Hi, welcome to HCM I am Dr Das
First of all, you just gave the FNAC report. From this stage of the breast carcinoma cannot be decided.
For staging, we need the size ofthe tumor
(more than or less than or5cm) , the lymph
node status, if lymph node present then situation, level, number are also needed. And if there is any metastasis present or not , is also important.
Regarding treatment, stage is to be determined first.
