Head and neck cancer is a group of cancers which begins inside the mouth, throat, nose, larynx, sinuses, or adrenal glands. Symptoms may include a lump or sore that doesn't cure, a sore throat that doesn't go away, trouble swallowing, or even a shift in the voice. There can also be unusual bleeding, facial swelling, or difficulty breathing.

Approximately 75 percent of head and neck cancer is a result of the usage of tobacco or alcohol. Other risk factors include betel quid, particular kinds of human papillomavirus, radiation exposure, particular workplace ailments, and premature virus. The level of spread might be set by clinical imaging and blood tests.
Not using alcohol or tobacco can decrease the risk. While viewing in the general populace doesn't look useful, screening high risk groups by assessment of the throat may be helpful. Many times, head and neck cancer is treatable when found early; however, outcomes are usually bad if detected late. Treatment may include a combination of surgery, radiation treatment, chemotherapy, and targeted treatment. Following treatment of a single mind and neck cancer individuals are at greater chance of another cancer.

Signs and symptoms

Throat cancer usually begins with symptoms which look harmless enough, such as a enlarged lymph node on the exterior of the throat, a sore throat or a hoarse sounding voice. Nonetheless, in the event of throat cancer, such illnesses may persist and become chronic. There might be a bulge or a sore in the throat or throat that doesn't heal or move away. There could be painful or difficult swallowing. Discussing may become hard. Other possible but less common symptoms include several numbness or paralysis of their face muscles.
Presenting symptoms include :

Mass in the neck
Neck pain
Bleeding from the mouth
Sinus congestion, especially with nasopharyngeal carcinoma
Bad breath
Sore tongue
Painless ulcer or sores in the mouth that do not heal
White, red or dark patches in the mouth that will not go away
Earache
Unusual bleeding or numbness in the mouth
Lump in the lip, mouth or gums
Enlarged lymph glands in the neck
Slurring of speech (if the cancer is affecting the tongue)
Hoarse voice which persists for more than six weeks
Sore throat which persists for more than six weeks
Difficulty swallowing food
Change in diet or weight loss
Mouth

Squamous cell cancers are common in the mouth, including the inner lip, tongue, floor of mouth, gingivae, and hard palate. Cancers of the mouth are strongly associated with tobacco use, especially use of chewing tobacco or "dip", as well as heavy alcohol use. Cancers of this region, particularly the tongue, are more frequently treated with surgerythan are other head and neck cancers.

Surgeries for oral cancers include

Maxillectomy (can be done with or without orbital exenteration)
Mandibulectomy (removal of the mandible or lower jaw or part of it)
Glossectomy (tongue removal, can be total, hemi or partial)
Radical neck dissection
Mohs procedure
Combinational e.g., glossectomy and laryngectomy done together.
The defect is typically covered/improved by using another part of the body and/or skin grafts and/or wearing a prosthesis.

Prevention

Avoidance of recognized risk factors (as explained previously) is the one most effective form of avoidance. Routine dental assessments can identify pre-cancerous lesions in the oral cavity.

When diagnosed early, oral, head and neck cancers can be treated more easily and also the odds of survival increase tremendously. As of 2017 it wasn't known if present HPV vaccines might help prevent neck and head cancer.
