Hi Natalie, What a time you have had! I hope your armpit feels better now. Did the physio at the hospital give you exercises to do? It really makes a difference down the track to do them as often as possible.I am also TNBC, and we are all usually Grade 3 (aggressive) when diagnosed. My tumour was 3.5cm with no lymph involvement, and I had a bilateral mastectomy. My Medical Oncologist gave me chemo for 3 months and followed it with 28 radiation treatments. Have you seen your MO yet? With treatment the statistics can be a lot better than one in two.It is now 3 years since I was diagnosed, and I only need to see my MO annually. I hope your sinus surgery goes well.Stay in touch - we are all here for you when you need us - xxx Michelle
