Hello,MK, and thank you so much. I just called my sister and in fact she has now made an appointment with the oncologist for this Tuesday, so I am much relieved. It may be a problem with scar tissue; she says it's very tender and "crampy" and there's a ridge where she had the lumpectomy. My friend who is an OB-GYN said an infection is quite common following radiation. Anyway, I will update you next week once we know more. Cheers,
Amanda
