Bone cancer is a disease marked by the uncontrolled growth of bone cells. Primary bone cancer, which originates in the bone, is rare; most bone cancer results from the spread of cancer from other tissues. Different bone tissues can give rise to different types of primary bone cancer. Osteosarcoma comes from cells that form bone, and Ewing sarcoma comes from immature nerve tissue within the bone. Chondrosarcoma forms in cartilage tissue. Symptoms include pain or tenderness over the affected bone, fractures, reduced joint mobility, fever, fatigue, and anemia. Diagnosis involves blood tests, X-rays, CT scans, MRI, and bone scans, but final confirmation requires microscopic examination of a tumor sample. Treatment options include surgery, chemotherapy, and radiation.

How does bone cancer affect the body?

Bone cancer disrupts normal bone function through uncontrolled cell growth. While primary bone cancer is rare, it can develop from different bone tissues. Osteosarcoma and Ewing sarcoma affect bone-forming cells and immature nerve tissue, respectively, while chondrosarcoma arises in cartilage tissue. Symptoms include pain, tenderness, and fractures. As bone cancer advances, the amount of alkaline phosphatase, an enzyme, in the blood increases. Bone tumors can cause abnormalities observable in X-rays as defects in the bone tissue. Treatment approaches, such as surgery, chemotherapy, and radiation, depend on the cancer's type, size, location, and spread. Radiation therapy can also cause long-term damage to bone tissue.

What are common symptoms of bone cancer?

The most common symptom of bone cancer is pain or tenderness over the affected bone. Bone tumors are often unnoticed until minor trauma causes significant pain and disability that leads to further investigation. Other symptoms include bone fractures, decreased joint mobility, fever, fatigue, and anemia. These symptoms are not specific to bone cancer and can result from other benign processes. Other signs of a bone tumor are pain, swelling, and fracture that is spontaneous or caused by only trivial forces. Most bone tumors cause abnormalities observable in X-rays as defects in the bone tissue.

How do doctors diagnose bone cancer?

Doctors use multiple methods to diagnose bone cancer . Initial tests include blood work to check alkaline phosphatase levels, which increase with bone cancer growth, and imaging techniques like X-rays, CT scans, MRI, and radioisotope bone scans to visualize bone tissue changes. However, a definitive diagnosis requires a biopsy , where a tumor sample is examined under a microscope.

What treatments are available for bone cancer?

Typically, bone cancer treatment involves a combination of surgery , chemotherapy , and radiation , but it depends on the type of cell, location, size, and spread of the primary tumor. In some instances, surgery may require limb amputation. However, it may be possible to remove only a portion of the bone and replace it with a prosthesis or bone graft . Chemotherapy may be administered before or after surgery and is tailored to the specific type of bone cancer. Targeted therapy is a treatment that uses drugs to attack specific molecular anomalies driving cancer cell growth while leaving healthy cells unaffected. Immunotherapy is a medical treatment that uses the body’s own cells or chemicals to help the natural immune response work against disease.

How can bone cancer impact a person’s life and health in the long term?

Bone cancer can significantly impact a person’s life and health in the long term. While most cases appear randomly in healthy individuals, exposure to radiation or chemotherapy and hereditary syndromes are known risk factors. The prognosis of bone cancer depends on the type and how far it has spread. Bone cancer can spread to the lungs and other bones. Treatment includes surgery, chemotherapy, and radiation. Radiation therapy can cause long-term side effects, such as hormone deficiencies, learning difficulties, and secondary malignancies like thyroid, breast, or lung cancer. In children, radiation can affect bone growth, leading to deformities. The most common symptom is pain or tenderness over the affected bone. Osteosarcoma, the most common bone cancer, can cause pain, swelling, limited joint motion, and fractures.

bone cancer, disease characterized by uncontrolled growth of cells of the bone. Primary bone cancer—that is, cancer that arises directly in the bone—is relatively rare. In the United States, for example, only about 3,600 new cases of primary bone cancer are diagnosed each year. Most cancer that involves the bone is cancer that has spread (metastasized) from other tissues in the body through the blood or lymphatic systems. Different types of bone tissue give rise to different types of primary bone cancer. Osteosarcoma develops from cells that form the bone, and Ewing tumour of the bone (Ewing sarcoma) develops from immature nerve tissue within the bone. Both types most commonly affect males between 10 and 20 years of age. Chondrosarcoma, which forms in cartilage tissue, principally affects persons over age 50. More than one-half of the cases of primary bone cancer, even once-deadly types, can now be treated successfully.

Causes and symptoms

Only a small portion of bone cancer cases are associated with known risk factors, which include exposure to radiation or chemotherapy, Paget disease, and rare hereditary syndromes such as hereditary retinoblastoma. The majority of cases seem to occur randomly in otherwise healthy individuals.

The most common symptom of bone cancer is pain or tenderness over the affected bone. Bone tumours often are not noticed until minor trauma causes significant pain and disability that leads to further investigation. This association has led to the mistaken conclusion that traumatic injuries can cause bone cancer. Other symptoms that can occur include bone fractures, decreased mobility of a joint, fever, fatigue, and anemia. These symptoms are not specific to bone cancer and can be the result of other, benign processes.

Diagnosis and prognosis

Preliminary investigation of a bone tumour can include a blood test for the enzyme alkaline phosphatase. As bone cancer grows, the amount of the enzyme in the blood increases dramatically, but it can also increase for other reasons. With bone cancer, unlike many other types of cancer, X-ray imaging can be very helpful in making a diagnosis. The images will show whether a tumour is creating bone tissue or destroying normal bone tissue. Images of the bone useful for making a diagnosis can also be obtained by computed tomography (CT scans), magnetic resonance imaging (MRI), and a type of radioisotope scanning commonly called a bone scan. The final diagnosis of cancer, however, requires the removal of a portion of the tumour for examination under a microscope.

The prognosis of bone cancer depends on both the type of cancer and the extent to which it has spread. Bone cancer most frequently spreads to the lungs, but it may also spread to other bones and only rarely to other tissues. Overall, the prognosis for long-term survival has improved to more than 50 percent, including cases in which the tumour has spread to other parts of the body. Of the different types of primary bone cancer, chondrosarcoma has the best prognosis and osteosarcoma the worst.

Treatment

As with many cancers, the treatment of bone cancer depends on the type of cell, location, size, and spread of the primary tumour. Most cases require a combination of surgery, chemotherapy, and radiation. In some cases, surgery requires the amputation of the involved limb. In other cases, it may be possible to remove only a portion of the bone and replace it with a prosthesis or bone graft. Chemotherapy may be given before or after surgery and is tailored to the specific type of bone cancer.

Prevention

Prevention of bone cancer will require a better understanding of its causes than is currently available. If a patient has a known risk factor for bone cancer, such as Paget disease, careful screening may help detect and treat the cancer in its early stages, thereby improving the chances for survival.
