Esophageal cancer [SEP] Causes
The two main types (i.e. squamous-cell carcinoma and adenocarcinoma) have distinct sets of risk factors. Squamous-cell carcinoma is linked to lifestyle factors such as smoking and alcohol. Adenocarcinoma has been linked to effects of long-term acid reflux. Tobacco is a risk factor for both types. Both types are more common in people over 60 years of age.
