I had implants 4 years ago in June and they are still cold even when I have a hot flash and the sweat is rolling down between them!

Ah, that's an interesting response. Do I love the new ones over the natural ones? Well, considering that there was cancer in the natural ones, and that I got to choose to have bigger implants than my extremely small natural breasts, maybe. Maybe not….
Really, I would prefer not to ever have had to go through any of this! Cancer knocked me out of commission for weeks. The surgeries were exhausting and painful. I am unquestionably grateful to be alive, grateful that my personal cancer treatment was relatively minimal (bilateral mastectomy without radiation or chemo), but it still was really, really difficult.
Cancer has also made me more aware of the ridiculousness of caring about the beauty or size of my breasts. In many ways, I'd have rather grown old with breasts that started my life with me, breasts that sag and lose their perkiness, than these bigger internal falsies. Yes, I look better in clothes than I did pre-cancer. But my reconstructed breasts have little sensation, are missing natural looking nipples and have scars from armpit to center. They are a daily reminder that I am (and we are all) vulnerable.
I am stronger for having experienced this, more compassionate, more accepting. I've learned a lot about myself and others. But what a price!

Yes, my chest is always colder than the rest of my body.

For some reason, with all the things that are not natural about the reconstruction, this one bothers me the lest. It's noticeable, and it's weird, though, isn't it? Another aspect of how breast cancer changes your life. I think the people who perform all these reconstructive surgeries are wonderful, and i am eternally grateful for my implants. But I'm not sure if anyone who hasn't undergone this experience really understands the extent to which we - our bodies - will never be the same.

Do they feel a lot different in temperature from the tissue expanders with saline in them?
