A medical study in the UK has found that 19 per
cent of breast cancers diagnosed would not
have been harmful if left undiagnosed and
untreated.
This could lead to healthy women having
treatments like surgery, radiotherapy and
chemotherapy which have considerable side-
effects.
However, the independent panel also found that
routine breast screening leads to a 20 per cent
reduction in relative risk compared to no
screening.
This means that one death through breast
cancer being prevented for every 235 women
invited for screening.
