Hello, I have a 10 y/o cat names Inky who was adopted at about 6 months and has been indoors since, neutered. He has a chest mass that I noticed about a month or so ago, medium sized, has stayed about the same. It's not particularly hard but not exactly soft either. I thought it was lipoma so we took him to the vet this evening. he was shaved, here is a photo of the mass, kind of has a head...the vet said whatever it is, it is not good. He does not react when I touch it so im assuming it is not painful. He has no other areas of lumps. His appetite is great. No changes in the litter box habits.

as a kitten, he was sick with some kind of disease when I first took him in. our first night together was great, next day he was paralyzed from waste down. he saw a vet at the human society who told us to euthanize him. she said whatever he has, it's no good, let him go. We bought him home, he still wanted to eat so we gave food, pedialyte. over the next 48 hours, he had many, very frequent, what appeared to be, seizures or muscle spasms. he eventually made an interesting poop containing white, stringy, mozzarella cheese looking poop. we went to bed, and next morning inky woke us up, running around the room. it was truly a miracle. this cat was paralyzed from waste down, now running around like nothing ever happened. the vet from humane society called to inform us that his labs were perfectly normal. no one knows what happened to him but since then, he has had neurological deficit - not major, but if you throw something or try to play with him, he can't follow with his gaze, doesn't run after toys you throw at him to chase, can't make high jumps. the reason I am telling this story is to see if there is a connection between this mass and childhood history.

He is scheduled for x-rays, ultrasound and labs tomorrow morning. Does anyone have any experience with this? I am scared. Cancer diagnosis has been haunting me since 2021. Any input is appreciated.

Hi. I am so glad you didn’t listen to the humane society vet. He was never vaccinated there, was he?
You really won’t know until they do more testing as to what this is. If everything looks okay, I would suggest having it removed. You may want a specialist to do the surgery.
I don’t see many lipomas in cats. It can happen, but just don’t see it often.
Please keep us updated with what happens.
is it moveable or does it feel fixed to the body?

It’s kind of mobile, and that was part of the reason I didn’t worry, initially, and thought it might be lipoma. I’ve been trying to get him in to the vet over the past 6 weeks, also dealing with a family emergency and other sicker cats so this got overlooked. I didn’t know that lipomas are uncommon in cats. He is otherwise feeling great!

I don’t remember inky getting any vaccines at the humane society but it was about 10 years ago, I can’t really recall. Wete you thinking injection related fibrosarcoma?

Try not to worry untilm you know for sure. Cats often get benign cysts as they get older, my 10 year old has one one teh inside of his thigh. Hashad it for years, about the size of a large grape. Mobile is good, usually cancers are hard and immovable. Keep your chin up, you are doing all you can!

Well, you guys are so darn kind! I come here for support and have never been disappointed! ❤❤❤

we just picked up Inky from the vet. The mass was completely removed, the vet does think it’s cancer. Tissue was sent for pathology. No other lesions or masses were spotted. He had an US and an X-ray.

he looks good. He wants to eat but we have to hold off for 2 more hours. Fingers crossed that this was one and done! I will keep you guys posted as I hear more.

Oh no, I’m so sorry…..I’ll keep her in my prayers too, like you said you and your family need all the prayers they can get. There are still miracles out there, may God bless you all…….
Thank you for your kindness. I really appreciate it from the bottom of my heart. I am doing my best to still believe in a miracle.

an update for you guys regarding Inky's chest mass...the pathology came back, it is a low grade soft tissue sarcoma. Due to the nature and how it grows, they were not able to get all margins of the tumor and I was told to keep a close eye on it for re-growth. There are no signs of metastasis at this time. He is doing well clinically, zero changes in his daily activities, still a food monster so we are grateful. Thank you for your kind regards and support, :heartshape:

I'm very, very sorry to hear this, though it's great to hear that Inky is doing well in so many ways. I hope that continues. ❤

Hi. I am sorry for the diagnosis. How is your sister?
I read that cats with low grade STS have a fair prognosis, he is only 9 years old and otherwise good health is on his side. The vet didn’t seem too concerned, he said to continue monitoring and if it comes back, we remove again. Currently no signs of spread. There was a study done to assess prognosis based on grade of sarcoma (low to high grade), but study group was small with 47 cats. I guess time will tell, hoping for the best.

My sister is not well, she’s declining quite fast and the medications don’t seem to be helping in preventing tumor growth. We started a new medication last week to slow growth and alleviate her confusion. So far we’re seeing minor improvements. Hoping for a miracle. This has to be the darkest phase of my life, I never knew pain so deep. We had so many plans to do things together 😭😭😭

Thank you! Yes, he’s doing well. He’s clueless about his diagnosis so that’s good! Eating, playing, doing all the normal cat things. He’s a trooper, he’s been through quite a bit, he knows he’s well loved!

This is great to hear. As is your vet's reaction. I really hope Inky will continue to do well!

I'm very sorry to read about your sister's condition, though, and share your hopes.
