Oropharyngeal cancer is a type of head and neck cancer that affects the back of the throat, including the base of the tongue, tonsils, soft palate, and walls of the pharynx. It is often associated with risk factors such as tobacco and alcohol consumption, as well as infection with the human papillomavirus (HPV). Symptoms of oropharyngeal cancer may include a sore throat, difficulty swallowing, ear pain, a lump in the neck, or changes in voice. Diagnostic tests may include physical exams, imaging tests, and biopsies. Treatment for oropharyngeal cancer may involve surgery, radiation therapy, chemotherapy, or a combination of these modalities. Prognosis for patients with oropharyngeal cancer can vary depending on factors such as the stage of the cancer, overall health of the patient, and response to treatment. Early detection and treatment can improve outcomes for individuals with oropharyngeal cancer.
