Hi. My princess is 6 and has a mammary tumor the size of a golf ball. The vet said I can do surgery but it can be risky. I had her cagemate that had some custand they opened up and she died the next day. She is happy and her self but the tummor does rub on the floor. Any sugestiond?
Thanks
 
Hello and welcome to the forum
If the tumour is not connected to any organ then it’s a fairly straightforward operation, my Bill had a small mammary tumour remove with no problems at all. he was 4 years old at the time. The bigger risk to probably thr anaesthetic with her age, but if you vet is experienced and she is overall healthy then the risks are greatly reduced. The problem with tumours is they can ulcerate and if they become infected this can be quite serious and difficult to treat, especially areas that rub along the ground

Hi

I am very sorry.

Unfortunately, the thing about mammary tumors is that they just continue to grow and to grow and to grow until the legs can no longer touch the floor and then they continue to grow. :(
Mammary tumors can be both benign or malign but are generally not too bad to operate out as long as they are still encapsulated.

It means that you have to either face a make or break operation or euthanasia . It is unfortunately one of these horrible 'between a rock and a hard place' situations where there is no easy way out and the choice is between two rather difficult options. In terms of an operation, it all hinges on your vet's confidence and practical experience in operating on small furries. I know of a number of mammary tumor ops that have come off well, even where the tumor was already quite large. :(

I REALLY wish I had better news; especially at this time of year. At least you can be proud that your girl has lived to a good age.
 
I hope your vet is experienced in operating on piggies. If she is otherwise well in herself I think I would opt for the operation to give her a chance before it gets too big and sore. If she unfortunately doesn’t make it at least you know you tried everything. Good luck. The flip side is you give her as many happy days now. She’s a fantastic age so is obviously very well cared for and loved. 😍
 
I am sorry for the predicament you find yourself in :( Sadly, if left, the tumour will just grow and grow causing difficulties further down the line especially if it is already rubbing on the ground :( My Edward is 6 too and has a lump in his neck. Fortunately it's a harmless fatty lump which we have decided to leave as it isn't causing him any problems but I wouldn't hesitate to have it removed if it had of turned out to be something more serious. My Elizabeth is around 3 and has small lumps all over her belly including one near her nipple. They're all harmless fatty lumps that we have been advised to leave alone but she may need them removing in the future if they grow and impact her mobility. The final decision has to be yours though, go with your heart and whatever decision you decide will be the right one x

Is your vet absolutely sure that it is a tumour?
My sow Winifred had a mammary lump, my regular vet assumed it was a tumour and said nothing could be done. A different vet said it might not be, and when it was tested after removal it was found to be benign.

Your girl's lump still needs removing though so there is still that issue... Any surgery has risks, especially in older piggies, you can try to reduce the risk by using a vet who has plenty of experience removing lumps. If you feel the risk is still too high, the alternative is palliative care to keep her comfortable for as many happy today's as may be. Wishing you luck! :hug:

Thank you so much. Let me see if I can attach a photo and you can tell me what you think

Thank you so much. It is so hard to decide because mentally she’s still her old normal self and my vet said they never lost a guinea pig to anesthesia before. She’s healthy but overweight. The only thing it concerns me is that the vet said since she’s not spayed which I didn’t think of doing it since her cage mate was a female is that most likely more will grow so how many surgeries can we put my baby thru
 
Hi!

It looks very uncomfortable to me. :(
I know. I responded to the other comment about my vet saying that since she’s not spayed most likely more will come and how many surgeries can a baby go thru. This is a new vet. I just moved to Georgia from Florida so she said she hasn’t lost a piggy in 15 years but another vet 1 year ago where I took the cagemate when I first moved here opened a cyst on her and she died the next morning. It’s so hard to decide

I can’t add any advice, except to say go with your heart.
Holding you in my thoughts
Thank you

I have so far not come across a mammary tumor growing back on here.

Ouch that looks sore. Poor thing. 6 is definitely senior but she could get to 8! So if she’s healthy in general she should be ok. A lump that size must be so uncomfortable for her. Good luck at the vets.
 
Aw that’s a large lump. Bill’s was much smaller less than a cm but the vet did find another tiny one just behind it so he said it was very aggressive and starting to spread. Mammary umours can be aggressive or benign, our vet said certain mammary tumour can be worse in male piggies as they haven’t go the defensive hormones female have. It never came back and he recovered so well, he had a 300 mile journey back home that day too as we go to the Cat and Rabbit Clinic for a surgical procedures as they are such good vets.
It’s a really hard choice to make and I can fully understand how difficult it is. I think the main thing is having a very experienced vet on board that you can be guided by x

Aw poor piggy, that does look sore and uncomfortable :( It’s a hard decision to make but as said, she could have a few years left in her yet. All the best with whatever you decide x
 
I would definitely proceed with surgery - that must be causing discomfort and irritation to her. I took in (for the rescue) a piggy with a mammary tumour that had been allowed to grow large over a period of time and had then burst. As a result she required a larger excision than if it had been removed at a smaller size. She made a good recovery (after a second surgery to re-suture the area after she decided to remove all her sutures!) and was successfully rehomed with no issues to my knowledge.

Thank you. We will take her to the vet next week. Meanwhile we’re giving her pain meds that the vet gave us

Sorry, I should have been clearer. Winifred's lump wasn't a tumour, benign or malignant. Tests showed it to be a granuloma or steatitis, growth produced by the body in response to an "insult" the vet said. The mass was neat and straightforward to remove.
I was trying to say that your girl's mass might not be a tumour, with all the worrying implications they have, unless your vet has already confirmed it with a lab test.
Sending healing vibes to Princess, whatever you decide to do xx

You helped a lot. That’s my fear. It’s making a decision without 100% certainty. In 4 days we go see a second vet for another opinion. Hopefully that gives me clarity.
Thank you so much for your help
 
Hi. Follow up on princess. Since she’s 6 and having her mass removal is it worth to spay her at this age?
Thanks
