Hi @Kelly88 sorry to hear you've been diagnosed.
I'm 31 and almost 3 weeks post double mastectomy with recon. I was also freaking out about the surgery and more so the recovery. But honestly it's not as bad as it seems. The first week you are at your worst but you're in hospital for a few days or even a week like I was. When I went home I really did bounce back quickly. I think the age also helps you to recover faster. You're going to be in good hands with your surgeon and the anaesthetic is safe and that part is the least worrying part. WIshing you all the best for the rest of your chemo xx
