• Bone and Soft Tissue Cancers (Sarcomas)

  Soft Tissue Sarcoma: Introduction

  Sarcoma is a type of cancer that starts in the body's connective tissues. These are tissues like bones and muscles that support or protect other parts of the body. Soft tissue sarcomas can start in muscles, tendons, blood vessels, fat, nerves, and deep skin tissues.

• Bone Biopsy

  Bone Biopsy

  A bone biopsy is a procedure in which bone samples are removed (with a special biopsy needle or during surgery) to find out if cancer or other abnormal cells are present. A bone biopsy involves the outer layers of bone, unlike a bone marrow biopsy, which involves the innermost part of the bone.

• Cervical Spine

  Cervical Spondylosis

  Cervical spondylosis is a type of degenerative disease that affects your neck. Normally, soft disks between the bones in your spine (called vertebrae) provide cushioning. With cervical spondylosis, these disks become squeezed (compressed).

• Chondrosarcomas

  Chondrosarcoma

  Chondrosarcoma is a malignant type of bone cancer that primarily affects the cartilage cells of the femur, arm, pelvis, knee, and spine. Chondrosarcoma is the second most common type of primary bone cancer.

• Chordomas

  Skull Base Chordoma

  A chordoma is a form of bone cancer that can occur anywhere along the length of the spine, from the base of the skull to the lower back. When it occurs at the base of the skull, it is known as skull base chordoma. Because of its location in the base of the skull, it commonly affects vital structures.

• Muscle Biopsy

  Muscle Biopsy

  A muscle biopsy is a procedure used to diagnose diseases involving muscle tissue. Your healthcare provider will remove tissue and cells from a specific muscle and view them microscopically. Your provider will only need to remove a small piece of tissue from the designated muscle.

• Oncology

  Cancer Overview

  Cancer cells don't function properly, and they can spread to many areas of the body. Tumors are clusters of cells that are capable of growing and dividing uncontrollably; their growth is not regulated.

• Osteomyelitis

  Osteomyelitis

  Osteomyelitis is an inflammation or swelling of bone tissue. It’s most often caused by an infection. Bone infection may occur for many reasons and can affect children or adults.

• Paget's Disease

  Paget Disease of the Bone

  Paget disease of the bone is a chronic bone disorder. It causes bones to become enlarged and deformed. Bone may become dense, but fragile, because of excessive breakdown and deformation of bone. The disease is the most common bone disorder after osteoporosis in people older than age 50.

• Sarcoma

  Soft Tissue Sarcoma: Stages

  Soft tissue sarcomas are usually staged with the TNM staging system from the American Joint Committee of Cancer (AJCC). Be sure to ask your healthcare provider to explain the stage of your cancer to you in a way you can understand.

• Spinal Tumor

  Spinal Cord Tumor Overview

  Spinal cord tumors are fairly uncommon. It's much more common to develop a brain tumor than a tumor on the spinal cord. A spinal cord tumor may form inside the spinal cord itself or around the bones that make up the spine.
