Oral cavity cancer, a type of head and neck cancer, originates in the mouth and can affect various structures within the oral cavity. The oral cavity includes the lips, tongue, cheeks, floor of the mouth, hard and soft palates, and the pharynx (throat). This malignancy often develops from the cells lining the surfaces of these structures. The leading risk factors for oral cavity cancer encompass tobacco use, both smoking and smokeless forms, as well as excessive alcohol consumption. Additionally, infection with human papillomavirus (HPV) has been identified as a contributing factor in some cases. Early stages of oral cavity cancer may exhibit subtle symptoms, such as persistent mouth sores, difficulty swallowing or chewing, and changes in voice. As the disease progresses, more noticeable signs like persistent pain, swelling, or lumps may manifest. Diagnosis typically involves a thorough examination of the oral cavity, imaging tests, and, if necessary, a biopsy to confirm the presence of cancerous cells. Treatment options depend on factors such as the stage of the cancer, its location, and the individual's overall health. Common approaches include surgery, radiation therapy, and chemotherapy, often used in combination. Prevention plays a crucial role, emphasizing the importance of avoiding tobacco products, moderating alcohol consumption, and practicing good oral hygiene. Regular dental check-ups are essential for early detection and intervention. Overall, oral cavity cancer underscores the significance of adopting a healthy lifestyle and seeking prompt medical attention for any persistent oral symptoms. Timely diagnosis and appropriate treatment are key factors in improving outcomes and enhancing the quality of life for individuals affected by this form of cancer.
