Tumor
A tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (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 in...
Read Article Now Book Mark ArticleCauses
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. Bone 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.
Metastatic
Metastasis is the movement or spreading of cancer cells from one organ or tissue to another. Cancer cells usually spread through the blood or the ly...

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 people who have a family history of cancers.
Symptoms
Symptoms of a 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.

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...

Treatment
Some benign bone tumors go away on their own and do not need treatment. Your provider 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.
Radiation therapy
Radiation therapy uses high-powered radiation (such as x-rays or gamma rays), particles, or radioactive seeds to kill cancer cells.

Read Article Now Book Mark ArticleTumors 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. Support and online communities. www. cancer. org/...
Read Article Now Book Mark ArticleOutlook (Prognosis)
How well you do depends on the type of bone tumor.
The outcome is usually good in 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 provider 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
Contact 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.
