Hi Terri
my mum was diagnosed with breast cancer in her late 70's too. She wasn't in otherwise good health so surgery was not an option and she was treated by meds alone. The large lump reduced in a few weeks to a much smaller one, only barely felt by the consultant :) She remained on meds for life but the cancer caused her no problems and she did not need any radio or chemotherapy.
It may help you to know that we were advised that on the plus side at this age level hormones are low and everything slows down dramatically so unlike this type of tumour being found in a much younger woman being a cause for alarm, it was not a high risk at all in such an elderly patient.
Please get yourself checked out thoroughly of course - my mum didn't know if her family line was prone to breast cancer as she lost her own mother to meningitis when only in her early 30's and her grandmother to something unusual (then) in her 50's - definitely not breast cancer.
On the prayer list kiddo and meantime try not to be too worried.

ETA: my mum's death was nothing to do with her cancer - in case that wasn't clear from my post
