It depends on what type of cancer it is. My sister wasn't even in Stage 1, but she had small squamous cell cancer, and it is the most aggressive. It responds well to treatment (radiation and chemo), but it always comes back. She was dead in 18 months.
Yep, we have a family member being treated for cancer of the uterus.....she’s now going through another round of chemo only a few months after her last round... .....some cancers are real difficult to contain and or treat regardless of what stage they’re in.
I am sorry to hear about your sister. My own sister had stage 2 cancer. She is a survivor for 3 years now.
