I also had Stage 2, Grade 2 - had left breast mastectomy and sentinel node biopsy (all clear margins and no spread to node). This was only in December 2013, so still pretty recent.
Estrogen positive, progestrogen negative - I am on Tamoxifen - only "treatment" other than the initial surgery.
Didn't have radiation or chemo. Had previously had large dose of radiation to neck region (with a wide field) for invasive thyroid cancer (in 2010) - therefore specialists (3 that I still see for the neck stuff and now for breast stuff) felt it wouldn't be wise for me to have more to the area - the breast cancer was just within the radiation field from previous treatment.
The same doctors discussed chemo and felt that, in my case, the negatives would outweigh the positives and would only make about a 2% difference in my overall 10 year survival - so also didn't have that.
They did say they are going to keep "me under a microscope so I don't present them with any more little surprises" - having regular checks/tests/etc with all of them. I see one of them at least every 2 - 3 months (not including extra stuff they send me for and then phone me with results).
I have been going fine and doing well. I consider myself one of the lucky ones as I haven't had to go through what is seen as the "normal course of treatment" - none of my medical history has been normal - just not me I guess! LOL
I also had a brain tumour in 2002 so the question was raised by my doctors if I should consider genetic testing (having had 3 cancers). A refferal has gone in for this to be done. In the meantime I just figure there is no point in worrying myself about things that may or may not happen. I have survived so far and will keep going on and on and on -
Wishing you all the best - no matter what you decide. Remember you do have choices - make the one that you feel is right for you.
