While there is normally irregular bumps around that area of the lip, it is usually not that big. I would have your vet check it to be sure. It maybe a growth or an infection or inflamed from that tooth rubbing it

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. A lump in this area could be due to local gum / skin infection but it also could be a tumor (benign or malignant).
A visit at your local vets is recommended to examine Gabby in full and decide on the treatment plan. Your vet may want to prescribe a course of antibiotics or anti-inflamatory agent first, to treat the inflammatory / infectious process. If this treatments does not help, a needle aspiration or surgical removal of the growth may be necessary.

Thanks for using Petco Pet Education Center, formerly Petcoach! That is a great picture and I can see what you are referring to clearly. I am concerned that this could be a growth for example. Another possibility is that her canine tooth is rubbing on the gum tissue and causing inflammation and an examination would help determine if that seems likely. I highly recommend that you have Saffy evaluated by a veterinarian to have this sampled. This can be done via a fine needle aspirate or a biopsy to determine what this is exactly. Then therapy can be directed at that specifically. Hoping that this is benign. Good luck and have a great day!

My senior cat's mouth is drooping. Are these lumps serious and need removal?

This might need to be removed surgically, the best way to find out is to take her to the vet, they will aspirate a small sample with a syringe and needle from the lump, then they will send it to the lab to find out if the tumor is cancerous or benign. if it is cancerous it will need to be removed for sure, but even if it is benign, due to the symptom it causes, your vet might advise surgical removal.

My cat has a swollen lip for a week. Is it serious? What to do?

Any lumps/bumps that you notice on your pet should be checked out by your vet. Lumps in this location can be any of these things: * abscess (infection) * cyst * cancer (benign or malignant) * rodent ulcer I suggest you find a vet to take him to for an examination. There are no home treatments for any of these possibilities. Also, treatment depends on what the lump is - all those possibilities have different treatments.

My 11-year-old cat has a mouth lump and ear bumps. Is it serious?

Thanks for using Petco Pet Education Center, formerly Petcoach! These could be benign or malignant growths. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Moo evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

Should I worry about a small bump on my cat's lower mouth not growing?

Hello. I would just watch this for now. I have removed several of these off of older cats, & they are most often benign & not dangerous. Removal is always curative. If it looks like it is enlarging, or it is interfering with his ability to eat or chew, definitely consider having it removed. Otherwise, just monitor for now.

My senior cat has a black hard lump on her lip. Is it cancer?

The most common causes of oral tumors in cats are melanoma, squamous cell carcinoma and fibrosarcoma. A black tumor would be more suspicious of melanoma. In either of these cases, you want to get it removed and identified soon, because they are all cancerous. However, there are many benign (non- cancerous) causes of nodules in the mouth, so don't worry too much yet. A veterinarian may see it and not be as concerned based on the appearance. I hope that helps and all turns out OK with Alexis.

Painless dark lump on my senior cat's skin: Is it a lipoma or tumor?

It could be a lipoma, but unfortunately in a senior cat like Leia it could also be a malignant tumor. Other possibilities include a cyst, abscess, or benign tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Leia seen by a vet tomorrow to have this lump examined and diagnosed so it can be treated as needed.

My cat has a black bump on her inner lower lip. Is it normal?

Congrats on your new cat! This bump on Arya could be from an injury or it could be a benign tumor. It would be a good idea to have it checked out by a vet just to make sure there is nothing concerning about it. The vet can let you know if it needs to be treated or not.
