A large observational study published in the online journal, BMJ Open, has found that going up a skirt size over a period of 10 years between your mid 20s and mid 50s is linked to a 33% greater risk of developing breast cancer after the menopause.

The researchers based their findings on almost 93,000 women taking part in the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) in England.

Baroness Delyth Morgan, Chief Executive at Breast Cancer Campaign, says:

“This study confirms some of what we already know about how obesity can impact on a woman’s breast cancer risk. Whilst the results of the study still need to be validated, we believe that anything that helps women better understand their personal risk of breast cancer is a good thing so they can take action to lower this risk. We know that women can reduce their risk of breast cancer by up to 30% by taking steps such as maintaining a healthy weight throughout life, reducing alcohol intake and following the recommended levels of physical activity.”
