In a 70-year-old male, which cancer is most likely to spread to the mandible?

• A. Prostate
• B. Breast
• C. Lung
• D. Skin

Answer: (C)

Lung cancer is known for its propensity to metastasize to various sites in the body, including the bones. In elderly males, such as the 70-year-old patient in this scenario, lung cancer is one of the most common malignancies and frequently spreads to the mandible and other skeletal structures. The mandible can serve as a site for metastatic disease due to its rich blood supply and the presence of marrow. Lung cancer, particularly in its advanced stages, can lead to systemic spread and bone metastases. This is more prevalent in older adults who may have a history of smoking or other risk factors for pulmonary malignancies. While prostate cancer can also metastasize to bone, the incidence of mandible involvement is less common than with lung cancer. Similarly, breast cancer has a propensity to metastasize to bone as well, but it usually favors the spine and ribs. Skin cancers, while they can metastasize, are less likely to spread to the mandible compared to lung cancer. Thus, lung cancer emerges as the most likely primary malignancy to metastasize to the mandible in an older male patient.
