Head neck Cancer

Hi I was diagnosed with squarmous cell carcinoma 2019 and apart from trauma from surgery I m doing ok , but did get diagnosed with lupus exactly a year later , I have a relatively good size sore on roof of mouth same side as original cancer , but it was in tougue last time Gp dissmed it over phone appointment , I also rang mcmillian nurse and was told not every sore will  not be cancer which I do understand , but I'm petrified.  Dentist had taken pics of it but can't refer till next Thursday as they have to see if it's still there and I do understand that to , but I feel that just reassurance would help , the dentist is worried but told me that it's policy ,it's really upsetting as  consultants GPS consultants say got no where we are if worried , but pointless as I've tried xx
