What the heck are these?! Fret not, as it is not some alien parasite out to get the animal kingdom to the brink of extinction.
The deer actually have fibromatosis. Simply put, it refers to a group of harmless soft tissue tumors. Its growth pattern is infiltrative, and it can negatively affect both fat and skeletal muscles. More importantly, fibromatosis can be observed in both humans and animals, so do be careful -- treatment primarily requires surgery. The good thing, at least, is that the mortality rate is very low for those who have peripheral tumors.
Fibromatosis is a common disease among deer.
Bucks and those no less than two years of age are likely to develop fibromatosis.
Fibromatosis in deer do not affect humans.
Deer with such tumors can live unaffected by it and wait for them to regress, but these ones affect the vision of the animal.
Fibromatosis are not a likely cause of death of deer.
Aside form blocked vision, fibromas on the face can affect how a deer chews and swallows.
Aside from the neck, fibromas are commonly found on the eyes, face, and forelegs.
Through research, it has been noted that deer have an immune response to fibromatosis, thus effectively limiting the disease.
Moreover, its meat is not contaminated by the disease, but aesthetically it's deemed repulsive by many people.
Deer with fibromatosis can be found in Michigan, Isle Royale, and British Columbia.
Insects who bite deer may be responsible for the disease.
Typically, the tumors are about 5-inches long.
The presence of tumors can cause stress or indirect injuries to the deer.
Fighting among bucks may contribute to the transmission of fibromatosis.
It is still not entirely known how the disease is transmitted, though experiments are being conducted.
