C00-C14: Malignant neoplasms of lip, oral cavity and pharynx
C04: Malignant neoplasm of floor of mouth
Malignant neoplasm of the floor of the mouth is a type of oral cancer that begins in the flat cells, called squamous cells, which form the base of the mouth. It typically forms as a persistent sore or growth in the mouth. Over time, this uncontrolled cell growth can spread into the bone of the jaw or further into the body, affecting various systems. This condition may be caused by factors such as tobacco and alcohol use, exposure to certain types of human papillomavirus (HPV), or excessive sun exposure. Symptoms often include pain or difficulty swallowing, a persistent sore that doesn't heal, unexplained weight loss, and a change in voice. If left untreated, malignant oral neoplasms can progress to a more severe stage, potentially leading to serious complications or even death.
