Surgery, chemotherapy, radiotherapy and other methods
The colorectal group includes cancer of the rectum and colon. Moreover, neoplasms are mainly formed in the colon - about 70% of cases. If the disease is diagnosed at an early stage, it is relatively easy to treat. And even at later stages, there is a high chance of successful treatment.
The Humanitas Clinic Oncology Center diagnoses and treats colorectal and colon cancer. In addition, patients are provided with comprehensive treatment for other forms of the disease, including Pates-Jeghers syndrome, Lynch syndrome, adenomatous polyposis, and others.
High results are achieved by using an interdisciplinary form of diagnostics and treatment. Oncologists, gastroenterologists, surgeons and a number of other specialists are involved in order to study the disease as accurately as possible and find the appropriate treatment in a specific case. Leading radiotherapists, nutritionists and other specialists take part in diagnostic procedures.
This approach allows us to guarantee each patient the best possible prevention, diagnostics and treatment options available today. Moreover, each patient is provided with professional psychological support if necessary.
Risk factors and symptoms of the disease
The disease can develop without any obvious prerequisites. However, scientists identify a number of factors that can provoke colorectal cancer:
- bad habits: smoking and alcoholism;
- excess weight, obesity, sedentary lifestyle;
- the patient has chronic inflammatory bowel disease;
- heredity.
In the vast majority of cases, colorectal cancer occurs in people over 50 years of age. But it can also occur in younger people (about 10% of cases).
The disease is most common in Europe, Australia, North America and New Zealand. In Russia and the CIS countries, colorectal cancer is one of the leading oncological diseases in terms of the number of patients.
You should contact a doctor immediately if the first symptoms appear:
- Shortness of breath and severe fatigue even with little exertion.
- Atypical paleness of the skin for a person.
- Frequent and prolonged constipation or diarrhea.
- The appearance of blood in the stool.
- Discomfort or pain in the abdomen.
- Decreased appetite and rapid weight loss.
- General weakness and malaise.
The problem with early detection of cancer is that the symptoms are often mistaken for the result of another disease. Most patients do not immediately seek medical attention to get diagnosed. As a result, treatment almost always begins at stage III-IV of the disease.
Conducting diagnostics and treatment
One of the most effective methods of diagnosing the disease is colonoscopy – an endoscopic examination that allows diagnosing the disease at the early stages. Colonoscopy makes it possible to assess the internal state of the intestine, detect a neoplasm or even precancerous conditions, such as polyps or ulcers. When cancer is detected, the stage of the disease and the presence of metastases are determined. For this, ultrasound, computed tomography and magnetic resonance imaging are performed.
People at risk are strongly advised to undergo regular cancer screening – a preventive examination that allows detecting various forms of cancer at the earliest stages, even before the first symptoms appear. This will allow for timely additional diagnostics and treatment.
As for the treatment itself, the most effective for many years has been surgical removal of tumor tissue. Small neoplasms that are localized in a polyp are best removed surgically. This operation can be performed directly during a colonoscopy. If this method is not possible, an operation is performed using transanal endoscopic microsurgery. In more complex situations, removal of part of the intestine may be required. Almost always, such operations are performed using a minimally invasive method to minimize trauma and speed up recovery after surgery.
The second effective method of treating colorectal cancer is chemotherapy. It is applicable at all stages of the disease and is often used in combination with other methods. Almost always, chemotherapy is necessarily carried out after surgery to reduce the risk of tumor recurrence in the future. In the late stages of the disease, chemotherapy is used to slow the progression of the disease and the formation of metastases.
The third effective method is radiation therapy. Radiation is most often used before surgery to reduce the size of the tumor and make the surgeon's work easier. Sometimes it is also used after surgery to sterilize the area where the tumor was.
