Stomach cancer symptoms, diagnosis, treatment and prognosis

Stomach cancer symptoms

Early symptoms of stomach cancer tend to be vague and not very specific, so may be mistaken for other conditions with similar symptoms.
This can delay a person seeking medical advice and getting a diagnosis. The earlier a cancer is detected, the better the chance is that treatment will be successful.

Stomach cancer symptoms include:

With advanced stomach cancer, additional symptoms may include:

Stomach cancer alarm symptoms

Because stomach cancer symptoms can be so vague, the Department of Health has issued a list of what it calls alarm symptoms for people at an increased risk of stomach cancer.

Seek medical advice as soon as possible if you have any of these alarm symptoms and signs:

  • Difficulty swallowing
  • Indigestion in combination with one or more of weight loss, being sick or anaemia.
  • Being over 55 with persistent indigestion
  • Indigestion and having a family history of stomach cancer, previous surgery for stomach ulcers, Barrett’s oesophagus, pernicious anaemia, dysplasia or gastritis.
  • Jaundice, with yellowing of the eyes and skin
  • A swollen mass in the upper abdomen

Stomach cancer diagnosis

If a person's symptoms lead a GP to suspect stomach cancer, a referral will be made to a hospital cancer specialist for tests. 

Tests may include:

  • Blood tests
  • Chest X-ray
  • Stool (poo) sample to check for blood

Imaging tests to look inside the body to look for signs of stomach cancer include:

  • Endoscopy or endoscopic ultrasound using probes on the end of tubes passed down through the throat
  • Barium meal X-ray, or barium swallow, using special liquid to make the stomach show up better on an X-ray
  • Laparoscopy with a camera on the end of a tube passed through a cut in the abdomen
  • CT or PET scan
  • If an abnormal area is found, the doctor will remove some tissue to be examined under a microscope, called a biopsy, to confirm the presence of cancer cells.

Staging and grading stomach cancer

If stomach cancer is diagnosed, the severity of the cancer will be assessed with a process called staging. This ranges from stage 1A where the cancer has not spread beyond the inner lining of the stomach, to stage 4, where it has spread to other parts of the body.

Most stomach cancers are confirmed when they have already spread beyond the stomach. This usually means a complete cure is not possible.

Stomach cancers are also graded. The grades are:

  • Low-grade, spreading slowly
  • Medium-grade, spreading slightly faster
  • High-grade, aggressive and spreading quickly
