Colon cancer is the third most common cancer worldwide, the current lifetime risk of developing colorectal cancer about 1 in 23 for men and 1 in 25 for women [1].

When cancer begins to show symptoms, it can sometimes become harder to treat. With this in mind, as with all cancers, early screening is vital - it increases the chances of detecting and treating the cancer early before it begins to show symptoms and has the chance to develop.

How do you check for colon cancer at home?

There is no verified way to check for colon cancer at home - the only approved way to check for colon cancer is with a colonoscopy. That said, the most reliable way to screen for signs of colon cancer is with an at-home screening test.

If you’d prefer to screen from the comfort of your own home, LetsGetChecked’s at-home Bowel Cancer Screening Test can help identify the presence of cancerous or precancerous growths in the bowel by detecting blood that is invisible to the naked eye - our dedicated team of nurses are available 24/7 and will call you to explain your results.

Risk factors of colon cancer

According to the American Cancer Society, you should begin regular screening at the age of 45 or younger if you have a family history of colon cancer [2].

Some risk factors associated with colon cancer include[3]:

  • Being overweight or obese
  • Smoking
  • Heavy alcohol use
  • Older age
  • Family history
  • Diabetes

You can screen for colon cancer at home with LetsGetChecked’s at-home Bowel Screening Test. The purpose of this test is to identify the presence of blood in the stool, which may be invisible to the naked eye.

You should consider taking the test if:

  • You’re experiencing gastrointestinal symptoms
  • You have a history of adenomas (benign tumors)
  • You have inflammatory bowel disease* (which includes Crohn's disease and ulcerative colitis)
  • You have an inherited syndrome (e.g. Lynch syndrome/HNPCC or FAP)
  • You have type 2 diabetes
  • You have undergone radiation therapy

If you have already noted blood in the stool, you should speak with your doctor.
