Im 48 and was diagnosed with grade 3 invasive ductal Her2+ breast cancer in August, also in 5 Lymph nodes. The tumor was 6cm but after 3 rounds of chemo it has shrunk to 1.4cm, I have 1 more chemo to go and then I will be having a Lumpectomy. This site has been really informative and helpful. For everyone going through this keep going and try and stay as positive as you can as some days will be harder then others. Sending my Love to all of you on this **** journey
