@chrissy1, I'm so sorry about your huge challenges! I have breast cancer that spread to my liver and brain. I never smelled anything unusual. It can be a constant worry about a new cancer location, but I try to not worry about what I don't know (such as until biopsy results confirm cancer - no worries about cancer until confirmation), but most cancer patients do worry. Connecting here is a great step. Also check in your community for cancer support groups, or the Livestrong program (you can Google it) - it's a 12 week exercise program for cancer patients. Illness, especially cancer, can be overwhelming. I was reading about talking with people with other situations, including, "at least it's not cancer." Nobody's told me that, because it IS cancer. We can get through this! Keep asking questions and listening to your body. Please let us know how you're doing. Blessings!
