It takes effort to keep fit, but when I read stories like this it reminds me it's worth it.
Scientists have run the largest ever study, involving 5 million people, to look at the link between obesity and cancer. It's hardly news that being overweight is linked to health risks, but now doctors find that specific types of cancer depend on how overweight someone is.
Cancers linked to obesity include those of the uterus, gall bladder, kidney, cervix, thyroid and also leukaemia. Expert advice, as always, is to exercise regularly and eat healthily.
