I have it through work for the family, initially through BUPA and now AXA. Wife had breast cancer last year and treated at the parkside in Wimbledon. Her initial diagnosis was via the NHS and that was super stressful. After surgery to remove the lump, the oncologist said no need for chemo as small lump with no lymph node involvement. BUPA however insisted she has the oncotype DX test, in the US to look further into the biological makeup of the lump. The test is not available on the NHS. Results came back as high risk of recurrence and she needed chemo.
The lesson here is that NHS is reactive, it fixes people at minimum cost and does not focus on prevention / cure. The private sector cannot afford to do that, as reccurrnces cost far more in the long term.
We will always have private, as long as it’s available to us.
