Hip bone cancer results from the malignant growth of a tumor in the hip bone. Cancers arising in the bone, which are known as primary bone cancers, are very rare, accounting for less than 1 percent of all cancers, according to the National Cancer Institute. Doctors diagnose approximately 2,300 new cases of primary bone cancer each year in the United States.

The most common symptom of hip bone cancer is pain, which is usually localized to the site of the tumor. Patients with bone cancer often describe the pain as achy and dull, according to reports from the University of Connecticut Health Center. The pain may worsen with activity or may be unaffected by activity. The pain can be severe enough to wake patients from sleep during the night. In some cases, the tumor does not cause any pain until another injury occurs near the tumor, causing the tumor to begin hurting.
As the tumor grows and spreads through the hip, the hip bone can become weak and structurally unsound. Memorial Sloan-Kettering Cancer Center experts confirm that hip bone cancer causes an increased risk of fracture of the hip bone. A broken hip causes intense pain and severe debilitation.
Hip bone cancer can also cause more general symptoms, including fevers and nights sweats, which are periods of intense sweating that occur during sleeping hours. Cancer of the hip bone may also cause fatigue and general lack of energy. The area around the tumor may also become inflamed and swollen. In some cases, hip bone cancer can affect how people walk, causing stumbling, resulting in more falls and fracture complications.
