New Mass--I have Questions

[cafe1084]

Hey all,

I found a new mass under my left axilla this past week. It is a good 2 1/2 inches from my mastectomy scar and feels the same as my breast mass was and is approximately 1 cm x 1 cm. I saw the oncologist and the surgeon today and was scheduled for a CT scan and a biopsy on Monday. The surgeon says it is possible that it is fat necrosis. I have heard of this briefly with reconstruction, but I was wondering if any of you have experienced it and thought it was a recurrence. I am also interested in knowing if any of you have developed a resistance to herceptin. If this is a recurrence for me, does it mean that the herceptin I've been getting for all of 5 months isn't going to help me ever again in the future? Breast cancer is bad enough. fearing that I'm resistant to Herceptin is worse!

Thanks,
Steph C
