Overview

Head and neck cancer is a group of cancers that start in the mouth, throat, voice box, nasal cavity, sinuses, or salivary glands. Most of these cancers start in the lining of these structures and are called squamous cell carcinomas. Head and neck cancers can change how you look, speak, swallow, and breathe, depending on where they are. Adults, especially men over fifty, are more likely to get them. Finding the problem early increases the likelihood that treatment will work. It's important for people to know about symptoms and risk factors so they can be diagnosed quickly and achieve better outcomes.

Symptoms
The symptoms depend on where the problem is. Some common signs are a sore throat that won't go away, trouble swallowing, a hoarse voice, mouth ulcers that won't heal, lumps in the neck, unexplained weight loss, and ear pain that won't go away. There may also be white or red patches inside the mouth. A medical evaluation is necessary for symptoms that persist for more than 2 weeks.

Causes
Smoking in any form and drinking too much alcohol are two of the biggest risk factors. Human papillomavirus infection is a significant etiological factor in specific throat cancers. Poor oral hygiene, long periods of sun exposure for lip cancer, and exposure to some chemicals at work may also raise the risk. In some cases, family history may play a role.

Diagnosis
To make a diagnosis, doctors examine the mouth and throat, perform imaging tests such as CT or MRI, and take a biopsy of any suspicious lesions. Endoscopy can be used to look at deeper areas. More tests will find out how far the disease has spread and what stage it is in.

Treatment
The type, location, and stage of cancer all affect how it is treated. You can choose from surgery, radiation therapy, chemotherapy, targeted therapy, or a mix of these. It may be possible to treat early-stage cancers with just one method. Advanced cases frequently necessitate combined therapy. Rehabilitation, including speech and swallowing therapy, helps people improve.

The prognosis is contingent upon the stage and particular location of the cancer. Finding it early makes a big difference in survival. Not smoking and drinking less alcohol greatly lowers your risk. Regular screenings and prompt evaluation of symptoms improve treatment outcomes.
