Salivary gland cancer

Salivary gland cancer is a heterogenous group of tumors in terms of histopathology. Different types of adenocarcinomas are the main group, and malignant tumors originate most often from the parotid gland. 

The salivary glands include the:

  1. parotid gland
  2. submandibular gland
  3. sublingual gland

The salivary glands also include numerous small glands in the oral cavity and nasal mucosa.

Treatment for salivary gland cancer and the patient's sequelae of the treatment will have great consequences for the patient's appearance. The extent of the changes depends on the localization and stage of the tumor. In order to reduce the burdens the treatment can cause, thorough information and follow-up is critical (2).

Incidence

Salivary gland cancers are not very common and  represents less than 1% of all new cancer cases in the United States.

These cancers can occur in people of almost any age, but they become more common as people get older. The average age at the time of diagnosis is 64.
