It is now clear that radiotherapy saves lives in women who have had breast-conserving surgery and in women whose cancer has substantial spread to the armpit, even if they have already had a mastectomy. This should encourage women who are offered radiotherapy to go ahead and have the treatment. It may also encourage doctors to consider more women for radiotherapy than they have done in the past.
