What is the most common source of metastasis to the jaw in females and males?

• A. Breast; Prostate
• B. Ovary; Lung
• C. Breast; Lung
• D. Thyroid; Kidney

Answer: (C)

The most common source of metastasis to the jaw in females is indeed breast cancer, while in males, lung cancer is the most prevalent source. Breast cancer frequently metastasizes to the jaw due to the rich blood supply and the unique vascularity of the jawbone, which allows for the dissemination of malignant cells. Osteoclast activation occurs as a result of metastatic lesions, which leads to osteolytic destruction, particularly in the mandible. The close anatomical relationship of the breast to the craniofacial region, along with the higher incidence of breast cancer in women, reinforces the prominence of breast as a primary cancer source in female jaw metastasis. In males, lung cancer is a leading cause due to the high incidence of lung carcinoma and its aggressive nature, allowing for early dissemination to the skeletal system, including the jaws. Metastatic lung cancer can lead to lesions in the jaw, resulting in pain, swelling, tooth mobility, or other dental issues. This understanding aligns with clinical observations and histopathological studies, where breast and lung cancers are consistently identified as the most frequent primary malignancies that metastasize to the jaws.
