Hello, my mother has found a small  breast cancer two years ago. She had
mastectomy and she was told it was discovered at an early stage because
its stage was t1bn0m0. She had to have a chemo treatment anyway. After
5/6 month there has been a local recurrence, she had another chemo and a
radiation therapy. Unfortunately now she has another local recurrence
and she is very doubt full to have another chemo treatment as her
oncologist suggested. She is worried by the fact all recurrences appear
 in a so short time, 3/5 month max, after she has finished treatments
that seem to have no  effect.
Is it common to have so many recurrences in a so short time after all
these treatments?
Thank you to all.
