Obesity increases the risk of some types of cancer.
There is strong evidence that obese women are at increased risk for cancer of the uterus (womb).
Women who have been through the menopause and are obese or overweight have a greater risk of developing breast cancer.
There is also some evidence for a link between obesity and cancer of the bowel and kidney.
Even if you are happy with your weight, eating well and taking regular exercise will improve your health.
