Possible symptoms of collar bone cancer include bone pain, broken bones, urinary or bowl incontinence, and weakness in the legs or arms, according to Mayo Clinic. Not all patients of cancer that spreads to the bones experience symptoms.
Nausea, vomiting, confusion and constipation are experienced if the patient has high levels of calcium in their blood, also called hypercalcemia, notes Mayo Clinic.
Collar bone cancer is actually caused by cancer in another part of the body that spreads to the bone; this is called metastatic bone disease, or MBD, says OrthoInfo. The cancer begins in the lungs or breast, then spreads to nearby bones, including the collar bone. The treatment options for MBD depend on the area of the body it is affecting, including how many bones have the cancer.
Collar bone cancer is included in the upper extremity location, which also includes the breast bone, shoulders, forearms and upper arms, according to the American Academy of Orthopaedic Surgeons. Cancer in these bones often leads to impairment of the extremity's function and affects personal hygiene due to lack of movement in the arms, neck and shoulders. About 20 percent of the bone metastatic cases occur in the upper extremity of the body.
Treatment options include medications, radiation, functional bracing, surgical stabilization and reconstruction.
