Decembeard: Bowel Cancer Awareness Month

At London Doctors Clinic, our GP's often see patients complaining of "upset tummies" or "bowel problems", and whichever way you'd rather broach the topic, we're happy to help! Gastrointestinal issues could be due to a range of causes, from simple infections, to more serious conditions such as bowel cancer. We run you through some of the red flags to look out for, with regard to bowel cancer. 

 

What Is Bowel Cancer?

Bowel cancer is the 4th most common cancer in the UK and tends to be diagnosed in the over 60’s (80%). The NHS sends out stool sample screening kits every few years to people considered at risk because of this. Bowel cancer is the general name for cancer of the large intestine, small intestine or rectum, but may also be known as colorectal cancer or colon cancer. Most cancers tend to develop in the large intestine rather than the rectum.

Bowel cancer occurs most commonly in the large intestine, although can also affect the small intestine and rectum 

 

Symptoms of Bowel Cancer

Most common symptoms include:

  • Bleeding from the back passage (rectum)
  • Blood in your stool
  • A persistent change in bowel habit
    • This usually means going more often with more frequent stools than normal
    • Thinner, more watery stools

Other bowel cancer symptoms include:

  • Persistent pain, bloating, discomfort in your abdomen
    • Especially after eating
  • A lump in your abdomen
  • Unintentional weight loss
  • Loss of appetite
  • Anaemia
    • A low level of red blood cells causing tiredness and/or breathlessness
  • Swelling of the stomach with vomiting

A change in your bowel habits, or blood in your stool, are the most common symptoms of bowel cancer

These symptoms quite often present in other conditions as well, so it’s important to see your affordable private GP if you notice any of them, particularly if they last a long time. The symptoms can be very subtle but will be persistent rather than being associated with anything you’ve eaten or done recently.

 

Causes of Bowel Cancer

There are various risk factors to look our for, that put peope at increased risk of developing bowel cancer:

  • Family history
    • Having a close relative (mother or father, brother or sister) who developed bowel cancer under the age of 50 puts you at a greater lifetime risk of developing the condition
    • Screening is offered to people with a close family history of bowel cancer, and you should discuss this with your GP
  • Inflammatory bowel diseases
  • Other risk factors:

Diets high in red meat are thought to increase the risk of bowel cancer

 

Screening For Bowel Cancer

Bowel cancer screening programs are available for people aged between 60 and 74. They involve you smearing a bit of stool on a kit provided through the post to detect any small traces of blood in the stool. Around 2% of people will have blood in their stool found by this test, but this doesn’t necessarily mean cancer, and so they will be invited in for further testing. This includes a colonoscopy (a flexible camera on a small tube put up the back passage) to look for any polyps or growths that may be abnormal.

In people with inflammatory bowel disease, screening will occur more regularly in the form of an colonsocopy The risk of bowel cancer increases with worsening inflammation and duration of disease.

If you go to your GP with symptoms, they may carry out several examinations and tests. These include:

  • Checking your abdomen and back passage for any lumps
  • Ordering a blood test to look for any anaemia
  • Arranging for hospital testing such as a colonoscopy  or a CT scan

A colonoscopy involves putting a flexible tube with a small camera attached up the back passage to look for the source of any bleeding and any unusual areas of bowel. Biopsies (small pieces of tissue) may need to be taken. A CT scan of the chest, abdomen and pelvis may also be taken to determine if the cancer has spread to any other areas.

Colonoscopy, Bowel cancer screening

 A colonoscopy involves putting a thin flexible tube into the large intestine, with a light and camera, to look for any abnormalities

 

Bowel Cancer Treatment

Treatment for bowel cancer can take a variety of forms:

  • Surgery to remove any polyps, growths or tumours
  • Chemotherapy, where drugs are given to shrink or kill tumours
  • Radiation, where radiation is given to shrink or kill tumours
  • Biological treatments that are used alongside chemotherapy to stop the spread of tumours

The type of treatment most suitable depends on the type of tumour and when it was diagnosed. While surgery is a good option to remove all of a growth, some drugs may need to be given to try and stop any one off cells from splitting off from the cancer and causing a cancer elsewhere (metastases). 

 

Bowel Cancer Prevention

The best way of preventing bowel cancer includes lifestyle, medication and screening interventions. Lifestyle modifications that may decrease the risk of developing bowel cancer include:

  • Minimising alcohol intake
  • Maintaining a good diet
    • Plenty of fibre
    • Low in red and processed meats
  • Exercising regularly
    • Physical activity is also associated with a lower risk of bowel cancer
  • Medications used to prevent bowel cancer will be prescribed by your GP

So if you're at all concerned about bowel cancer, don't hesitate in booking in a GP consultation at any of our private clinics. Our GP's will either arrange for the relevant tests to investigate suspected bowel cancer, or reassure you that your symptoms may be due to another condition. Either way, it's better to be safe than sorry: forget any unnecessary embarrassment and get checked out!
