Obesity - defined as having a body mass index (BMI) of 30 or higher - is a major problem in the US, affecting more than a third of adults and almost a fifth of children and adolescents. If this study is right it's a huge increase.
Women who are obese are around 40% more likely to develop certain forms of cancer than those of a healthy weight. This is according to new estimates calculated by Cancer Research UK.
Obese women are at a 41% higher lifetime risk of developing a weight-related cancer than women of a healthy weight, the new statistics show.

It is well established that obesity can increase cancer risk. According to the American Cancer Society, excess body weight may contribute to cancer development through a number of mechanisms. It can interfere with immune system function, for example, or affect levels of hormones - such as estrogen and insulin - to drive cancer development.
The following shows the increased lifetime cancer risk for obese women by cancer type, compared with women of a healthy weight:
Breast cancer (postmenopausal) - 25%
Pancreas cancer - 31%
Bowel cancer - 32%
Kidney cancer - 78%
Gallbladder cancer - 100%
Uterus (endometrium) cancer - 131%
Esophageal cancer - 133%.
