Re: Enlarged tonsil? Could it be cancer?
My daughter also had really large tonsils, she was born with them like that. I found out about them when she was 6 and I rushed her to the ER because she was weezing and had a very bad cold. I was told that her tonsils were twice as large as they should have been and they were the reason she couldn't breath properly. Her large tonsils actually caused a lot of problems for her, she would get a bad cold every 6 months since birth and constantly have ear infections. I had to use a nebulizer on her a couple times because she couldn't get enough oxygen. After her tonsils were removed everything for her changed, she's now 11 and maybe gets a cold once a year if even that, she hasn't had one ear infection since the removal and her breating is perfect.
It was so sad that it took 6 years for me to find out that something as simple and weird as large tonsils could effect so much of my daughters health.
I'm not sure if my daughter's tonsil situation is the same as yours because I was never told anything about cancer but that could also be because her low oxygen levels were the major concern. I do hope this helps you in some way I know how scary it is when you're afraid that something serious could be wrong with your child.
