C00-C14: Malignant neoplasms of lip, oral cavity and pharynx

C08: Malignant neoplasm of other and unspecified major salivary glands

Malignant neoplasms of other and unspecified major salivary glands is a group of conditions represented by the occurrence of cancerous tumors in the salivary glands, excluding the parotid glands. These glands produce saliva, which aids in digestion and keeps the mouth moist. Tumors can develop in any of these glands and, if malignant, can spread to other parts of the body. The exact cause is unknown, but factors such as age, exposure to radiation, and certain viral infections may increase risk. Symptoms include a lump or swelling near the jaw or neck, fluid draining from the ear, difficulty swallowing, and numbness or weakness in parts of the face. As the disease progresses, it may affect the ability to speak, chew, or swallow. Regular oral health check-ups can help in early detection of these conditions.
