Overview

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.
Atrial Fibrillation
Atrial fibrillation is an irregular and often rapid heart rhythm caused by disorganized electrical activity in the upper chambers of the heart. The irregular rhythm can reduce efficient heart function and increase the risk of blood clots and stroke. It may occur with heart or other medical conditions, although sometimes no specific cause is identified.

Diagnosis

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.
Atrial Fibrillation
Atrial fibrillation is diagnosed by evaluating the heart rhythm and medical history. An electrocardiogram (ECG) can record the irregular rhythm and is commonly used for diagnosis. If episodes are intermittent, Holter monitoring or another ambulatory heart monitor may be used. Echocardiography can assess heart structure and function, while blood tests may help identify contributing conditions such as thyroid disorders.

Prevention

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.
Atrial Fibrillation
Maintaining cardiovascular health may help reduce the risk of atrial fibrillation and its complications. Control blood pressure, diabetes, and other cardiovascular conditions through appropriate medical care. Maintain a healthy weight, remain physically active, avoid smoking, and limit excessive alcohol use. Sleep disorders and thyroid conditions should also be appropriately evaluated and managed when present.

Risk Factors

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.
Atrial Fibrillation
Risk of atrial fibrillation increases with age and with conditions that affect the heart or cardiovascular system. Important risk factors include high blood pressure, coronary artery disease, heart failure, heart valve disease, obesity, diabetes, thyroid disorders, and sleep apnea. Excessive alcohol use and other factors that affect heart rhythm may also increase the likelihood of developing atrial fibrillation.
