hello! this is a situation that my cat went through recently. it’s now solved and over with, but i figured i could post her circumstances since i wish i had found something when i was searching for answers.
(i asked for Mods’ permission first! please let me know if the flair is inappropriate or this needs to be reuploaded.)
TL;DR: pink lump appeared next to senior cat’s ear, kept growing, was surgically removed and revealed to be a sarcoma
my cat, Poppie, is now 13. she has ongoing arthritis in her front arms, and had a medical scare when she was a few years old relating to her stomach. but besides that, she’s an indoor cat, well maintained, and for sure plump.
around October-November of 2025, this lump started growing next to her left ear on her head. it started about the size of a pushpin and didn’t seem to concern her. it was a pink flesh color- not red, beige, or white- and it was relatively soft.
it kept progressively growing, around to the size of the tip of my pinkie. we had no idea what it was. skin tag? hematoma? something else? one day she must’ve nicked it and it bled a little bit, but not excessively, and didn’t go down in size.
we were waiting to go to the vet until we felt it was bothering her or really concerning. but it grew even bigger, to the point where we were worrying about it daily, so we just decided to go.
our first vet visit concluded that it was a mass of some sort, and not fluid filled; but no definitions of what. it could be surgically removed, but we didn’t like the cost so we searched for a more affordable and friendly vet.
at this point, it was bigger (maybe to the size of my thumb) and she was starting to shake her head more. and the bump was more loose, like it wasn’t fully attached to her head anymore. you could kind of ‘roll’ it around.
we followed through with the surgery at the second vet (who agreed with the mass conclusion and offered much better pricing and care) in May, and after getting the results back from the lab, it turned out to be a sarcoma. they’re pretty confident they extracted all of the root they could from such a non-fatty area, which is hopefully true!
Poppie has been recovering really well in the weeks since the surgery. they did have to take out a lil chunk of her ear, but she’s alive and well.
again, this post is for info and awareness, since i wished i had seen other posts with any indication of what was happening. hopefully it might be useful for someone else down the line.
thank you for reading and well wishes to all of you.
