Oncology: intestinal cancer

Colon cancer or a colon tumour is a dangerous disease that requires serious complex treatment.
The determination of the diagnostic method remains with the doctor. Colonoscopy with biopsy and analysis for occult bleeding is most often used. Pathological examination of tissue fragments is mandatory for making a diagnosis of a polyp or cancer of the rectum and colon. Without pathological studies, it is impossible to distinguish a benign tumour (adenoma) from a malignant (carcinoma). The quality of pathological research is of tremendous importance since the error in its implementation costs the life of the patient. The tumour marker CEA (cancer-embryonic antigen) is used in monitoring the disease with high efficiency.
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 stage of cancer is beyond doubt, the consultation of experts at the oncological conference takes a decision on the treatment tactics. Surgical treatment, irradiation of a tumour (both before and after surgery) is used. Chemotherapy is carried out 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, and may have the following signs:

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

As a tumour grows, cancer shows signs more clearly than in the initial stage. Symptoms to suspect cancer of the cecum include dizziness, tachycardia, general weakness, discolouration of faeces and rectal bleeding. Usually, carcinoma of the cecum is accompanied by aching, constant pain in the right lower abdomen. Oncology: bowel cancer is one of the most common among gastrointestinal cancers. For the prevention of pathology, it is recommended to monitor the state of your health, as well as carry out colonic irrigation.
