I am 73 and had a double mastectomy a year ago without reconstruction. Like you, I wanted to heal and get on with my life. My gut feeling was that if I could look like myself with prosthesis, I could be fine with that decision and I am. I still had mild lymphedema and a persistent seroma to deal with, but no regrets. My oncologist told me that she had many patients who regretted having reconstruction, but no regrets among those who went flat. A very personal decision, good luck.
