You'll be fine! Get physio for chest issues....insist on CT scans of the masectomy site every ? couple of years or sooner? (also Pet scan)
I had a recurrence of cells around the pectoral muscle of my right side masectomy area (looked like lymphodema)....11 1/2 years after the first diagnosis/masectomy/chemo/radiation
The diagnosis was made when my tumor marker(blood) jumped from 35 to 45 (it had been climbing 1-2 points each year)...and the swelling got firmer/larger. Then I had an ultrasound/ core biopsy/CT scan... JANICE
