Tumor types
Are there differences among tumors?

The behavior and treatment of cancer can vary between tumor types, between tumor stages and between patients with the same tumor type and stage. In order to properly fight a tumor, specific information is necessary. The more is known about the tumor, the better it can be treated.

For example, your dog may have a bone tumor with an unknown origin. The mass can originate from bone (osteosarcoma), cartilage (chondrosarcoma) or even be a metastasis towards the bone (as can be the case for eg a prostate carcinoma).

The behavior of an osteosarcoma is far more aggressive than that of a chondrosarcoma and requests a different approach. For these reasons it is important to detect this difference. Tumors can be differentiated via the study of their tissue (histopathology) for which a biopsy can be taken, or cells (cytology) for which a needle can be inserted into the mass and the retrieved cells examined under a microscope.

Via medical imaging (radiography, CT/MRI scan, ultrasound, scopy, etc.) information can be gathered about where precisely the tumor is situated. This facilitates the treatment planning for surgery and/or other treatments, which reduces the risk of relapse.
