Breast cancer biology ‘changing’
ifestyle changes and screening have shifted the type of breast cancers women are diagnosed with over the past couple of decades, research suggests.

Women are now more likely to have hormone-dependent, slow-growing tumours, a comparison of tissue samples from the 1980s and 1990s shows.

The Scottish researchers also found improved survival over time, the British Journal of Cancer reported.

More than 40,000 women are diagnosed with breast cancer in the UK annually.

Previous studies have suggested that breast cancers may be more commonly hormone-dependent than in the past.
