About 6,000 middle-aged or older women in the UK develop cancer each year because they are obese or overweight, a Cancer Research UK-funded study says. This is about 5% of such cases which looked at 45,000 cases of cancer in 1m women over seven years, according to the study.
The study is published online by the British Medical Journal. It is said that 50% of cases of womb cancer and a type of esophageal cancer were caused by excess fat. This heighten the link between cancer and weight which has been warned by an international study by the World Cancer Research Fund.
CANCERS LINKED TO OBESITY
- Multiple myeloma (bone marrow)
- Non-Hodgkin's lymphoma
The latest study looked at how often cancers occurred in 1.2m UK women aged 50 to 64 over a seven year period. More than 45,000 cases of cancer and 17,000 cancer deaths occurred during that time.
Lead researcher Dr Gillian Reeves, from Oxford University, said: "Two thirds of the additional 6,000 cancers each year due to overweight or obesity would be cancers of the womb or breast."
The research also found that the link between weight and risk of cancer depended on a woman's stage of life.
For example, being overweight increases the risk of breast cancer only after the menopause and the risk of bowel cancer only before the menopause.
This research has adds to the evidence regarding the effect of being overweight or obese on risk of developing cancer and dying from the disease. This also will associate being overweight directly of getting cancer. It is also clear now that lifestyle would impacts greatly on overall cancer risk.
"The message is clear. Invest in a healthier lifestyle today and we can reap the benefits of reduced disease risk and longer life tomorrow." said Dr Ian Campbell, the medical director of the charity Weight Concern.
