    Which one of the following is a characteristic of benign tumors?

    • Numerous mitotic figures

    • Rapid growth

    • Slow growth

    • Metastasis

    Correct Answer
    A. Slow growth
    Explanation
    Benign tumors are characterized by slow growth. Unlike malignant tumors, which grow rapidly, benign tumors tend to grow at a slower pace. This is because benign tumors do not invade surrounding tissues or spread to other parts of the body (metastasis). While they may still cause health issues depending on their location and size, the slow growth of benign tumors is a key characteristic that distinguishes them from malignant tumors.

    Which one of the following malignant tumors has been reported to ashow a characteristic "sunburst" pattern on readiographic examination

    • Malignant melanoma

    • Osteosarcoma

    • Squamous cell carcinoma

    • Rhabdomyosarcoma

    Correct Answer
    A. Osteosarcoma
    Explanation
    Osteosarcoma is the correct answer because it is a malignant bone tumor that can exhibit a characteristic "sunburst" pattern on radiographic examination. This pattern is caused by the aggressive growth of the tumor, which leads to the formation of spicules of bone radiating outwards from the central tumor mass. This appearance is often seen in X-rays and is a distinguishing feature of osteosarcoma. Malignant melanoma, squamous cell carcinoma, and rhabdomyosarcoma are not typically associated with this specific radiographic pattern.
