Question:

Is a biopsy worth it? Potential mouth cancer in cat

I'm at a bit of a crossroads and could really use some advice from fellow pet parents who might've gone through something similar. My 12-year-old cat, Whiskers, has recently been having some trouble eating and drooling more than usual. I took him to the vet, and they suspect it might be mouth cancer. They've recommended a biopsy to be sure, but the cost is significant, and I'm worried about the stress it might put on him. To be honest, I'm scared of the results but also don't want to leave him in discomfort if there's something we can do. Has anyone here had experience with this sort of situation? How did your cat handle the biopsy, and was it worth it in the end? I'm just feeling so lost and anxious right now and could use some guidance. Any thoughts would be greatly appreciated!

Answer:

Hello there,



I can understand why you're concerned about your cat's potential mouth issues. Deciding whether to proceed with a biopsy can be a big decision, but it's often an important step in getting a clear diagnosis. Mouth cancer in cats can manifest in various forms, such as lumps, sores, or even changes in eating habits or weight loss. These symptoms can also be caused by less serious conditions like dental diseases or infections.



A biopsy is a procedure where a small tissue sample is taken from the area of concern. It’s usually a straightforward and minor procedure under anesthesia or sedation. The sample is then analyzed to determine if cancer cells are present or if another issue is responsible.



While waiting for a biopsy or a vet visit, ensure your cat is comfortable. You can offer soft foods or moistened kibble if chewing seems painful. Keep an eye on any changes or worsening symptoms like bleeding, drooling, foul odor, or difficulty eating, as these can indicate a need for more urgent care.



Please consider scheduling a video consult with one of our vets at Dial A Vet to discuss your concerns further. They can provide guidance tailored to your cat's specific situation and assist you in making the best decision for your furry friend.

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
