Going Private for a Diagnosis

Hi

i have chosen to see a private dermatologist regarding a suspiosious skin lession. The dermatologist was concerned and chose to remove it. Still waiting on results. I chose to do this as the local NHS for skin cancer care is overloaded and I was told I would have to wait over a month to see anyone this was after I chased my referal after not hearing anything. 

once I have the result and iif it turns out to be cancer I don’t have the funds to have full treatment in a private hospital. And would have to go back to the NHS. Can anyone advise how I go about this, or have been through this and can provide me some guidance 

any advice would be great

thanks
