Bone Tumors ----------- General Information Bone tumors may be non-cancerous (benign) or cancerous (malignant). Benign (non-cancerous) tumors are those that do not spread to other parts of the body; these tumors are the less dangerous type. Malignant (cancerous) tumors can spread and are much more dangerous. Most bone tumors are cancerous and are usually painful. Therefore, a prompt decision for surgery is required to relieve discomfort and to increase the chances for a successful outcome. Important Points in Treatment 1. Some types of bone tumors require considerable personal and economic commitment by you, the owner. The doctor will assist you in any way possible to arrive at an acceptable decision on how far to pursue treatment. 2. A complete physical examination, usually including laboratory tests, radiographs (x-rays) and biopsies (the microscopic examination of tissue samples), may be required for diagnosing and evaluating your pet's condition. 3. Your pet may be referred to a cancer specialist for further evaluation and/or treatment. 4. Surgery, irradiation, chemotherapy or a combination of these are used to treat bone tumors.
