Grade 3 tumor

I was diagnosed with Stage 2 Breast cancer , Tumor size 2.9 ~ Grade 3, ER positive , positive  nodes, Her2 negetive.
My question is ~ Will chemo be benificial to me . They recommened it because my tumor is a grade 3 and I had node involvment . But my cancer is ER positive and I thought that Chemo is not effective on ER positive Breast cancer but Tamoxafin  is the best choice ??? Would my tumor be er positive ??

ER + tumors and Chemo have nothing to do with one another. Chemo is a "given" with large tumor and node involvement no matter what the hormonal response,  (+ or -) The ER response simply means that the tumor was dependant upon the hormone for growth. After your other treatment you will no doubt be put on hormonal therapy (Tamoxifen) to block the production of Estrogen which will reduce the chance of recurrance. Chemo is necessary to kill any cancer cells remaining in the body after surgery.    Regards .....

Thank you for your comment . But my question is~ Is  Chemo effective on ER cancer ?? I was told that it was not ???? I know Tamoxifin (tamoxifen) is. I heard that chemo is very effective on Her2 type cancer.
I know Chemo is very toxic and damaging to the body . IS it worth the doing if it isn't effective on ER cancer???

I am having difficulty believing you were told that chemo doesn't treat cancer. Hello.....

The pathology of your cancer might be estrogen positive and her2 neu negative but that doesn't have anything to do with killing cancer cells with chemo. I'd strongly suggest you do alot of research since I don't believe you understand the difference thanks to bad info. Sounds like the doctors are right on.

You have an aggressive form of cancer as evidenced by it spreading to the nodes. Chemo and radiation are for sure a good choice. Best wishes.
