On What Are The Four Main Types of Dog Bone Cancer? Part 2, we discussed Chondrosarcoma. This time, we’ll talk about Fibrosarcoma.

The type of bone cancer called Fibrosarcoma is rare. It is responsible for less than 5% of the primary types of bone tumors. It comes from the fibrous connective tissues (hence the name) that are found in the ribs, spine, pelvis, and skull. It can however come from any bone type.

Even dogs can get bone cancer.

It is a non-osteosarcoma bone type, but it is still very difficult to set it apart from the very common osteosarcoma or OSA, specifically what they call fibroblastic osteosarcoma. There are two varieties of this tumor type: Central, and Parosteal.

Fibrosarcoma Treatments

Main treatments for Fibrosarcoma involve amputation, limb salvage and surgical resectioning. Radiation therapy can be applied as alternative pain relief in some special instances. There is chemotherapy to threat the rare instance that cancer spreads, and pain medication.

Why fibrosarcoma develops is still unknown because it is a rare tumor type. It is found more commonly in older male canines, but there is a variety that develops in the mouths of younger dogs.

Symptoms of Fibrosarcoma

These can be signs that a dog has fibrosarcoma:

  • lameness or pain in the legs or limbs
  • dog has a hard time swallowing or eating
  • strange and unexplained swelling in any bones
  • bleeding in or from the mouth, and a foul odor from the mouth
