and the healthy nature of the diet. The cancers identified are:

  • Oesophageal, stomach, bowel
  • Liver, gallbladder, pancreas
  • Breast, womb, ovarian
  • Kidney
  • Meningioma
  • Thyroid
  • Multiple myeloma

The IARC found evidence that sex hormones and inflammation are affected by weight and are involved in cancer formation.  Weight is not the only factor affecting the risk of cancer, other risk factors you have control over include:

  • Eat a health balanced diet
  • Stay physically active
  • Drink less alcohol
  • Stop smoking
  • Protect your skin from sun damage
