Vaccine-associated rhabdomyosarcoma

evidence-based cancer treatment — the discipline that insists on proof that time-honored medical practices and procedures are actually effective.
No ancedotal stuff please.
Pet cancer treatment can cost ten thousand USA dollars. This forum is for people to tell us how they were able to obtain cancer treatment when they had no pet health insurance to cover the cost. Rabie Vaccine caused cancer often is paid for by the company that produced the vaccine even when not legally required to do so.

Abstract
A 7-year-old, female, domestic medium-haired cat had a recurrent deep dermal mass in the interscapular region after initial surgical removal 3 months earlier. The cat had received a killed rabies vaccine and a five-in-one vaccine in the same area about 2 months prior to the first surgery. The relapsed mass was diagnosed as vaccine-associated sarcoma. The cat was euthanized 2 months later because of hind limb paralysis. At necropsy, multiple, poorly demarcated, nodular masses were seen in the muscles around the shoulders, neck, and thoracic vertebrae. Pulmonary metastasis and spinal epidural invasion at T1-T3 with regional cord compression and malacia were observed. Microscopically, the masses consisted of interwoven bundles of spindle cells with prominent multinucleated giant cell formation. The neoplastic cells stained strongly positive for myoglobin, and moderately but variably positive for vimentin, desmin, and alpha- smooth muscle actin. Phosphotungstic acid-hematoxylin staining revealed cytoplasmic striations in scattered tumor cells. The tumor was considered a vaccine-associated rhabdomyosarcoma.
