Women with excessive abdominal fat are at risk of developing a type of breast cancer that is harder to treat compared with those who have general obesity or widespread fat accumulation, a study suggests.

Researchers in China examined medical data of 1,316 women aged 25-70 from 21 hospitals across the country who had been recently diagnosed with breast cancer.

They took body measurements and information on whether the women had been diagnosed with oestrogen-receptor positive (ER+) or the harder to treat negative (ER-) cancer.

Women with a high body mass index, providing a measure of subcutaneous fat on the thighs, hips and buttocks, were more likely

Women with excessive abdominal fat are at risk of developing a type of breast cancer that is harder to treat compared with those who have general obesity or widespread fat accumulation, a study suggests.

Researchers in China examined medical data of 1,316 women aged 25-70 from 21 hospitals across the country who had been recently diagnosed with breast cancer.

They took body measurements and information on whether the women had been diagnosed with oestrogen-receptor positive (ER+) or the harder to treat negative (ER-) cancer.

Women with a high body mass index, providing a measure of subcutaneous fat on the thighs, hips and buttocks, were more likely to have ER+ breast cancers.

In contrast, women with a high waist-hip ratio, providing a measure of visceral fat (stomach and internal organs), were more likely to have ER- breast cancer.
