Bone cancer refers to the unusual and uncontrolled growth of cells in the bone. When this occurs, it destroys normal bone tissue. It may start in the bone, and from there, metastasize or spread to other parts of the body. This type of cancer affects both children and adults. Bone cancer occurs in any bone in the body. But it is most commonly found in the long bones of the arms and legs.
Bone cancer, however, is uncommon and makes up just one percent of all kinds of cancer. Most growths in the bone are benign. However, the tumors may weaken or break bones, or cause other bone-related health issues.
Common types of benign bone tumors include:
This is the most common type of bone tumor, and usually occurs in people under 20. A giant cell tumor is usually found in the leg, and maybe cancerous in rare cases.
This tumor often grows in the long bones, and usually afflicts people in their early 20s.
This is a rare tumor that occurs mostly in young adults and grows in the spine and long bones.
This type usually appears in the bones of the hands and feet, and is the most common type of hand tumor.
There are two types of bone cancer:
- Primary. Primary bone cancer, or bone sarcoma, is a cancerous tumor.
- Secondary. This type of cancer refers to bone cancer that begins in another part of the body. Secondary cancer is actually more common than primary bone cancer, and is commonly caused by lung, breast, or prostate cancers.
The types of bone sarcoma are:
This is the most common type of bone cancer and often forms around the knee, upper arm, and pelvis. It is common among teens and young adults. This type of bone cancer involves osteoblast activity. Osteoblasts are responsible for bone formation and design.
This can be found in patients as young as 5 up to 20 years old. This type of cancer can start in the soft tissue around the bones. It is most commonly found in the ribs, pelvis, leg, and upper arm.
This type of cancer affects older people, between ages 40 and 70. This particular cancer often starts in the cartilage cells and occurs commonly in the hip, pelvis, leg, arm, and shoulder.
Malignant Fibrous Histiocytoma
This can occur in the arms and legs but often starts in the soft tissue.
This also starts in the soft tissue, but may also begin in the arms, legs, or jaw.
