What could be the reasons for having a large lump in your throat?

Cancer is possible. If the mass is visible it needs to have biopsies done. Some people have a sensation of a lump in the throat. This is called globus sensation. Most common cause of this sensation is felt to be secondary to acid reflux. With or without heartburn. Look up lprd for more info. But if you have a visible mass it should be evaluated.

I'm sure there is.... a reason for your symptoms, but unfortunately, a 20-word post to doctors who know nothing about you will not get you a reason over the Internet. There is a disclaimer that applies to HealthTap activities, which is that the doctors on it don't diagnose or treat anybody. It sounds like something that an ORL or GI doc would see. Although with NHS I imagine you have to start with a GP.
