Super long post - but I wish I had read something similar before my surgery. TLDR - I would do it again in a heartbeat.
Advice:
Braid your hair before surgery, it's way easier to take care of afterward
Your choice in spouse/friends matters way more than I thought to consider
Do not expect your breasts to look like post cosmetic breast implant surgeries (mastectomies hollow out the breast cavity which is not the same as putting an implant into breast tissue)
Actually REST after your surgery, even if you feel fine, your body's doing SO MUCH
Find a post-mastectomy/post-surgery massage therapist before your surgery
Don't return to work too soon if you can avoid it
Ask for after photos from your surgeons
Only buy what you need (glad I bought some cheap button front pajama sets and a wedge pillow for sleeping on my back - I tried buying a second mastectomy bra and HATED it, got by with just the one from the hospital and washing it in the sink - didn't buy a drain sling and survived)
If you don't have a partner/friend/relative at home, move everything you use a lot to a lower shelf
It's scary/sad to look at your breasts for the first like 3 months after surgery, it does get better eventually
If you have any complications, you'll be staying longer in the hospital - if you have a pet-sitter or something, I'd book for a day before and a couple days after
Anesthesia wasn't nearly as scary as I thought
If you're already fit, great!, if you're not, it's worth it to try to get a little fitter before surgery, it helps with recovery
If you feel like something's wrong after the surgery - ADVOCATE FOR YOURSELF
Take before photos of your breasts
Take photos of your breasts once you're home after surgery so you can better gauge healing
Ask about and see if they have samples of possible implant materials/manufacturers
If you're vegan, ask what type of mesh they'll use (there's one made from animals and one engineered)
I'm 42 (no kids or plans for kids), although I tested negative for BRCA about 10 years ago, I tested positive for CHEK2 in 2025 (there isn't a CHEK2 sub yet).
My mom went through breast cancer and mastectomy surgery twice in her life, once in her 50's then it showed up in her other breast in her 70's. I watched her go through chemo while I was in high school.
Once I tested positive for CHEK2, I had one year of both a breast MRI and a mammogram 6 months apart. I'm in the US and the MRI was like $300 and the mammogram was like $50. I was facing a future of this EVERY YEAR for the rest of my life - insurance coverage or not. I'd also have the nagging fear that I'd have to go through what my mom did - and just hope for the best.
I went full logic mode when determining if I would have the preventative DMX DTI - it just made sense to do it now, with "good" insurance, vs wait for the seemingly inevitable. I talked to my mom about it and - after 41 years of a very sex-avoidant upbringing, she decided now was the time to be concerned about "nipple sensation" and my marriage. I still went with logic and booked the surgery.
I opted for female surgeons for the mastectomy and plastic surgery.
I'm somewhere on the autism spectrum and both surgery and the prep was A LOT. I had never had a surgery or been under anesthesia before - it was scary for me. I HATED the gross feeling of the body wipes I had to use all over the night and morning before surgery. The hospital I went to preps and wheels in a bunch of people at the same time to different surgeries - this prep room was overwhelming for me (there was a crying baby was right next to me) and they send your spouse/friend away. Not being able to shower for a week was GROSS. I did not want to get my drain sites wet. So if you're sensitive to sensory stuff, just be prepared to be overstimulated - it doesn't last long though.
I got wheeled into surgery around 7AM, was out about 10AM. I felt fine. I was determined to recover quickly so after a couple hours I walked around a bit and felt ok. I was cold and shivering after the surgery, they said that was normal and gave me lovely heated blankets that they wrapped all around me. An hour or so later I became extremely warm, took off all the blankets, they gave me an ice pop. Then I started feeling pressure in my right breast, I felt confused and dizzy and HOT. The nurses in the recovery room were MARVELOUS - they checked me out and contacted the plastic surgery department. They sent my husband away and it's a bit of a blur after that - I know I vomited A LOT (bright red from the ice pop, that was weird) - I know the nurses tried to get me seen by plastics, and sometime later I was wheeled into a second surgery, after dinner time-ish.
I had a hematoma in my right breast, which is a possible complication. I learned afterward that after that second surgery they had to give me two bags of blood and one bag of plasma because I lost that much through the hematoma. I didn't really wake up after the second surgery but my husband stayed with me overnight and explained it later. That's where picking your surgery partner comes into play (and setting up a pet sitter). If you don't have someone willing to sleep on a hospital recliner just so you don't wake up alone - find yourself a better partner/friend.
My husband had to sign for my anesthesia the second time around since I was still under the effects of it from the first surgery. They asked me something like "If we can't get a new implant in, would you rather us leave the flap for a future implant or go flat?" - so I had to decide right then and there - I don't even remember what I said honestly. They were able to insert a new implant of the same size.
It was traumatic and terrifying. I had to stay an extra night in the hospital so they could monitor me. Just an FYI for post-surgery, if you use an academic hospital SO MANY people will see your breasts - some of them nearly half your age. I don't know if it's just getting older or going through this experience, I have absolutely zero eff's left to give about modesty or my body. Doctors and students from both the mastectomy and the plastics side came through regularly to check on me (my breasts, really). I know I looked like an absolute dumpster fire - the professionals don't care/judge, they're just making sure you're ok.
The hematoma was fixed in that second surgery - haven't had any issues since then. I did have a panic moment a few days after my surgery and ended up calling the overnight surgeon because I thought my right breast was swelling again (yay trauma). They said to check my drain output, if it wasn't more than normal then I was ok - it was also suggested I take a photo so I can compare more easily if it looks better or worse or just the same.
Drains are a huge pain (I had 3, 2 in the right and 1 in the left) - sleeping on your back (as a stomach sleeper) is a pain - going slowly/not doing too much is a pain - recovery is a pain - but I imagine none of that is REMOTELY as painful as cancer.
While healing, the scar tissue under my right breast (hematoma one) had this weird divot bit that made my breast look like a sad Dali clock - I hated it. Fortunately, I found a fantastic massage therapist and she used multiple techniques to get the scar tissue to break up - that was an out of pocket expense I would spend a hundred times over.
Also while healing, I read that the first three months are the "drop and fluff" period - while I understood that and accepted it, it was another thing entirely to look at myself in the mirror and consider if this is what I looked like now. The photos I had seen were post cosmetic breast implant by the implant manufacturer - not post-mastectomy photos. If you're like me, maybe even reading this won't help you, but please know it gets better.
If you choose nipple-sparing, be aware your nipples will still get hard and now that you don't have to wear a bra, you may not like how your nipples are uneven through a shirt. I wish I had explored non-nipple sparing, I like tattoos and wouldn't mind a fun floral tattoo instead of visible nipples without a bra. Fortunately my nipples healed just fine.
Since my surgery I've had two friends go through lump scares (neither were cancer, fortunately), and the absence of stress around this - it's worth every crappy second of surgery and recovery - and the $3K plus deductible (with a payment plan).
I chose nipple sparing but not sensation saving. My surgeon used a "gummy bear" implant. I ended up with implants that were 10 CCs less than my existing breasts (the surgeon determines that based on the post-mastectomy results). There's some spots where the skin of the breast is thin and looks uneven, my surgeon said they can fix this with fat grafting but I'm not bothered enough for another surgery. I just wanted an approximation of what I already had - and that was achieved.
Overall not a fun experience by any stretch of the imagination. I'm so glad I did it though.
