What symptoms might indicate osteosarcoma?

• A. Headache and fever
• B. Pain and swelling
• C. Numbness and tingling
• D. Localized heat and redness

Answer: (B)

In the context of osteosarcoma, which is a type of bone cancer, the symptoms typically associated with this condition include pain and swelling in the affected area. Osteosarcoma often presents with localized pain that may be persistent and worsen with activity. Swelling can also occur due to the growth of the tumor within or around the bone.

These symptoms arise because as the tumor grows, it can create pressure on surrounding tissues and nerves, leading to discomfort. Additionally, swelling might be observed as the body responds to the tumor, which can cause changes in local circulation and fluid accumulation.

Other potential symptoms of osteosarcoma may include a noticeable mass, particularly in the long bones of the arms or legs, and sometimes systemic symptoms like fever or fatigue if metastasis has occurred. However, the most characteristic early signs are pain and swelling, making those the primary symptoms to observe.
