Colon polyps: causes, risks, treatment

Polyps in the intestine are not automatically dangerous. However, they can lead to colon cancer. 

Colon polyps – briefly explained

  • Colon polyps are protrusions of the mucous membrane that occur mainly in the large intestine.
  • Most are harmless, but sometimes colon cancer can develop from them.
  • Polyps in the intestine rarely cause symptoms.
  • They can be identified and removed through a colonoscopy.
  • A healthy lifestyle prevents polyps.

What are intestinal polyps? Are they dangerous?

Many people have polyps in their intestines. The older you get, the more common they occur. Intestinal polyps are protrusions of the mucous membrane that protrude from the intestinal mucosa into the inside of the intestine – the intestinal lumen. They arise because more cells than normal grow in one or more places in the mucous membrane. The polyps are typically found in the large intestine, especially in the last section, the rectum.

Most colon polyps are benign, so colon cancer will not develop from them. However, some polyps can develop into colon cancer over the course of years. Initially, a tiny polyp forms – a polyp bud. This can increase over time. For various reasons, the polyp tissue can become malignant, usually over a period of many years. The cells in the tissue grow in an uncontrolled manner. This is known as colon cancer.

How cancer can develop from polyps:

How does colon cancer develop from an intestinal polyp? An initially tiny increase in tissue – the polyp bud – increases in size over time. For various reasons, the polyp can become malignant. Then the tumor tissue grows uncontrollably and displaces healthy tissue. Colon cancer develops. This can spread into the underlying muscle layer, which is permeated by blood and lymph vessels.

Cancer cells can get to other parts of the body via the vessels and lead to more tumours (metastases). If the tumour is not discovered and continues to enlarge, it can completely fill the interior of the intestine and thus close it. If it grows outwards through the entire intestinal wall (breakthrough), other organs can also be affected directly.

Classification of the types of intestinal polyps

There are different types of polyps. They differ in their shape and tissue structure (under the microscope):

  • Hyperplastic polyps: in the vast majority of cases, they are benign, sit directly on the mucous membrane and often look like a sawtooth.
  • Inflammatory polyps: do not degenerate and often occur in chronic inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis.
  • Harmful polyps: occur in people with hereditary syndromes and can develop in children.
  • Adenomas: are – besides the hyperplastic – the most common intestinal polyps and can be subdivided into further sub-forms. For example, they may look like a cauliflower and sit on a stem. But they can also lie flat on the mucous membrane or be a mixed form of both.

Once the polyps have been removed, the adenomas – also called adenomatous polyps – further differ in their appearance into tubular, villous, and tubulovillous adenomas. Furthermore, adenomas can look like a sawtooth (serrated adenoma). However, the doctor cannot reliably differentiate these polyp forms from one another during a colonoscopy, so the classification is always based on removal under the microscope. This also means that any polyps discovered must be removed.

Few adenomas develop into colon cancer. Nevertheless, they represent a preliminary stage of colon cancer, as doctors call the type of tumour. Because in over 90 percent of cases, colon cancer develops from adenomatous polyps. The more adenomas there are in the colon and the larger they are, the higher the risk of cancer.

In some people, there is a large number of adenomas in the large intestine, which are hereditary. This clinical picture is called familial adenomatous polyposis (FAP). Without early cancer screening, almost 100 percent of these people develop colon cancer.

What promotes intestinal polyps?

  • Allergies, could be diary, gluten, additives or foods that are inflammatory (sugar, transfats, veg oils, alcohol, processed meats, refined carbs)
  • Age: the older a person, the more often polyps are formed
  • Obesity: The higher the body mass index, the more likely it is to have polyps
  • little movement
  • low fiber food
  • eat red meat frequently
  • smoking
  • alcohol
  • Gender: Men are more likely to get polyps in their intestines than women
  • Hereditary predisposition: For family reasons, there can be a massive incidence of intestinal polyps, the polyposis syndromes. These include familial adenomatous polyposis (FAP) and serrated polyposis.
  • Lynch syndrome (hereditary non-polyposis colon cancer, HNPCC) is also hereditary and can cause colon cancer at an early age. This arises from individual polyps. Usually, there is a familial accumulation of special forms of cancer

Do they cause symptoms?

In most cases, intestinal polyps – especially small ones – do not cause any discomfort. It is rare for a polyp to bleed, which could be seen in the presence of blood in the stool. A larger polyp also rarely interferes with digestion. This could manifest itself as constipation, diarrhea, or a painful urge to defecate.

How does the doctor detect polyps in the intestine?

Colon polyps are usually discovered when the doctor does a colonoscopy. With the help of an endoscope – a kind of thin plastic tube – the gastroenterologist examines the inside of the colon. He can recognize polyps and remove them with a snare or forceps.

Even if most of these protruding mucous membranes are located in the rectum, experts recommend a complete colonoscopy – i.e. the entire colon. Because: If the doctor finds a polyp, more often occur. The colonoscopy is considered to be the best method to detect and prevent polyps and thus colon cancer.

Alternatively, there are tests for blood in the stool. You can recognize occult blood in the stool, i.e. blood that is not visible to the naked eye. The disadvantage: polyps can bleed, but don’t have to. That means: With this detection method, not all polyps and thus precancerous stages can be reliably identified.

Colon cancer early detection.

Men and Women from the age of 50 get a colonoscopy reimbursed by Medicare if the test for occult blood comes back positive. The test is sent out every 5 years. Alternatively, you can request the stool test annually from your GP.  Anyone who has an increased risk of colon cancer or symptoms will be reimbursed for the cost of the examination earlier and at shorter intervals.

How are they treated?

Medically, a doctor removes colon polyps during the colonoscopy. He or she uses special instruments, such as a loop, that are inserted through the endoscope. The tissue is then examined in a laboratory to check whether it is benign or malignant.

But you don’t immediately have to go to extremes. With regular care, you can keep your colon clean, which is of utmost importance when you have Polyps. Regular colonics will help.

Taking a psyllium-based product like AIM Herbal Fiberblend to gently and regularly clean the colon is most helpful. It is also important to have a good daily probiotic.

Supplements that are recommended when you have Polyps are:

  • Quercertin
  • Omega 3’s
  • Vitamin C
  • Vitamin A (good for the mucous membrane)
  • Vitamin E
  • B Vitamins
  • Selenium
  • Magnesium
  • Bromelain

Drinking enough water (3 liters per day) is also important to heal the mucous membrane.

Follow-up care of polyps

Colon polyps can develop again even if they were removed during the colonoscopy. The doctor will inform the patient when a check-up is advisable.

How can you prevent colon polyps?

The risk of getting colon polyps can be reduced. The same recommendations apply here as for colon cancer.

  • Be physically active: 30 to 60 minutes a day are enough.
  • Eat a balanced diet: Lots of vegetables and fruit, high-fibre foods such as oatmeal, legumes, whole grain products, little to no red and processed meat.
  • Drink little to no alcohol.
  • Do not smoke.
  • Pay attention to your weight.
  • Keep your colon clean by doing regular cleanses and colonics


Colonics are a great way to help keep your colon clean and support you in keeping up with a healthy lifestyle.
