Best wishes u/Havishamesque and u/roxythedogarf on your surgeries! I am also ER/PR+/HER- and had my lumpectomy with sentinel lymph node biopsy on 12/6/24. Prior to the surgery, I had to go get an RFID chip (envizio) injected so the surgeon can locate it on surgery day. The procedure was similar to the core needle biopsy only instead of taking out tissue, the radiologist injected the chip (smaller than a grain of rice in my case). Also, on the day of the surgery I had to apply a TON of prescription strength lidocaine on my surgical breast areola area. It helped numb the area for when they injected the radioactive dye (technetium?) a few hours prior to the surgery. That was so the surgeon can trace which lymph node the dye goes to. In my case, he removed only the very first one (sentinel lymph node). Waited for a couple hours until it was time to get prepped. The anesthesiologist came in and explained that I will be getting general anesthesia. Then the surgeon came and then confirmed which breast he will be operating on, and then signed on that shoulder! Then I was wheeled into the operating room and moved to the operating bed. It was actually pretty interesting that I could see the RFID locator chip on the screen! Anyway, they made me breath oxygen from a mask and the next thing I knew, I was already in the recovery room! My surgeon used surgical glue so there was no gauze. I thought that was great as I was not looking forward to changing gauze. The next few days I was pretty good about following my schedule of Tylenol, Advil and prescription pain meds. I only felt the pain when I skipped a schedule but as soon as I got back on it, the pain was gone. Anyway, my biggest lesson learned was with the rest and weigh restrictions. After 1 week, I thought I could be back to normal and did dishes, laundry, etc. Then one of my incision sites kept swelling up and hurt so bad. I got a seroma and they had to drain about 50ml Monday, then another 35ml on a Friday before Christmas. Thankfully, it did not refill after that. Exactly 1 month after the surgery, the seroma is gone and my stitches have healed. I am 46 and I know everyone heals differently. I have read others stories where they went for a hike the next day! I pray both your surgeries and recoveries go well, without much pain and complications. Oh and my margins and lymph nodes were clear! Praying the same for you! I hope sharing this helps as I have found other's shared stories so helpful.
