hi, my mom has had
breast cancer for 3 years, she was diagnosed with stage3, first surgery took the tumor and all limp nods from right arm, 1 year later breast cancer came back next to first scare, so they the took the whole breast, now 1 year as of april, she is having a biopsy done to her right lung do to nodules found a nd growing larger quickly, my question is, is this cancer again? is it rare?
