Anyone hear about similar symptoms - 2 females with ongoing URI both grow mammary tumor in one week ?

Hi Everyone, I am desperately looking for anyone who have seen similar symptoms and could help. We have 3 female guinea pigs (Abyssinian, smooth and Rex), all 2.5 year old living together. 3 weeks ago they all started sneezing, Winnie more than two others - Bramble and Honey. Winnie had also slightly crusty eye. Winnie was sneezing every 15min and others twice in a an hour.

Vet prescribed Bactrim for all 3. After 7 days on Bactrim they were slightly better and sneeze once in a few hours. Eye was almost normal. Vet advice to take Bactrim 7 more days. After 3days I call him again telling that they are slightly worse Winnies eye more crusty again, more sneezing, small discharge form the nose) and Honey now had one eye red and swollen slightly. Vet changed med. to Baytril for all but low dose 0.2ml (2.5%oral solution). It helped again - slightly only, after 7 days dose was changed by another vet to 0.5ml (my pigs are around 1.3kg each).

After 6 days they were getting much better, Bramble (the only one whiteout eye infected) looks healthy (no sneezing no other symptoms), Winnie sneezing once in a 2 hours, Honey no sneezing and eye almost looks normal. And then we noticed Winnie has a large lump under her nipple, the size of a flat walnut. We are sure it wasn't there week ago as we were checking on his tummy then (me not vet as all consultations were by phone due to Covid), or it was very small. It grow really fast. I have checked other piggies they were ok. I was last night.

Today Winnie (and only she as others look healthy) was in the clinic and vet said it is probably mammary tumor and needs to be removed. They booked surgery for Thursday. We were shocked, sad but hopeful. Winnie and Honey were left on Baytril, Honey till Monday to make sure the eye looks good and Winnie until surgery).

Tonight I have checked on Winnie and she has a small tumor in the same place where Winnies, just under right nipple. I am almost sure it wasn't there 36 hour ago. Don't know how explain this. Why they are both having exactly the same symptoms including tumor. Tumor looks not painful as they not care about touching it, the skin around look normal, no redness, no signs of infection on the skin - just lump.

The last 3 weeks they all were energetic as always, eating a lot, pooping normal, chasing and bossing each others. No change in anything. Winnies tumor looks bigger than yesterday so its visibly growing. Yesterday was softer and more loosely moving under the skin, now more attached and harder, more round/full. I have separated healthy Bramble from others and will call vet Monday morning.

Now I am looking what connection could be between respiratory infection symptoms and mammary tumors and cant find anything about guinea pigs. If anyone hear anything similar or had similar experience I will be very very grateful!

ps. I am sorry for my grammar, English is not my first language, hope its readable.

You write excellently. I had no problem following your description.

I do not know of any connection between a URI and mammary tumor. Sometimes due to the timing of an illness, it can seem like it is related but it would only seem so if it was not a mammary tumor but instead was some sort of infection that had moved to that area. I don't recall anyone reporting an infection that might be mistaken for a mammary tumor.

When the tumors are removed, you could (if you wanted to) have a biopsy done of the tumor to gain more information. A biopsy would rule out an infection. One would think the antibiotic you have been giving would treat an infection.

I tend to think this is simply a coincidence.

Thank you Lynx, I was thinking also that maybe this is not a mammary tumor? Vet only checked Winnie and only by looking on her, (he said he is suspecting its mammary tumor) no test was done as we agreed it needs to be removed. He wasn't specialist on guinea pigs (he had some experience but not on surgeries and less than vet who will be doing surgery on Thursday). I am trying to find if its anything else which could cause symptoms like URI and lupms in mammary area. Their URI is stubborn but not severe, they were mostly sneezing Winnies very small nose discharge is now gone. no breathing problems, no lost of appetite, and they are active as normal, fur looks good as always. I will try to consult on Monday with vet who will be doing surgery, until then hoping to find some clues, if there is any other illness than tumor causing this kind of symptoms I could ask for some tests etc.

It is very reasonable to diagnose it as a mammary tumor. I think a quick check to perhaps confirm that could be done with a fine needle aspiration to see what is inside the lump.

Today is surgery day. The earliest news will be at 1.30pm. Please keep Winnie in your thoughts.

I absolutely will. I know how nerve-wracking it is to wait to hear from the vet. Do let us know how it goes.

In the meantime, if you haven't already read this, there is some very helpful info on post-op care here:

Usually this type of surgery goes pretty well. It is not as invasive as stone removal, for example.

Hoping for a positive update after the surgery!

Thank you all for kind words, we are in a huge stress. The surgery was planned before lunch time. At 1.30 they told me it will start in a minute and update will be in hour but 1 hour later it still didn't start. Now they promised to call me when it will be finished. I am worried if they fed her or gave her water (I gave them a bag of her favourite food but dont know if someone actually fed her, they sound chaotic and busy today. Lump was slightly larger than few days ago and she was still sneezing (4th week on antibiotics, 2nd week on Baytril) but on the positive side Winnie was active and eating and pooping as normal. She even weight 15g more than a week ago. And she tolerate Baytril very well and this is what they planned give her after surgery as an injection.

They may have had an emergency case to deal with that threw their schedule off. I wouldn't think they would feed her before the procedure; if anything, most vets are very conservative about feeding before surgery---sometimes more than they need to be, where guinea pigs are concerned.

Hang in there.

Winnie is home again. Stitching's look clean and nice (I will make a photo tomorrow). I was told the lump was kind of contained in the "capsule" and therefore easier to remove (it was large). Winnie was scared but start eating salad 5 min after she came back to her cage. she ate quite a few leaves, rest and walk to the hay rack and pellets and herb bowl. Eating a lot / all the time, pooping/weeing normally. She is walking slowly and you can see discomfort while sitting but we are proud how brave she is!
Still sneezing and her eyes look watery. Honey - second guinea pig with smaller lump already booked for vet consultation next Wednesday (probable surgery soon after).

Very brave girl! I'm so glad she seems to be recovering well from the anesthesia. Did they give you any pain meds to use if needed?

Unfortunately no painkillers, I have asked for some but vet said she got some during surgery and will no need more. She looks like in some pain but also walking from time to time for food around the cage.

I was advised by vet to buy the nebuliser for stubborn URI treatment. Could anyone advise me please which machine is the best? I found few but have no clue what parameters it should have?

If you feel a nebulizer would make a big difference, I would go with the first one pictured (first link is just a link), assuming each would indeed function fine. It is the least expensive. It is not important to have a special mouthpiece or face covering if you choose instead to create a sealed plastic box with a round hole in it to stick the nebulizer nozzle in to administer whatever drug you are giving while the guinea pig is nestled in the box.

I did not read the specifics of each machine but assume they function equally.

I have ordered it and thank you for the advise - I had a look how the whole set up looks with the plastic box and it shouldn't be a problem (I thought at first I will need to hold her with the head in the face covering the whole time and couldn't imagine that be easy)
