C00-C14: Malignant neoplasms of lip, oral cavity and pharynx
C06: Malignant neoplasm of other and unspecified parts of mouth
"Malignant neoplasm of other and unspecified parts of mouth" refers to a group of cancers that develop in various sections of the mouth not specifically categorized elsewhere. This type of malignancy can be linked to multiple risk factors, one of which is frequent tobacco and alcohol use. Another well-known cause is the human papillomavirus (HPV). These cancers usually start as small, often unnoticed changes in the mouth's soft tissues, such as a lump or a sore that doesn't heal. As the disease progresses, individuals may experience symptoms including persistent mouth pain, loose teeth, or difficulty swallowing. While these cancers primarily affect the oral cavity, they can also spread to other body systems, such as the lymphatic system, altering their normal functions.
