2 tumors in 1 breast. Need 2 oncotypes?

I had two invasive tumors.  They were in different quadrents of the same breast and had different er/pr/her stats.  One (1.2 cm) was 98% estrogen postive,  the other (0.8 cm) was 48% estrogen postivive.  Although the standard of care with multricentric cancer is to base treatment on the largest tumor, that didn't make sense to me.  I had oncotype tests done on both tumors.  The score for the larger tumor was 8, for the smaller one 16.  

Before I got the oncotype test for the larger tumor, my onc recomended chemo.  He didn't after he saw the score.  But what I did, to make sure I was comfortable with the no chemo decision, was to run calculations on the possiblity of having a recurrence from either tumor, based on the ocotype scores.  To me that made sense as the two tumors had different biologies.  The results I got from that indicated to me that chemo still wasn't worth the risk.  I would have gotten a 2% to 5% advantage, depending on the assumptions I made.  So the risk was about equal to the chance of permanent side effects from chemo.  

I think it is good your onc wants to considering both tumors.  That makes sense to me.

Had second mastectomy, last Friday. First on 1-2005. IlC, 2 masses approx. 2cm with scattered areas throughout the breast. Had chemo, rads. Low and behold, had MRI 3 1/2 weeks ago, and 2 5mm areas showed up on the right side. Had biopsy, POSITIVE for ILC.  Had sentinel node biopsy-all negative, and remainder of breast tissue-negative.  Going to see surgeon and oncol. on Wed. Hoping and praying NO CHEMO!  Been there and done that.  Does it go alot on t he Onco type(which I don't know that yet). Thanks so much!
