Head and Neck Cancers
Head and neck cancer refers to the cancer that originates from the head and the neck. It involves cancers of the mouth, lip, sinuses, nasal cavity, pharynx and larynx. Usually head and neck cancer arises from the mucosal lining, the moist tissues that line in the throat, nose and mouth.
Risk factors and causes
There are a wide variety of factors that may cause head and neck cancer, although environmental and lifestyle risk factors are usually linked with head and neck cancer. Common risk factors and causes include smoking (particularly tobacco smoking), alcohol drinking, excessive sun exposure (ultraviolet rays) and occupational exposure.
Common symptoms include neck pain, neck mass, difficulty when swallowing, change in voice, sore throat or a lump does not heal, weight loss, halitosis, unusual bleeding from the mouth and ear ache.
Head and Neck Cancers Treatment and Prevention
The treatment may vary depending on the type of cancer. Common treatments include surgery, chemotherapy, photodynamic therapy, radiation therapy, targeted therapy or a combination.
Avoiding risk factors (heavy use of alcohol and tobacco) may prevent head and neck cancer. A regular visit to an ENT specialist will help diagnose early signs of cancer and may prevent further progression of the disease.
