Dear Setm, Post surgical or
radiationCystitis - noninfectious
Radiation therapy therapy pain in the breast can occur. Not always is there an exact explanation for it, it can be the healing process or the changes from the surgery +/or radiation therapy. Assessment would be made to see if there is an identifiable cause such as scar tissue formation, infection, a lump at the surgical site causing pressure. This may diminish as more time goes by, and the further you are from the treatment. In the meantime you might try some simple comfort measures to see if it helps for instance, a bra that provides good support.
