In the event of onset of chondrosarcoma, you may feel a localized pain in the bones of the legs, pelvis or arms, the intensity of which may vary between being either dull or becoming extreme especially during rest. However, it can occur in any cartilaginous part of the body. The intensity usually progresses to become more painful over time. You may also feel swelling in the area marked by pain. Upon physical examination, you may be able to feel a mass or a lump, which puts pressure on the adjoining bones and area. You may experience limited movement of the affected limb owing to tumour enlargement. In the case of the cancer affecting your bones to the extent of weakening them, you may suffer a bone fracture due to a mild injury that might be symptomatic of chondrosarcoma.
