Oncology: intestinal cancer

Oncology: bowel cancer or a colon tumour is a dangerous disease that requires comprehensive treatment.

Doctors must determine the diagnosis method. They most often use colonoscopy with biopsy and analysis for internal bleeding. Pathological examination of tissue fragments is mandatory for diagnosing a polyp or cancer of the rectum and colon.

Without pathological studies, it is impossible to distinguish a benign tumour (adenoma) from a malignant tumour (carcinoma). The quality of pathological research is of tremendous importance since an error in its implementation can cost the patient’s life. The tumour marker CEA (cancer-embryonic antigen) allows efficient monitoring of the disease.

Cases

Oncology: bowel cancer is diagnosed by the most informative method for the study of PET-CT(Positron emission tomography-computed tomography) in the following cases:

• determining the stage of the disease in patients with single metastases, for example, in the liver or lungs;
• to decide on the possibility of surgical intervention if necessary;
• In case of suspected recurrence of the disease.

Oncology: Bowel cancer and its signs

When the diagnosis of bowel cancer and the tumour stage are beyond doubt, the consultation of experts at the oncological conference decides the treatment tactics. Doctors may use surgical treatment or irradiation of a tumour before and after surgery. They also carry out chemotherapy following internationally accepted standards.

Rectal cancer does not show specific symptoms. Colon cancer may also not show symptoms. The manifestation of signs of colorectal cancer depends on the stage of the disease. Thus, intestinal cancer may not show any symptoms, but may have the following symptoms:

• anaemia;
• The feeling of discomfort and pain in the abdomen.
• bloating;
• constipation or, conversely, diarrhoea;
• blood in the stool;
• Weight loss and general malaise.

Cancer shows signs more clearly as a tumour grows than in the initial stage.

Symptoms

Symptoms to suspect cecum cancer include dizziness, tachycardia, general weakness, discolouration of faeces and rectal bleeding. Usually, aching and constant pain in the right lower abdomen accompanies carcinoma of the cecum.

Oncology: Bowel cancer is one of the most common gastrointestinal tumours. For the prevention of pathology, doctors recommend monitoring the state of your health, as well as carrying out colonic irrigation.
