Hi @Chance
I had a double mastectomy (skin sparing), direct to implants in May this year. Surgery was around 4 hours and I spent 5 days in hospital - two drains removed before discharge.
I did not have enough tissue for DIEP flap, but am very happy with my implants - at 47 years old I wanted something there. I got small ones (like my original breasts) so no expander required. I also have feeling in both breasts (although reduced), which was a pleasant surprise.
I had invasive cancer, so you could ask if nipple sparing would be appropriate for DCIS.
Best bit - symmetry, peace of mind (although there is no medical benefit on overall survival), no radiation and no more mammograms . Worst bit - managing two drains in hospital and longer recovery/rehab.
Feel free to hit me up with any questions.
