Thirty percent breast cancer caused by obesity

Up to a third of breast cancer cases could be avoided if women ate less and exercised more, researchers claim.
Experts believe more than 14,000 women a year would probably not develop the disease if they had adopted healthier behaviour from an early age.
Modern lifestyles which feature regular drinking, lack of exercise and increased obesity are fuelling the rise of the disease, reported dailymail.co.uk.
Research shows they are almost 50 percent more likely to die from breast cancer than women carrying fewer pounds.
It is unclear why obese women are more at risk, although changes in sex hormone levels triggered by weight gain could be behind oestrogen-dependent tumours, which form the majority of cases.
Studies show drinking one large glass of wine a day increases the chances of developing the disease by a fifth, say experts. Again, this could be linked to alcohol raising levels of oestrogen.
“The evidence is now convincing that drinking alcohol, being physically inactive and having excess body fat all increase risk of breast cancer,” said Rachel Thompson.
