I understand where you are coming from, my biological mother also had breast cancer 3 times, the second ended in a double mastectomy and couldn't do a reconstruction, the 3 bout the cancer ended up metastasizing in her blood and surrounding tissues, even with treatment she only lived a short time after the 3rd diagnosis, we lost my grandmother(her mom) 6 months later to cancer of the lymph nodes. I didn't take care of them directly (grandma took care of mom and a family friend took care of grandma, not my choice but i had no say and she declined quickly) like i did my paternal grandfather, but i handled all of their last wishes. I would not wish that on anyone and for those who have had to have my respect.My late mother lost a boob to breast cancer*, and wore an in-bra pad similar to Renka; tissue damage from both surgery and chemotherapy/radiation prevented reconstructive surgery. Even in her early 60's, it was a big hit to her self-esteem.
*She passed away several years later from the same cancer metastasizing; it was treatable, but wasn't curable. I was her primary caretaker for most of her fight.
