What is oesophageal cancer?
Oesophageal cancer is caused when the lining of the oesophagus experiences abnormal cell growth. There are two types of abnormal cell growth:
Squamous cell cancer
The lining of a healthy oesophagus consists of squamous or flat cells similar to the cells in the skin. Abnormal growth in these cells causes a squamous cell cancer that can affect the oesophagus along its entire length.
Persistent acid-reflux can cause cells in the oesophageal lining to experience negative change and start resembling cells in the stomach lining. This transformed oesophagus is known as Barrett’s Oesophagus and is highly at risk of developing cancerous growths, leading to a cancer called an adeno-carcinoma.
