I think it depends on your overall health more so than age. Also, which type of reconstruction you are considering. I am 61 and back in treatment for a recurrence. In the meantime, I developed a capillary contracture around my implant “due to radiation” per MD statement. To repair this as soon as I finish treatment again, I asked the same question regarding age. His response was that you had to be able to walk 1 mile and up 2 flights of steps before being considered for DIEP flap reconstruction. Implant reconstruction, walk 1/2 mile and go up 1 flight of steps. I would point blank ask your plastic surgeon what the criteria is for each type of reconstruction you may be considering.
