Beneficial bacteria and dangerous bacteria. What are the signs of bowel cancer?

Medics should identify the first signs of bowel cancer using instrumental methods of a visual examination of the walls of the colon. They should use sound or ray methods without penetrating the body.

The basis for assigning studies

The basis for assigning instrumental or laboratory studies are:

  • risk groups;
  • Age over 40 years, but there are cases of the disease in the younger generation;
  • The presence of some signs indicating a lesion of the gastrointestinal tract as well as of any other symptomatology. For example, a combination of cardiac and excretory disorders against a background of intestinal disorders is also on the symptoms list.

The competent vigilance of a general practitioner plays a critical role in cancer diagnosis during this period, as people turn to the therapist in the early stages of the disease in 70-90% of cases, often for reasons unrelated to cancer.

What are the signs of bowel cancer and recommendations for prevention?

The doctor usually thinks about the possible layering of oncology with the appearance or intensification of the following subjective sensations in the patient (at least three at a time).

The signs of bowel cancer:

  • general weakness;
  • fast fatiguability;
  • pain in a particular anatomical area of the abdomen (see the anatomy of the intestine above);
  • progressive weight loss;
  • a slight but persistent increase in body temperature;
  • blood or mucus in the faeces;
  • faeces of dark (black) colour;
  • the pallor of mucous membranes and skin;
  • lack of relief after effective medical manipulation.

Naturally, these signs are not an accurate indication of cancer. So, always consider the patient’s suspicion, the individual threshold of pain sensitivity and other clinically significant parameters for diagnosis. The clinical, instrumental and laboratory studies clarify the diagnosis when the doctor confirms the patient’s complaints.


To list the first macro- and microscopic changes in the intestinal wall, which diagnostic physicians find in surveys, is inappropriate in this article since such knowledge is purely professional.

Oncological diseases are devious as well as unpredictable. Do not expect when signs of bowel cancer to appear. In short, it is worth pondering in advance about prevention.

General recommendations concern the correction of lifestyle, including this:

  • increased physical activity;
  • enrichment of the diet with products containing fibre;
  • colonic irrigation;
  • Rejection of bad habits (smoking, drinking alcohol).
