Hi it’s been nearly a year since I finished all my treatment( left breast mastectomy, lymph node clearance ,fec-t and radiotherapy ) I have been on letrozole since January 2021 and have been getting a lot of pain in my right breast shoulder and arm pit , I have been back to hospital and had a full body scan ultra sound and a mammogram which all came back clear, but the pain does not go away, could this be a side affect from letrozole or something else , any advice please xx

    Hi I am in a similar position.  I finished radiotherapy in Feb 2020 after lump was removed in Nov 19.  I didn’t have chemo just hormone treatment for 5 years.  Three days ago I started to have bad pain below the scar which is almost under my arm at the top of my breast down to my nipple.  It is throbbing and I can’t touch anywhere that’s painful.  I am on Letrozole but have been since Jan 20.  This is the first pain of this sort.  I had a clear mammogram in Oct.  Should I be concerned or is this normal.  Thank you x

  • Hi sorry you are having pain and worries...I had a bilateral mastectomy chemo and radiotherapy... finished in December 2019 and have been on letrozole since.....I too get shoulder and neck pain which comes and goes. I get a burning pain.....I have follow up telephone consultations with my oncologist and asked for a scan as I have started to get very anxious about it as I was "signed" off by the surgeon. It makes you feel a bit stranded and when you get any pain you think the worst. I have a CT scan on the ,18th January....of course worried about going now and catching the virus...I am glad your scans were ok doesn't help with the pain which has to be down to the bloomin Letrozole...keep safe...all the best.

  • I can only assume that it’s the letrozole that’s to blame for the constant pain , my pain is more the right breast not the side of my mastectomy x

  • Hope you CT Scan comes back clear , it’s a constant worry x
