I'm not really understanding why you want to take a conservative "wait and see" approach..... but i'm often slow on the uptake !

I'm with most of the other that have posted, get a biopsy done as soon as possible.....it doesn't hurt that much

As some people on here already know, I've been through surgery and 18 weeks of chemotherapy for breast cancer, i'm about to start 4 weeks of radoitherapy........... believe me better to deal with the issue now than in 6 months when it could mean going through the same.......... I really wouldn't want you to have to do that........
