Thankyou for your swift and helpful replies, it really helps.
My job starts in 9 days, and being a performer, is potentially very physical, and also we have to certify fitness before starting a job.
If I enter the system, I am on a list, and can't guarantee that the procedure will be booked in before I'm on tour(January)
Am on the Urgent Referral list, so that might make a difference.
If a biopsy shows something, of course I will need to get treatment, rather than being on stage on tour.
But your replies are giving me a perspective, and thanks....
