C41.0: Malignant neoplasm: Bones of skull and face

Malignant neoplasm of the bones of the skull and face refers to a cancerous tumor that develops in the bone structure of the head, either in the skull or facial bones. Unlike benign tumors, malignant neoplasms can grow aggressively, invade surrounding tissues, and spread (metastasize) to other parts of the body. Symptoms can vary depending on the location and size of the tumor and may include pain, swelling, or a noticeable lump. The tumor can potentially disrupt the function of the affected bone or area, leading to issues such as vision problems or difficulty chewing or swallowing if the facial bones are affected. Over time, without treatment, the tumor can grow and cause more severe symptoms, potentially affecting overall health and well-being. Despite having various potential causes, this condition is often associated with long-term exposure to radiation, certain inherited syndromes, or previous treatments for other cancers.
