Total number likely to rise before it starts to come down, so why not increase resources within the NHS?
After all, the private sector wouldn't exist without its NHS consultants, NHS referrals, and its ability to send recovering patients back to the NHS? https://www.bbc.co.uk/news/health-66319064

@JoePajak Their big mistake is opening up more diagnostic centres before treatment centres. 🤦
@Lucibee @JoePajak I'm concerned that the community diagnostic centres that are being opened and have nothing to do with the private sector, is sending the wrong message about what the NHS is already doing.
Agreed, the treatment centre lag just moves patients along to another under-resourced queue. On balance public funded community diagnostic centres help underserved communities and addresses some inequalities and help to determine who needs treatment and when, by the nature of diagnosis.
