My 5 year old piggu died today because of a tumor and I'd just like to notify you all to check on your beloved pets. If guinea piga don't breed, there is a chance they might get a tumor, so if you notice their belly getting big make sure to take them to the vet. I was never told about this and I thought she was just getting fat from food, until she started bleeding. When I took her to the vet they said she needed an operation and that it's a very serious matter, the tumor was almost her own size. She woke up after total anaesthesia which is a miracle, since it's very risky with small animals. I warmed her up, gave her water and food, she started moving and it was going for the better. I was waking up every 2 hours at night to check on her... In the morning she started shaking uncontrollably and then passed away. She meant so much to me, and if I knew earlier, I could have prevented it. Please take care of your pets and check on them regularly!
Hi! I am very sorry for your loss and the heartbreak it is causing you. Internal tumours are never good news and losing a piggy to an unexpected problem can be a traumatising experience. Unfortunately, it sounds like your tumour was already very advanced when it was seen by a vet.
Ovarian cysts can in some cases become cancerous. In this case, removal of the cysts or a full spay is the usual line of treatment.
If you are worried about ovarian cancer in any future sows, then a spaying operation is what you want to have done, but definitely NOT exposing any sow of yours to the risk of miscarriage or dying from common birthing complications and the heart-break of dead-born or dying pups.
Sadly your advice is one of the several persistent breeder myths that have long since debunked that you have fallen victim to with your 'warning'!
Please be aware that even mothers can still develop ovarian cysts (including cancerous ones), as my own Iola is just one first-hand example for; she was dumped into a (bad) rescue after a teenage pet shop or breeder pregnancy long before she found her way here. Iola had a successful spaying operation for large non-hormonal ovarian cysts aged 5 and lived for over a year long to the good old age of 6 1/2 when she died from unrelated causes.
You need to also be aware that giving birth doesn't in any way influence the formation of any other internal tumours that can affect all piggies of any gender and irrespective of whether they are de-sexed or not, or have had babies or not. These tumours are much more likely caused by sprayed foods and the pervasiveness of chemicals in our daily lives, as well as genetic disposition or a combination of these.
Please accept that we are a strictly non-breeding forum and won't change our stance, seeing that there is a 20% risk of fatality in every single birth under the best conditions (the risk is going up even higher in all others!), which is on balance a MUCH higher risk of life than the chance of developing cancerous ovarian cysts or internal tumours. If you think that a tumour is traumatising, then dealing with dead and dying babies or a dying new mother/mother-to-be in serious discomfort is even more so, I can assure you!

You are welcome to check for yourself just how much death and heart-break our pregnancy section for unplanned births from mis-sexed or already pregnant shop and breeder piggies is littered with.
You are also welcome to check through our health/illness section, which is going back 12 years, as to the frequency of cancerous ovarian cysts in the tens of thousands of piggies that have passed through this section compared to birthing operations. Our health/illness section is not the worst mirror as to which problems are the most frequent and the most deadly ones.
