The number of cases of womb cancer in the UK has reached a 30-year high.
This is according to a study conducted by Cancer Research UK, which revealed that more than 7,530 people develop the disease every year.
Jessica Harris, a health information officer for the group, said: "The risk factors for womb cancer that we know about at the moment are mostly about the levels of different hormones in your body and the balance of the different hormones."
She added: "When levels of oestrogen in your body are higher and progesterone is lower, it still lets the cells in the womb grow, and that happening over a long period of time can lead to an increase of womb cancer."
Hormonal changes in overweight or obese women could be responsible for the high number of cases, as could a drop in the number of pregnancies, experts at the charity suggested.
