Colorectal cancer is one of the deadliest forms of the disease — but not all signs are immediately apparent.
People with early-stage colorectal cancer may not have any symptoms at all and are therefore at risk of spreading.

However, there are some changes in your body to be aware of, including strange growling sounds in your stomach.
The Sun’s ‘No Time 2 Lose’ campaign, launched in 2018 alongside Dame Deborah James, is raising awareness of symptoms and encouraging more Brits to get screened for the disease.
What are the symptoms of colon cancer?
The main signs of colon cancer are changes in your stool, such as it becoming softer, or you have diarrhea or constipation that are unusual for you.
The disease can also make you need to go to the bathroom more often, cause bleeding from your buttocks, or blood in your stools.
You may also feel the need to poop, even if you’ve just been there.
Other symptoms include abdominal pain, bloating, unwanted weight loss and a feeling of extreme tiredness for no reason.
What are stomach murmurs in colon cancer?
Colon cancer can cause stomach murmurs as gases and other substances travel through your digestive tract.
Changes inside your gut can cause a gurgling sound as food passes through.
How do stomach murmurs in colorectal cancer differ from normal stomach murmurs?
Stomach sounds can have various causes and are not always an indication of colon cancer.
These include celiac disease, irritable bowel syndrome, lactose intolerance and other food allergies.
The stomach can also growl when you are hungry, because the noises are louder when the stomach and intestines are empty.
It is not possible to determine what is causing the noise just by hearing.
When should I see a doctor about possible stomach murmurs with colon cancer?
You should see your doctor if you experience symptoms other than stomach rumblings.
If your stomach has pain and it doesn’t go away, it may be worth getting checked out.
Blood in the stool or changes in bowel movements are other signs that you should contact your doctor.
