There are often few symptoms indicating that you have developed a soft tissue tumor or bone tumor. Such symptoms can also also be indicative of another, noncancerous ailment. It is important to see a doctor about any physical changes you notice in your body, such as a lump or mass, because only a doctor can make a diagnosis.
Soft Tissue Cancer
Soft tissue malignant tumors (sarcomas) usually appear as a lump or mass. They do not commonly cause pain, swelling or other symptoms. A lump or mass might not be a sarcoma; it could be benign (noncancerous), a different type of cancer or another medical problem.
Pain is the most common symptom of bone cancer, although not all malignant bone tumors cause pain. Persistent or unusual pain or swelling in or near a bone can often caused by a bone tumor or by other conditions. Consult with your physician for a diagnosis.
