I had a mastectomy in February and all my lymph nodes were clear as was my CT scan. My oncologist said to me that chemo was up to me as well - she said she would recommend it due to my age, 43, and to prevent recurrence. I decided to go ahead - I didn’t want a “wish I had done chemo” 10 years down the track I’d it came back. What kind of chemo are u having? It’s a completely individual decision though. It wasn’t the most fun experience of my life but it’s done now and if the cancer comes back at least I feel ok I did everything I could. I can’t comment on the port as they were able to insert a canula with me. Good luck and big hugs xoxo
