My mum was diagnosed with breast cancer in 1991 at the age of 60. She had a lumpectomy and radiotherapy, followed by tamoxifen treatment for five years. She was cancer free until 2003 when the cancer returned in the same breast. Stage 2. A single mastectomy followed and a little more radiotherapy - limited because she was close to the lifetime dose the first time round. She had some lymph glands removed from her neck and underarms which caused some problems with arm mobility, but after physiotherapy she was fine if a little restricted in movement. She’s now 91 and has had no recurrence. I hope this gives you some encouragement, and I wish you well with the surgery. As others have said, we’ll be holding your hand throughout and sending all the good vibes we can. Please come back and update us, and let us know how you’re getting on. You’re in my thoughts and prayers.?
