I had a screening a few years ago due to some pain or a lump (can't honestly remember as it was amongst a long gynae illness). I was called for my 50yr screening,  and they were surprised that I had already had one screening as there were no records. Both screenings were done under the umbrella of the same hospital.

I've now been recalled for further tests on Monday (it's Thursday,  letter posted yesterday,  screening 22.2.22 ) after my recent screening and I'm worried that something could have been missed on that original screening, and that they don't have that data to refer to.

I've had no symptoms that I'm aware of, though now I feel like there's minor burning pain in the outer side of my right breast near my nipple. Probably psychosomatic . 

I couldn't even get through to confirm my appointment! I'm panicking about that too as I only have Friday left to respond. 

Who should I contact, who should have details and where do I legally stand if they've missed anything because of the missing documents (not the 1st time my notes have not been maintained, but under a different hospital)?
