Throat cancer, also known as pharyngeal cancer, develops in the pharynx, which is the hollow tube that connects behind the nose to the oesophagus. We classify it as nasopharyngeal, oropharyngeal, or hypopharyngeal cancer, depending on the affected area. Coming from the flat cells lining the throat, most are squamous cell carcinomas.
Important risk factors include smoking, binge drinking, HPV infection, and contact with some industrial toxins. Additionally associated with nasopharyngeal cancer are Epstein-Barr virus (EBV) infections.
Symptoms typically begin gradually and may include a persistent painful throat, difficulty swallowing, hoarseness, earache, constant coughing, unexplained weight loss, or a lump in the neck. Given these symptoms sometimes resembling prevalent diseases, identification can be delayed.
Diagnosis calls for endoscopy, biopsy, and imaging studies like CT, MRI, or PET scans. Depending on cancer location, size, and stage, treatment choices could include radiation therapy, chemotherapy, surgery, or a combination.
Improved survival rates have come from developments in immunotherapy and focused therapy. Early diagnosis greatly improves results; hence, regular visits are critical—especially for those at high risk.
