By itself, burping a lot is not typically a sign of cancer. However, when excessive burping occurs alongside other symptoms, it could indicate certain types of cancer.

Burping, or belching, refers to the release of air from a person’s stomach through their mouth. While there is no definition for excessive burping, an individual may notice they are belching more than usual. Burping most often occurs due to someone swallowing excess air, although some health conditions can also cause it.

Excessive burping may also signify certain gastrointestinal cancers. However, burping often occurs alongside other symptoms, such as pain and swelling. Burping a lot by itself is not typically a sign of cancer.

In this article, we will discuss whether excessive belching may be a sign of cancer.

Some types of cancer may obstruct a person’s digestive tract. This can lead to the individual having excess stomach gas and burping a lot.

It is important to note that excessive burping alone is not usually a cancer symptom. It may indicate a serious condition if someone is burping a lot and has other symptoms, such as:

  • unexplained weight loss
  • fevers
  • bleeding

Other symptoms that often accompany burping but are not typically a sign of cancer may include:

  • abdominal pain
  • diarrhea
  • constipation

Burping can sometimes be a symptom of:

Burping is not always an early symptom of cancer. A person may only develop excessive burping in the later stages of the disease. For example, burping is not an early sign of stomach cancer, but it may become more noticeable for a person as the cancer advances. Most people with stomach cancer also experience fatigue as a symptom alongside excess burping.

Indigestion, in addition to burping, is one symptom of many that could indicate a person has esophageal or pancreatic cancer. One other common symptom of esophageal cancer is dysphagia, or difficulty swallowing.

A person with cancer may experience various symptoms. Early detection and treatment by healthcare professionals can improve a person’s odds of successful cancer recovery.

If a person has symptoms that do not get better after a few weeks or has warning signs of cancer, it is advisable to consult a doctor. A healthcare professional will be able to assess the symptoms, give a diagnosis, and provide suitable treatment.

There are many different warning signs and symptoms of cancer. Some general signs and symptoms may include:

  • fever
  • extreme fatigue
  • weight loss or gain for no known reason
  • bleeding
  • lumps anywhere on the body
  • skin changes
  • persistent coughing
  • headaches
  • vision problems
  • bowel problems

However, it is important to note that these are general symptoms. If a person notices these symptoms together with burping, it does not necessarily mean they have cancer.

Doctors may suspect a person has cancer according to their symptoms or screening test results. Doctors will then confirm and diagnose cancer using:

Doctors may also perform a biopsy, a procedure where a doctor removes a small piece of body tissue. A pathologist then tests the tissue for cancer. Healthcare professionals can often only be sure a person has cancer with a biopsy.

Cancer treatment options depend on the type of cancer. A doctor will advise a person with the disease which options are best for them and suitable to the type of cancer they have.

For people with pancreatic, stomach, or esophageal cancer, doctors will treat them using one or more of the following methods:

  • removing some or all the affected organs with surgery
  • destroying cancer cells with X-rays, called radiation therapy
  • stopping cancer cells growth with drugs, called chemotherapy
  • using a combination of radiation and chemotherapy, called chemoradiation therapy
  • attacking specific cancer cells with drugs in targeted therapy
  • stimulating a person’s own immune system into destroying cancer cells, called immunotherapy
  • destroying cancer cells with a targeted laser beam, called laser therapy
  • destroying cancer cells with electric current, called electrocoagulation

A person burps when they swallow excess air. This can happen if they:

  • drink or eat too fast
  • drink carbonated or caffeinated drinks
  • do not chew food completely
  • smoke
  • have nervous habits, such as excessive swallowing
  • have denture fitting issues

Other health conditions can also cause people to burp a lot. These include:

People can prevent excessive belching by avoiding:

  • carbonated or caffeinated drinks or drinks with artificial sweeteners
  • chewing gum
  • sucking on hard candy

They can also:

  • eat or drink more slowly
  • stop smoking, if applicable
  • chew food more completely
  • take regular daily exercise

People can also limit gas-producing foods to help burp less. These foods include:

  • vegetables, including beans, peas, lentils, and onions
  • leafy vegetables, such as broccoli, cabbage, and cauliflower
  • whole grains
  • fatty or spicy foods

Burping a lot is not typically a symptom of cancer, and there are potentially more likely reasons for excessive burping.

However, if a person is excessively burping and experiencing other warning symptoms, they should speak with a doctor as soon as possible. Burping, along with certain other symptoms, can be a sign of gastrointestinal cancer.

If so, early detection, diagnosis, and treatment by healthcare professionals greatly increase a person’s likelihood of recovery. If an individual suspects they may have warning signs of cancer, they should consult a doctor as soon as possible.
