Re: Why are there final appointments?
As I understand it, the main reason is that there's no point in treating early slow-growing breast cancer above a certain age.
Many of the treatments would kill you, while a slow growing cancer wouldn't actually affect you in any way before you die of something age-related.
More aggressive cancers are an entirely different thing, however those aren't generally found this way - or at least, not early enough to help.
Check your breasts and your balls. Seriously, do that often.
