Overview

Hepatitis A
Hepatitis A is an infection of the liver caused by the hepatitis A virus. It is usually spread when a person ingests food or water contaminated with infected stool, or through close contact with an infected person. Symptoms can include tiredness, nausea, abdominal discomfort, dark urine, loss of appetite, and jaundice. Most people recover fully.
Esophageal Cancer
Esophageal cancer is a malignant tumor that develops in the esophagus, the muscular tube that carries food from the throat to the stomach. Early disease may cause few or no symptoms. As the tumor grows, people may develop difficulty swallowing, painful swallowing, weight loss, chest discomfort, or persistent indigestion.

Diagnosis

Hepatitis A
Hepatitis A is diagnosed using the symptoms, medical history, physical examination, and blood tests. Testing can identify antibodies associated with recent hepatitis A infection, while liver-function tests may show inflammation or impaired liver function. The clinician may also assess exposure history, travel, food or water exposure, and other possible causes of hepatitis.
Esophageal Cancer
Diagnosis usually begins with evaluation of swallowing difficulty, chest or upper abdominal symptoms, weight loss, and other concerning findings. Upper endoscopy allows direct examination of the esophagus and collection of tissue for biopsy. CT, PET, or other imaging may then be used to assess the tumor, nearby structures, lymph nodes, and possible spread.

Prevention

Hepatitis A
Hepatitis A can often be prevented through vaccination, careful handwashing, safe food handling, and drinking safe water. Wash hands thoroughly after using the toilet and before preparing or eating food. Avoid contaminated food and water when traveling in areas where hepatitis A is common. People exposed to the virus who are not immune should promptly discuss vaccination or preventive treatment with a healthcare professional.
Esophageal Cancer
Avoiding tobacco, limiting alcohol, maintaining a healthy weight, and managing chronic acid reflux can help reduce several risk factors associated with esophageal cancer. People with Barrett esophagus should follow recommended medical surveillance and treatment. Persistent or progressive difficulty swallowing, unexplained weight loss, or other concerning symptoms should be medically evaluated.

Risk Factors

Hepatitis A
Risk of hepatitis A is higher with travel or residence in areas where the infection is more common, close contact with an infected person, poor sanitation, unsafe food or water, and certain sexual practices. People who use injection drugs and those working in settings involving food, healthcare, childcare, or sewage may also have increased exposure.
Esophageal Cancer
Risk factors include cigarette smoking, heavy alcohol use, chronic gastroesophageal reflux disease, Barrett esophagus, obesity, certain dietary patterns, and increasing age. Some inherited conditions, environmental exposures, and previous abnormalities of the esophagus may also increase risk. Risk varies according to the type of esophageal cancer.
