Cancers and Tumors in Guinea Pigs



Your veterinarian will likely recommend surgical removal of the tumor or cancer. In some cases, with benign tumors, the growth may be impeding blood flow or the normal functions of the surrounding internal organs. If the benign tumor is not affecting the body in a negative way and is not expected to grow, your doctor may allow for it to be left alone.


In cases of malignant growths, surgery may be necessary, but may not always be possible if the location is in a place of the body where surgery would do more harm than good, or if disturbing the tumor would release the cancer cells to spread more quickly into the body.


For skin tumors like trichoepitheliomas, surgical removal is routinely done. Treatments for leukemia or lymphosarcoma, on the other hand, are not viable options and the animals usually die a few weeks after the symptoms have become apparent.


Living and Management


A pet guinea pig that is recovering after tumor surgery needs attentive postoperative care, with adequate rest in a quiet environment for recuperation. Regular follow-up visits to your veterinarian will be necessary to follow your guinea pig's recovery progress.




There is no way to prevent tumors and cancers in guinea pigs.
