Hi and thanks for the post,

It would be very rare for someone of your daughter's age to have cancer of the tonsil.

Having had cancer yourself, it must be hard seeing some ongoing symptoms that are lasting for more than a few weeks, but explanations other than cancer are far more likely. It's not unusual for teenagers to have frequent throat infections, or swollen tonsils , but you can always discuss your concerns with the GP if you or your daughter remain worried.

It's easy to say try and not worry, but hopefully things will start to settle down soon.

All the best

Wanda
