My 73 year old Mother recently had a tumor removed from one of the milk ducts in her right breast. She had started bleeding from the nipple out of the blue one day. It was Stage 0 - ductal carcinoma in-situ and the doctor is recommending radiation therapy... 6 weeks, 5 days a week. She was leaning toward the mastectomy to be done with it but he says for her age it's a very rough surgery to go through. She has now been told by a friend that her sister had radiation therapy for breast cancer and came down with rheumatoid arthritis as a result. I've tried to research this on line but find nothing on it. Can you please tell me if this is a possibility/side effect of treatment?
My Mom is in excellent health... other than giving birth to her 2 children in 1957 and 1958, the only other time she was hospitalized was in 1964 for a bockland (sp?) cyst in her birth canal and she had outpatient surgery for a cataract in 2003! Other than the occasional cold or sinus problem, the only other thing that she's had was the shingles at 65. Her sister died 12 years ago of cancer from an unknown source that metastasized in her liver. The majority of her first cousins on her Mom's side have all had and died from some type of cancer so my Mom is concerned as you can imagine... as am I.
Thank you.
