I'm temporarily down in Miami.
Chemo has a lot of rough side effects. About half of cancer survivors have a chronic medical condition that's related to chemo or radiation therapy.Cancer is awful because it has a will to survive, and replicate even after seemingly full removal. She’s going to survive. Hopefully she chooses chemotherapy as well if her oncologist recommends it, my aunt is going through chemo currently because the cancer returned and she didn’t do it the first time, and cancer gets much worse a second time evolution and shit.
There have been a ton of advancements in breast cancer treatment over the past 20 years. If something more targeted like CAR-T cell therapy is an option, Dawn should go for it. She should also strongly consider participating in a clinical trial for an immunotherapy - these kinds of treatments show a ton of promise, and they don't have side effects that are anywhere near as rough as chemo.
Dawn appears to be getting treated at an NCI-designated cancer center, so she hopefully has some decent options.
