Best treatment for invasive and in-situ carcinoma with lobular features, sbr grade 2, 8mm in size?

If this was a....: ...Exam question, i'd say: lumpectomy with sentinel node analysis followed by radiation or mastectomy with sentinel node. Either would be followed by 5-10 years of oral endocrine therapy (tamoxifen or ai) if the tumor is er or pr positive. There may be other factors i'm not aware of that may move a doc to take a different approach so have a good talk with your doc about your options.
