My mother (71 years) is detected with Grade 2 ERPR + ; Her2 nue - ki-67 : upto 50 % breast carcinoma. CT scan revealed left breast lesion with 1 auxilary lymph node 3.1 x 1.3 cm with preserved fatty helim. No other metastasis was observed.
We underwent a radical mastectomy + auxullary lymph node sampling. Out of 12 nodes , 1 was +ve. (pT2pN1).
She suffers from Hypertension(ESPIN AT 0-0-1), Diabetes(Glycomet GP2 1-0-1) and also thyroid (Thyronorm 1-0-0).
(High values of thyriod and diabetes resulted in postponing the surgery by a week untill brought down by higher dosage).
As 1 node is +ve, oncologist suggests Chemo.
She is already on nonadjuvent tamoxifen ; with good response. Doctor suggests to shift to Letreozole, which should be OK.
However, we are unable to decide if the benefits of chemo will outweigh the side effects, given her age and history.
Request your expert advice on this. Thanks in advance.
