What are bone cancer symptoms and signs?
Pain is the most common symptom of bone cancer. The pain may initially develop at certain times of the day, often at night, or with physical activity. The pain tends to progress and worsen over time. Sometimes, the pain may be present for years before the affected person seeks treatment. Sometimes bone cancer is detected incidentally when X-rays or imaging studies are performed for another reason. Occasionally, a mass, swelling, or lump is felt around the area of a bone cancer. Bone fractures can also occur at the site of bone cancer because the underlying bone structure has weakened. Less commonly symptoms are caused by compression or disruption of nerves and blood vessels in the affected area. These symptoms can include numbness, tingling, tenderness, or a decrease in blood flow beyond the site of the tumor, causing a cold hand or foot with weak or absent pulses.
