I’ve been having trouble swallowing the last couple of months?

I’ve been having trouble swallowing the last couple of months. It feels like my food is sticking in my throat and I’m going to choke and then I’m gasping for air. It’s getting worst. Even liquid is difficult now. It feels like there’s a lump on the right side of my throat making it hard to swallow. I’m terrified it could be cancer like my father

Yes
General Information: I’m diabetic. I’m waiting to see a ear nose throat specialist but it’s not for another four weeks. I’ve asked for an earlier appointment but they say the clinic is full up. I’m frightened it could be cancer (like my father) and it’ll be too late by then
