Crested Duck with a lump on her cheek

[azhnasa]

Hello Friends,
I have a Crested Duck that started developing a mass on her cheek, next to her beak.
When I touch it, it's not soft and also isn't painful for her.
Looks like a fatty mass but it can be infection.
Her eye is a bit watery but that's about it.
No discharge or discomfort.
She is completely living her normal life.
It started growing few weeks ago but it has stopped and hasn't gotten worse.
Do you guys know what this is, what may have caused it and how to treat it?
Attached are a few photos.
Thanks.

Hello,

Thanks for the links you sent me.

After reading them all, I don't think what my duck has is Follicular Cyst or Feather Cyst.

Please see the 3 photos I had attached and compare them with the photos for Follicular Cyst or Feather Cyst.

It more looks like a tumor to me.

It is not painful for her when I touch it so it is probably not abscess.

What else it can be ?

If it is just a tumor, how would I know whether it is benign or not ?
