Thanks for the good wishes everyone. So, I had the ultrasound Thursday morning. The good news is that the Radiologist told me that although there is a slight change around my surgical scan since my last ultrasound it wasn't necessary for me have a biopsy as there was no inflammation of the tissue underneath the rash and no obvious mass. Then my GP rang me in the afternoon after she received the radiologist's report. She said nothing obvious showed on the ultrasound report so not to panic, which was really good, but went on to say that she wasn't entirely happy and that sometimes it's hard to diagnose more serious things and you can get a false positive. She then said she would speak to my oncologist to see about getting a skin biopsy taken if the antibiotics haven't knocked it off by next Friday and that I had to come back and see her next week. So I think overall it is good news, but there is still a degree of uncertainty there and I really appreciate that my GP (who has had breast cancer herself) wants to be very thorough and not dismiss anything just in case. Unfortunately for me I reacted really badly and I just couldn't block it out of my mind while we had our mini canoeing holiday. It just played over and over again in my head like a broken record. I kept checking my rash every couple of hours to see if it has grown more. My boys were in the car when the doctor rang and so heard everything whereas before I didn't tell them I was getting checked out. So it was a very sombre mood for the trip. Now I feel like I am waiting for the other shoe to drop until I see the radiation oncologist on Friday. I really wished I could have had a biopsy so that it would definitively so "nothing to see here, so move along". Not the mindset I wanted to be in just before I return to work after 4 months off.
