Breast screening saves lives, say experts
14. 07. 2009 | Cancer Research UK
UK screening experts have emphasised the benefits of breast screening after a study suggested that one in three cancers detected by screening might not need treatment.
Researchers at the Nordic Cochrane Centre have claimed that up to one in three cases of breast cancer detected during routine screening may not threaten a woman's life, and would not need treatment.
Some breast cancers grow slowly, lie dormant or even regress - treating women with these tumours amounts to 'over-treatment'. However it is currently impossible to tell which tumours are aggressive and which are less harmful, so doctors offer treatment to most women.
