This is a bit personal, hence NC and deliberate vagueness, but basically two family members have been diagnosed with cancer. One of them has something very rare which was only picked up because their spouse used to work in the field and has been bugging the GP for getting on for two years about niggly symptoms that looked trivial but turned out to be anything but. A big operation is required now and the outlook isn't brilliant but they're at the age where 5 years is a real bonus.
The other family member has just been told that theirs is very advanced and likely to be terminal. This person is very definitely much too young to die. And the awful thing is that they have been taking medication for years on repeat prescription to mask symptoms that were probably a sign of the illness. No recall from the GP surgery, nothing, until other more alarming symptoms happened.
Now I know that everyone keeps saying please see the GP. But what if you get fobbed off on a regular basis? Or getting an appointment requires something approaching top-level security clearance and a four-week wait? And then when you get there, well, it may be you have something rare enough that a GP used to a regular stream of coughs and colds and jabs and diabetes checks will never have seen it and won't have a clue. Cancer is such a complicated set of diseases, how the hell can a non-specialist (albeit qualified) be able to spot the early signs when they are so vague and non-specific? (I'd be interested to know how other countries manage this as well).
