Symptoms

Stomach cancer is a cancer that's found anywhere in the stomach. It's very common in the UK.

There are many possible symptoms of stomach cancer.

Some are more obvious, such as:

  • losing weight without trying to
  • feeling or being sick
  • having problems swallowing (dysphagia)
  • a lump at the top of your tummy

Others might be harder to spot, such as:

  • heartburn or acid reflux
  • loss of appetite
  • symptoms of indigestion, such as burping a lot
  • feeling full very quickly when eating
  • pain at the top of your tummy
  • feeling tired or having no energy

If you have another condition, such as gastro-oesophageal reflux disease, you may get symptoms like these regularly.

You might find you get used to them. But it's important to be checked by a GP if your symptoms change, get worse, or do not feel normal for you.

Important

These symptoms are very common and can be caused by many different conditions. Having them does not definitely mean you have stomach cancer.

But it's important to get them checked by a GP. This is because if they're caused by cancer, finding it early makes it more treatable.

See a GP if you have:

  • any of these symptoms that get worse or do not get better after 3 weeks
  • a condition that causes symptoms like these, and your symptoms are not getting better after 3 weeks of using your usual treatments
  • problems swallowing
  • a lump in your tummy

What happens at the GP appointment

The GP may feel your tummy.

They may ask you to give a poo or pee sample, or have a blood test.

The GP may refer you to see a specialist in hospital for more tests if they think you have a condition that needs to be investigated.

This may be an urgent referral, usually within 2 weeks, if you have certain symptoms. This does not definitely mean you have cancer.

Cancer Research UK has more information and advice about seeing a GP sbout symptoms of stomach cancer.

Who can get it

Anyone can get stomach cancer.

It's not always clear what causes it, but you might be more likely to get stomach cancer if you:

  • are over the age of 50
  • are a man
  • have a long-term infection with Helicobacter pylori (H. pylori)
  • have certain stomach conditions, such as long-term, severe acid reflux, gastritis or a condtion called pernicious anaemia, which effects your immune system
  • have a brother, sister or parent who had stomach cancer

Stomach cancer can also be linked to your lifestyle. You may be more likely to get it if you:

  • smoke
  • are very overweight
  • work in a job where you're exposed to certain chemicals, such as in the rubber industry or coal mining
  • have too much salt in your diet
  • drink too much alcohol
  • do not eat enough fruit and vegetables
  • eat a lot of processed meat (such as ham, bacon and salami)

You cannot always prevent stomach cancer. But because many stomach cancers are linked to lifestyle, making healthy changes can lower your chances of getting it.

It is important to get any symptoms of stomach cancer checked by a GP.

Even if you do not think you fit into any of the groups with a higher chance of getting it. Anyone can get stomach cancer.

Diagnosis

Camera test

A GP or specialist will probably refer you for a test to look inside your stomach.

This test is called a gastroscopy (a type of endoscopy). It looks for any problems in your stomach, including stomach cancer.

During a gastroscopy:

  1. A long, thin, flexible tube with a small camera inside (called an endoscope) will be put into your mouth, down your throat and into your stomach.
  2. A specialist will use the camera in the endoscope to look for any problems.
  3. A small sample of cells (called a biopsy) may be collected during the procedure. These cells will be sent to a laboratory to check for cancer.

The test should take around 10 to 15 minutes.

It should not be painful, but you might find it uncomfortable.

You may be offered things to make you more comfortable and make the test easier, such as:

  • sedation - medicine given through a small tube in your arm to help you relax
  • putting you to sleep (general anaesthetic)

Cancer Research UK has more information on having an endoscopy.

Many of the symptoms of stomach cancer can also be caused by other cancers in the area, such as cancer of the food pipe (oesophageal cancer) or pancreas (pancreatic cancer).

During a gastroscopy, the specialist will look for problems in your oesophagus, stomach, and the first part of the bowels (small intestine).

Getting your results

You should get the results of a gastroscopy and biopsy within 2 weeks.

A specialist will explain what the results mean and what will happen next.

If you're told you have stomach cancer

Being told you have stomach cancer can feel overwhelming. You may be feeling anxious about what will happen next.

A group of specialists will look after you throughout your diagnosis, treatment and recovery.

Your team will include a clinical nurse specialist who will be your main point of contact during and after treatment.

You can ask them any questions you have.

Advanced stomach cancer

If you are diagnosed with advanced stomach cancer, you will probably feel a huge range of emotions.

There is lots of support available for you and your loved ones.

Your clinical nurse specialist and the rest of your specialist team can recommend both local and national support services.

Important

Macmillan Cancer Support has a free helpline that's open every day from 8am to 8pm.

They're there to listen if you have anything you want to talk about.

Call: 0808 808 00 00

Other tests

Once you have been diagnosed with stomach cancer, you will need more tests. These will help the specialists find out the size of the cancer and how far it's spread (called the stage).

You may need:

  • an ultrasound scan inside your stomach using an endoscope, called an endoscopic ultrasound
  • a CT scan
  • a PET-CT scan
  • a small operation to look inside your stomach, called a laparoscopy

The specialists will use the results of these tests and work with you to decide on the best treatment plan for you.

Macmillan Cancer Support has information on tests after you have been diagnosed and what to expect.
