Salivary Gland Cancer

Overview
Overview

Salivary gland cancer is a rare disease in which malignant (cancer) cells develop in the tissue of the salivary gland. Exposure to certain types of radiation increases the risk of developing salivary cancer. The salivary glands produce saliva and release it into the mouth. Saliva contains enzymes that help in digesting foods and antibodies. Antibodies protect the mouth and throat from infections.

The most common signs and symptoms of salivary cancer include a lump or trouble swallowing. Tests that examine the head, neck and the inside of the mouth are used to diagnose the disease.  Several factors affect the treatment options and prognosis (chance of recovery).

Surgery is the main treatment option for benign salivary gland tumours. After surgery, the recovery focuses on preventing infection and managing pain. The doctor may prescribe drugs like antibiotics and pain medications to achieve the goal. For malignant salivary gland cancers, the doctor uses surgical procedures to remove the tumour. After surgery, the patient may require radiation therapy to the affected area by cancer and the draining lymph nodes. 

Radiation kills all the cancer cells so cancer doesn’t return. When cancer spreads from the salivary glands to other tissues outside the head and neck, the doctor recommends chemotherapy.
