You probably know the familiar burn that climbs up your chest after a heavy meal. For most of us it is just reflux, soothed with an antacid or a glass of water. For a smaller number of people, something quieter is going on underneath.
The outlook for esophageal cancer changes dramatically depending on when it is found. About half of patients live at least five years when the cancer is still contained in the esophagus, according to the American Cancer Society.
Once the cancer has spread to distant parts of the body, only about 5 in 100 reach that mark. Overall, about 22 in 100 survive five years, because most cases are caught late.
The gap matters because the earliest signs look almost identical to acid reflux. Heartburn, indigestion, a little trouble swallowing. People live with them for months or years, often blaming spicy food or stress.

The eight warning signs the NCI and ACS flag
The National Cancer Institute and the American Cancer Society list the following as the main signs to watch for.
- Trouble swallowing, often with a sense that food is sticking in the throat or chest
- Persistent heartburn or indigestion
- Chest pain or pressure behind the breastbone
- Unexplained weight loss
- Hoarseness
- Chronic cough
- Food or liquid coming back up, or vomiting after eating
- Blood in vomit, or black and tarry stools
Difficulty swallowing is the most common early complaint. It tends to start mildly, with solid foods like bread or meat, and then worsens over time as the tumor narrows the food pipe.
Many people respond by chewing longer, drinking more water with meals, or quietly switching to softer foods without mentioning it to a doctor.
When heartburn is no longer just heartburn
Ordinary reflux is common and usually not a sign of anything serious. Worth a closer look is heartburn that keeps getting worse, that antacids no longer calm, or that comes with new trouble swallowing solid food.

Weight loss you cannot explain is another red flag, especially when it lands on top of chronic reflux. The same goes for food that comes back up, or a cough and hoarseness that linger for weeks without a cold.
Most esophageal cancers do not cause symptoms until they have reached an advanced stage, the American Cancer Society notes. That is why mild but persistent warning signs deserve attention rather than another trip to the antacid aisle.
Why early recognition matters more here than for many cancers
There is no routine esophageal cancer screening for people at average risk in the United States. According to the American Cancer Society, no professional organization recommends screening for people who are not at increased risk.
No test has been shown to lower the risk of dying from the disease in that group.

People with Barrett's esophagus, a change in the lining of the food pipe caused by long-term reflux, are an exception. Experts often recommend regular upper endoscopies for them, and for some people with inherited syndromes.
For everyone else, symptom awareness is the main early-detection tool. That makes the list above matter more than it does for cancers with a standard screening program.
When to talk to your doctor
The National Cancer Institute advises checking with a doctor for any of the symptoms listed above. The American Cancer Society adds that symptoms which do not go away, or which get worse, should be evaluated so that the cause can be found and treated.
In practice that means a conversation with a primary care doctor or a gastroenterologist, who may recommend an upper endoscopy. The procedure uses a thin, flexible camera to look at the lining of the esophagus and take small tissue samples if anything looks unusual.

For anyone with heartburn that has changed, worsened or outlasted the usual home remedies, the next step is not another antacid. It is a call to the doctor's office.
