Breast cancer self checks questioned by Glasgow GP

A Glasgow GP has criticised The Sun's breast cancer awareness campaign, claiming that self-checking could do "more harm than good".
Dr Margaret McCartney said an international study showed women who self-checked were more likely to have biopsies on benign tumours and consequently suffer stress and anxiety.
Speaking to BBC Radio 5 live's Victoria Derbyshire, Dr McCartney said women often found lumps that were not "useful" and were put through tests that would not benefit them.
Kris Hallenga, founder of the CoppaFeel charity who ran the campaign with the Sun, told the programme the advice was "dangerous" and regular checks would help women catch cancer earlier.
