Esophageal cancer occurs while cancer cells
develop in the esophagus, a tube-like structure that runs from your throat to
your stomach. Food goes from the mouth to the stomach as the esophagus. The
cancer begins at the inner layer of the esophagus as well as may spread
throughout the other layers of the esophagus and to other parts of the body
(metastasis).
There
are two common types of esophageal cancer:
Squamous cell carcinoma arises while cancer
starts in the flat, thin cells that make up the lining of the esophagus. This
form most often shows in the top or middle of the esophagus, however it may
appear anywhere.
Adenocarcinoma occurs while cancer begins
in the glandular cells of the esophagus that are responsible for the production
of fluids such as mucus. Adenocarcinomas are most ordinary in the lower portion
of the esophagus.
Symptoms of
Esophageal Cancer include
·
Difficulty swallowing
(dysphagia)
·
Weight loss without trying
·
Chest pain, burning or pressure
·
Worsening indigestion or
heartburn
·
Coughing or hoarseness
Although these symptoms may specify esophageal cancer,
they also can be caused by other, less serious health problems. Some esophageal
cancer patients experience none of these signs as well as others experience diverse
symptoms entirely.
Typically, the first symptom of esophageal
cancer is difficulty swallowing, which might feel as if food is stuck in the
throat as well as may lead to choking. Although this symptom is frequently mild
to start, as cancer grows, it creates worsens as well as may eventually lead to
an inability to swallow liquid.
Complications
There are a number of complications that might
occur with esophageal cancer. Some of these occur due to local contribution,
such as the narrowing of and erosion of the esophagus. Others may occur due to
the spread of the tumor as well as yet others have to do with the difficulty obtaining
sufficient nutrition with a narrowed esophagus.
Malnutrition
An extremely ordinary complication of
esophageal cancer is malnutrition due to the decreased capability to eat and
swallow foods. This may require a feeding tube, placed either through the nose
or stomach, to offer nutrition.
Hemorrhage
(Bleeding)
Some bleeding may also arise due to
ulceration of the esophagus, or as a complication of stent placement. Options
will depend on the circumstances but may include cautery (burning the bleeding
blood vessels).
Back
Pain
Back pain is fairly ordinary in advanced esophageal cancer due to the
invasion of the tumor into the area between the lungs (the mediastinum) or
between the membranes that line the heart (the pericardium).
