One of the most common types of cancer around the world is head and neck cancer. According to a study published in the Indian Journal of Cancer, around 30% to 40% of all cancers in India are in the head and neck region . Smoking and chewing tobacco are the major causes of such cancers. Head and neck cancer covers abnormal growth of cells in the mouth, throat, voice box, nose, and salivary glands.
These cancers generally take place in the squamous cells in the soft surfaces of the head and neck. Squamous cell carcinoma (SCC) constitutes over 90% of all head and neck cancer.

Types of head and neck cancer?
Different types of Head and neck cancers are as follows.
- Oral cancer: Cancer that develops on your tongue, mouth, lips, and gums, inside your mouth, the backside of your wisdom teeth, etc.
- Oropharyngeal cancer: There are multiple types of oropharyngeal cancer, such as the oropharynx, gums, tonsils, and cancer in the floor of the mouth. Tonsil cancer is the most common type of oropharyngeal cancer
- Hypopharyngeal cancer: Cancer that grows in the lower part of your throat
- Laryngeal cancer: Cancer that develops on your vocal cord or voice box
- Nasopharyngeal cancer: Cancer that surrounds the upper portion of your throat
- Salivary gland cancer: Cancer that grows on the glands and produces spit
- Nasal cavity and paranasal sinus cancer: It grows in the nasal cavity, the hollow spaces of your nose
Head and neck cancers could sometimes attack the lymph nodes, the upper part of your neck. However, despite the similarity in locations, certain cancers, such as thyroid, eye, oesophagal, etc., require different treatment procedures.
Head and Neck Cancer Causes
Alcohol and Tobacco
The use of alcohol and tobacco including secondhand smoke are significant risk factors for head and neck cancer. People who consume alcohol and tobacco are at a greater risk of developing an oral cavity, hypopharynx, and voice box cancer.
In India, the consumption of betel quid (paan) is quite common and betel nut plays an important role in its preparation. However, they can put you at high risk of developing oral cancers.
Exposure to radiation can lead to developing cancerous cells in your salivary glands.
Ultraviolet Light Exposure
Direct exposure to ultraviolet light puts you at risk of head and neck cancer.
The cancer-causing type of human papillomavirus (HPV)  can cause oropharyngeal cancers  involving tonsils or the base of the tongue. Around 75% of all oropharyngeal cancers are a result of chronic HPV infection .
Exposure to certain types of jobs also poses a threat of head and neck cancer. For instance, people working in the construction, metal, ceramic, logging, textile, and food industries are at risk of voice box cancer. Similarly, industrial exposure to wood dust or nickel dust can cause paranasal sinuses and nasal cavities.
Epstein-Barr Virus InfectionNasopharyngeal cancer and salivary glands cancer can occur due to Epstein-Barr virus infection .
Ancestry and Genetic Disorders
Certain ancestry can be a risk factor for cancer. Genetic disorders, for instance Fanconi anemia, can also increase the chances of developing cancers early in life .
Factors that can cause head and neck cancer
Sex and age play a big role in head and neck cancers. They are usually seen among men, especially those who are AMAB or declared male at birth and have crossed fifty years of age. Other risk factors are increasing tobacco intake, too much alcohol consumption, and HPV infections.
- Tobacco consumption: Tobacco is a leading cause of cancer in the head and neck areas. Cigarette smoking, using cigars, and chewing tobacco through pipes are major contributing factors. Even a person with secondhand smoke also carries the risk.
- Excessive alcohol consumption: Consuming alcohol in huge amounts could increase your risk of head and neck cancer. According to the Centers for Disease Control and Prevention (CDC), men and AMAB should not consume more than two drinks daily.  Women and AFAB or those declared women at birth should not exceed more than one drink per day.
- Human papillomavirus (HPV): This HPV infection is caused by a human virus and is most prevalent in young adults. This virus causes a majority of oropharyngeal cancers.
- Epstein-Barr virus (EBV): Research claims that this herpes family of viruses could also contain the risk of nasopharyngeal cancer. 
- Weakening immunity: A poor immune system cannot fight off cancer cells in the body. HIV-infected persons and those with serious surgeries like organ transplants or bone marrow infections could also suffer from head and neck cancers.
- Hazardous working environment: If you are exposed to pesticides, asbestos, paint fumes, wood dust, etc., due to work-related necessities, it could increase the chance of head and neck cancers.
- Radiation exposure: If you have undergone radiation therapy in the past, it could also pose a small risk of salivary gland cancer.
- Diet: Consuming excessive amounts of meat and fish preserved with salts could also up the risk of nasopharyngeal cancer.
- Genetic reasons: Sometimes, cancer is genetically linked. A certain hereditary condition called Fanconi anaemia which results in a decreased production of blood cells also increases the risk of cancers.
- Poor dental hygiene: Poor dental hygiene sometimes could elevate the risk of oral cancer and periodontal disease.
What are the ways to diagnose head and neck cancer?
Detection at an early stage, helps in the better management of the disease. The following tests are usually performed on the patients to confirm the diagnosis:
- Physical examination: Your doctor may examine your neck, tongue, throat, and nasal cavities to check for abnormal growth or lumps.
- Endoscopy: a procedure such as nasal endoscopy is carried out with the help of a thin, lighted tube inside the areas of your nasal cavity to check for abnormalities. A laryngoscopy is another treatment that helps the doctor to see the condition of your voice box.
- Imaging tests: X-rays, CT scans, and PET scans are a few imaging tests conducted to confirm head and neck cancers. They click pictures of the affected areas and based on the images, your healthcare provider will proceed with the treatment.
- Blood tests: Some tests are also conducted to check for viruses such as HPV or EBV. The tests include some biomarkers which tell proteins commonly found in the case of head and neck cancers. These tests help the doctor to decide the course of treatment.
- Biopsy: This method refers to picking up some tissues of the affected parts and getting them checked by a pathologist. This is the most established way to diagnose cancer cells.
How head and neck cancer are treated?
Some primary and standard treatments include radiation therapy, surgery, and chemotherapy to treat head and neck cancers. Some new treatments have come, such as immunotherapy and targeted therapy to deal with cancer. Targeted therapy prescribes medicines to target some proteins that control the growth of cancer cells. At the same time, immunotherapy also involves drugs to boost the immune system and stop cancer cell growth. In some cases, clinical trials are also recommended for patients.
- Surgery: Surgery is one of the recommended procedures to deal with head and neck cancers. During surgery, the tumour is removed together with some surrounding tissues. Sometimes the lymph node is also removed if the cancer cells are found there.
- Radiation therapy: During radiation, high-energy X-rays are administered targeting the tumour. This is done as an independent treatment method or sometimes in combination with other treatments such as chemotherapy and surgery. It helps minimize the symptoms.
- Chemotherapy: This is used as a single medicine or combined with other drugs to destroy malignant cells. It is mostly used when the cancer is at an advanced stage.
- Targeted therapy: These medicines target proteins that help develop cancer cells. It is usually combined with other treatment methods.
- Immunotherapy: Immunotherapy medicines strengthen your immune system to find and destroy cancer cells.
- Clinical trials: Doctors sometimes suggest clinical trials for cancer patients. It is a research study done on people to know the safety and efficacy of certain cancer medicine. Recent research on head and neck tests, immunotherapy drugs, and various radiation methods is ongoing to give better treatment options to people suffering from this disease.
Lastly, your doctor may suggest palliative care for patients suffering from head and neck cancers. It involves a group of professionals, including doctors, nurses, and other caregivers, who help patients to deal with long-term treatments. They help you make decisions regarding your treatment and handle your routine activities. This significantly improves the quality of life of patients.
