Head and neck cancer refers to a group of cancers that develop in the mouth, throat, nose, sinuses, or salivary glands. These cancers can affect various areas within the head and neck region, including the oral cavity, larynx, pharynx, and nasal cavity. Risk factors for head and neck cancer include tobacco and alcohol use, as well as infection with certain strains of the human papillomavirus (HPV). Symptoms of head and neck cancer can vary depending on the specific location of the tumor, but may include persistent sore throat, difficulty swallowing, changes in voice, or a lump or mass in the neck. Treatment for head and neck cancer typically involves a combination of surgery, radiation therapy, and chemotherapy. Early detection and treatment are important for improving outcomes and quality of life for patients with head and neck cancer. Research in this area focuses on developing new treatment options, improving early detection methods, and understanding the genetic and environmental factors that contribute to the development of head and neck cancer.
