FTM, my daughter was 6 weeks early and is currently 19 days old, we found out she has sacrococcygeal teratoma (SCT). it's a small tumor on her lower back. she will have to have surgery to remove it in a month or 2, I am so nervous about them giving her anesthesia so young. has anyone else had to deal with this? I could use some advise.
