Bone tumor
Tumor - bone; Bone cancer; Primary bone tumor; Secondary bone tumor; Bone tumor - benign
A bone tumor is an abnormal growth of cells within a bone. A bone tumor may be cancerous (malignant) or noncancerous ( benign ).
Tumor
A tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (benign).
Benign
"Benign" refers to a condition, tumor, or growth that is not cancerous. This means that it does not spread to other parts of the body. It does not ...
Causes
The cause of bone tumors is unknown. They often occur in areas of the bone that grow rapidly. Possible causes include:
- Genetic defects passed down through families
- Radiation
- Injury
In most cases, no specific cause is found.
Osteochondromas are the most common noncancerous (benign) bone tumors. They occur most often in young people between the ages of 10 and 20.
Cancers that start in the bones are called primary bone tumors. Cancers that start in another part of the body (such as the breast, lungs, or colon) are called secondary or metastatic bone tumors. They behave very differently from primary bone tumors.
Cancerous primary bone tumors include:
- Chondrosarcoma
-
Ewing sarcoma
Ewing sarcoma
Ewing sarcoma is a malignant bone tumor that forms in the bone or soft tissue. It affects mostly teens and young adults.
- Fibrosarcoma
-
Osteosarcomas
Osteosarcomas
Osteosarcoma is a very rare type of cancerous bone tumor that usually develops in teenagers. It often occurs when a teen is growing rapidly....
Cancers that most often spread to the bone are cancers of the:
- Breast
- Kidney
- Lung
- Prostate
- Thyroid
These forms of cancer usually affect older people.
Bone cancer is more common in persons who have a family history of cancers.
Symptoms
Symptoms of bone tumor may include any of the following:
- Bone fracture, especially from slight injury (trauma)
-
Bone pain
, may be worse at night
Bone pain
Bone pain or tenderness is aching or other discomfort in one or more bones.
- Occasionally a mass and swelling can be felt at the tumor site
Some benign tumors have no symptoms.
Exams and Tests
The health care provider will perform a physical exam. Tests that may be done include:
-
Alkaline phosphatase
blood level
Alkaline phosphatase
Alkaline phosphatase (ALP) is a protein found in all body tissues. Tissues with higher amounts of ALP include the liver, bile ducts, and bone. A blo...
-
Bone biopsy
Bone biopsy
A bone lesion biopsy is the removal of a piece of bone or bone marrow for examination.
-
Bone scan
Bone scan
A bone scan is an imaging test used to diagnose bone diseases and find out how severe they are.
- Chest x-ray
- CT scan of the chest
-
MRI
of the bone and surrounding tissue
MRI
A magnetic resonance imaging (MRI) scan is an imaging test that uses powerful magnets and radio waves to create pictures of the body. It does not us...
-
X-ray of bone
and surrounding tissue
X-ray of bone
A bone x-ray is an imaging test to look at the bones.
- PET scan
This following tests may also be ordered to monitor the disease:
-
Alkaline phosphatase isoenzyme
Alkaline phosphatase isoenzyme
Alkaline phosphatase (ALP) is an enzyme found in many body tissues such as liver, bile ducts, bone, and intestine. There are several different forms...
- Blood calcium level
-
Parathyroid hormone
Parathyroid hormone
The PTH test measures the level of parathyroid hormone in the blood. PTH stands for parathyroid hormone. It is a protein hormone released by the par...
-
Blood phosphorus
level
Blood phosphorus
The phosphorus blood test measures the amount of phosphate in the blood.
Treatment
Some benign bone tumors go away on their own and do not need treatment. Your doctor will closely monitor you. You will likely need regular imaging tests, such as x-rays, to see if the tumor shrinks or grows.
Surgery may be needed to remove the tumor in some cases.
Treatment for cancerous bone tumors that have spread from other parts of the body depends on where the cancer started. Radiation therapy may be given to prevent fractures or to relieve pain. Chemotherapy may be used to prevent fractures or the need for surgery or radiation.
Tumors that start in the bone are rare. After biopsy, a combination of chemotherapy and surgery is usually necessary. Radiation therapy may be needed before or after surgery.
Support Groups
You can ease the stress of illness by joining a cancer support group . Sharing with others who have common experiences and problems can help you not feel alone.
Cancer support group
The following organizations are good resources for information on cancer:American Cancer Society -- www. cancer. orgCancerCare -- www. cancercare. or...
Outlook (Prognosis)
How well you do depends on the type of bone tumor.
Outcome is usually people with noncancerous (benign) tumors. But some benign bone tumors can turn into cancer.
People with cancerous bone tumors that have not spread may be cured. The cure rate depends on the type of cancer, location, size, and other factors. Talk to your doctor about your particular cancer.
Possible Complications
Problems that may result from the tumor or treatment include:
- Pain
- Reduced function, depending on the tumor
- Side effects of chemotherapy
- Spread of the cancer to other nearby tissues (metastasis)
When to Contact a Medical Professional
Call your provider if you have symptoms of a bone tumor.

X-ray - illustration
X-rays are a form of ionizing radiation that can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray depending on density. X-rays can provide information about obstructions, tumors, and other diseases, especially when coupled with the use of barium and air contrast within the bowel.
