If you are considered at higher risk for ovarian cancer you can have the CA125 blood test. I did for years as my mother and one of her sisters died of this cancer. But I don't think it's a generalised screening test.
It is a very sad tale about Sean Duncan. Yet - Sean did not do all he could to help himself. His cancer was diagnosed in the US where he wasn't a legal immigrant it seems. So no health insurance etc. Eventually he was operated on, marriage failed and he returned to the UK. But here he didn't go for the checks he should have done. It's hard to read that the NHS and non-believers in gender identity ideology should take any blame for this (apart from the NHS going along with gender ID in the first place). We all, no matter who we are, need to take responsibility for our health. There are no magic medical wands.
I believe gender dysphoria is an MH issue, it can be nothing else. So we have people like Sean who find parts of their body very difficult to deal with because we have sexed bodies, however much some dislike that fact. This makes them reluctant to seek out the proper health care. We are in no way to blame for this. All of us here, I'm sure, do not ill-wish any trans people, want them to live long and fulfilling lives. However, to do this, they need to remain on the right side of reality and this they often are unable to do. Inevitable this will lead to problems.
This saga brings muddying of the language into sharp relief. It's what happens when we no longer have words to describe ourselves accurately. Who is going to be helped by reading that ovarian cancer predominantly affects females? Some men will maybe start to wonder why they aren't being invited for screening. If gender ideologists had even left the word 'female' alone, then at least we could all know who it applied to but no, they had to have that word too. As well as woman.
We need medical records to show sex, which means birth sex, very clearly and also 'gender identity' if required. I'm sure I read here recently about the timescale of different specialties in the NHS switching from 'sex' to 'gender' at the behest of the gender ideologues. It's been going on for some years, clearly, but some of the switching was as late as this year (sorry, I know this bit isn't very clear). But if anyone bears any responsibility for making this mess worse than it is, it's those people.
