Head and Neck Cancers


Head and Neck Cancers

Cancers of Head and Neck - Lip Cancer, Tongue Cancer, Mouth Cancer or Oral Cancer, Throat Cancer or Neck Cancer, Nasopharyngeal Carcinoma, Hypopharyngeal Cancer, Laryngeal Cancer, Oropharyngeal Cancer and Thyroid Cancer 

Cancers of Head and Neck by Cell Type - Squamous Cell Carcinoma, Adenocarcinoma, Papillary Cell Carcinoma and others 

Other Rare Types of Head and Neck Cancer by Cell Type -  Basal cell carcinoma, Adenoid cystic carcinoma, Mucoepidermoid carcinoma, Anaplastic carcinoma, verrucous carcinoma, Mucoepidermoid carcinoma, Malignant mixed tumor, Follicular carcinoma, Medullary thyroid carcinoma and others. 

Cancers of Head and Neck are defined by identifying the area in which cancer cells originate. Head and Neck cancer can affect areas of our Mouth (Oral Cavity - Lips, Tongue, Gums, Cheeks, Nasal Cavity etc) and Neck (Pharynx and Larynx). Cancers types are also generally described based on particular structure they originate in such as 

Lip Cancer (Malignant cells that originate in Lip) 

Tongue Cancer (Malignant cells that originate in Tongue) 

Nasopharyngeal Carcinoma (Malignant cells that originate in Nasopharynx) 

Hypopharyngeal Cancer (Malignant cells that originate in Hypopharynx) 

Laryngeal Cancer (Malignant cells that originate in Larynx) 

Oropharyngeal Cancer (Malignant cells that originate in Oropharnx) 

Thyroid Cancer (Malignant cells that originate in Thyroid gland) 

Lymphomas (Malignant cells that originate in the Lymph nodes of Head and Neck) 

Mouth Cancer or Oral Cancer 

Cancer cells which begin in Oral Cavity are most commonly known as Mouth Cancer or Oral Cancer. Cancer cells of oral cavity can originate in lips, tongue, gums, cheeks, both upper and bottom floor of the mouth and small area behind wisdom teeth. They can also originate in salivary glands, under the jaw bone, sinuses and nasal cavity. When a doctor identifies these abnormal malignant cells in any of the areas of oral cavity the doctor will inform that the indivdual is diagnosed with Mouth Cancer or Oral Cancer. 

However the histological diagnosis of Mouth Cancer or Oral Cancers are reported as either Squamous Cell Carcinoma or Adenocarcinoma depending on which type of cells they originate from. If the malignant cells originate in particular type of cells known as sqamous epthellium(cells that line various structurs of oral cavity) the cancer will be diagnosed by a pathologist in the histopathology report as squamous cell carcinoma. 

This preliminary diagnosis is very important as the subsequent treatment an oncologist will plan will be based on the histological diagnosis (microscopic examination of tissue by a pathologist) of the cancer type and its origins. It is beneficial to get a second opinion of your biopsy test from a comprehensive cancer centre. 

Throat Cancer or Neck Cancer 

Cancer cells which begin in areas of your throat or neck are generally known and described as Throat Cancer or Neck Cancer. Cancer cells in throat or neck originate in structures of Pharynx (a tube that starts behind nose and leads to esophagus and trachea), Nasopharynx (parts behind the nose), Oropharynx (back part of the mouth, base of tongue and tonsils) or Larynx (voicebox, vocal cords and epiglottis) are all commonly known as throat cancer or neck cancer.
