Some patients seem to be worried that they have still not received a letter from the NHS via their GP, informing them that CML is included in the high risk category along with other cancers, Leukaemia as well as other conditions.
If you read the links to the NHS and Gov.UK provided in the post pinned to the top of this page, it is stated that you may not get the letter until 29/02/20. The notification will be from the NHS via your GP Surgery.
After 29th March, if you are still worried that you have not received this notification from the NHS, you should then contact your GP surgery and not your hospital.
I have not yet received this notification either, but I am fully aware of the advice to isolate for 12 weeks.
