Lifelong excess weight can double the risk of womb cancer: study


A new study by scientists in the UK has found that lifelong excess weight nearly doubles a woman’s risk of developing womb cancer. The study, which has been published in the journal BMC Medicine, was conducted by researchers at the University of Bristol.

The researchers analysed samples from some 120,000 women from Australia, Belgium, Germany, Poland, Sweden, the UK and the USA, and found that for every five extra body mass index (BMI) units, a woman’s risk of endometrial cancer increases by 88%. A BMI of 18 to 25 is considered a healthy weight, 25 to 30 is overweight, and over 30 is considered obese.

They looked at markers of 14 traits that could link obesity and womb cancer and found that fasting insulin and testosterone hormones increased the risk of womb cancer, which affects one in 36 UK women in their lifetime.

The researchers believe that by identifying how these hormones increase the risk of getting womb cancer, scientists will be able to come up with drugs to regulate the levels of these hormones.
