Two studies show how older breast cancer patients can be treated more effectively

Women with breast cancer who are aged older than 70 years are sometimes not offered surgery, chemotherapy or radiotherapy because doctors believe their patients will not be able to tolerate these treatments and will derive little benefit from them. These decisions may contribute to worse breast cancer survival rates for older women than for younger ones, although many older women will not benefit from more aggressive treatments and so may avoid harm from over-treatment.
