It is unclear what causes colon cancer. Cancer occurs when cells change the structure of the colon. Normal cells grow and divide in an orderly manner, ensuring a normal function. But sometimes this growth gets out of control so that cells divide excessively in a continuous manner. After a period of latency, such cellular aggregates continuously growing tumors form that can affect different sized portions of the lining of the colon or rectum.

1. Cancer changes in colon

Colon cancer often begins in the form of clusters of cancer cells, called polyps. They are located on the mucosa along the colon and has a shape similar to that of a mushroom. Rarely can flat or cancer changes grosmiea subdenivelate gut, in which case it is called “nonpolipoide injuries. It’s hard to ask Removal polyps and non-polypoid lesions. Can prevent colon cancer development.

2 Inherited genetic. Mutations that increase the risk of colon cancer

Genetic mutations that increase the risk of developing colon cancer is inherited, but it only happens in some cases Transmissible genetic mutations does not mean that a person will inevitably develop colon cancer. but the risk is higher.

3. Familial adenomatous polyposis

It is a rare disease that causes thousands of polyps on the lining of the colon and rectum. People with familial adenomatous polyposis have an increased risk of developing colon cancer before the age of 40 years.

4 Nonpolipozic possession. colorectal cancer

Also called Lynch syndrome increased risk of colon cancer before the age of 50 years, both familial adenomatous polyposis and colorectal cancer have nonpolipozic can be detected by genetic testing .. If there are cases of colon cancer in the family is shown that the doctor requires these tests to run

Treatment

The type of treatment depends mainly on the stage of the disease, the most important therapeutic methods. inverventia surgery, chemotherapy and radiotherapy.

Surgical treatment in the early stages of colon cancer or cancer

In small polyps at an early stage of elimination can be made using colonoscopy as pathological states that the tumor had invaded the polyp and its base. there is a greater chance that all the cancer completely removed. Other large polyps can be removed by laparoscopic surgery, operation performed by only a few small incisions in the abdominal cavity, incision through the video camera and instruments are introduced neceare surgery. The images are projected onto a screen Lymph node. biopsies can be collected and the affected area.

Surgical treatment of invasive colon tumor cancer

If the colon wall has grown, the surgeon advised colectomy the portion of the total removal by healthy tissue, the emergence and nearby lymph nodes analyzed later.

The surgeon may the two remaining portions. but if it is not possible, create a temporary colostomy (anus against nature). An incision is a hole in the abdominal wall skin that brings to a terminal portion of the colon to creates digestive evacuation in order to get into a special pocket for the next days, Soul after surgery is essential for healing Later anatomical continuity. of the colon to recover, but others may be permanent colostomy.

Surgical treatment of colon cancer found in advanced stages

If the crop is at an advanced stage and / or mood can be changed inverveni palliative operation to target the colon to decompress and relieve symptoms.

If there are only providing metastases in small numbers, the surgeon can perform surgery and must be removal of the liver it then. intervene by chemotherapy in many cases it can also be used for the operation. The combination of therapeutic means aimed at the chances of using drugs survival.

Chemotherapy

Chemotherapy certain cancer cells to death, can be applied to the remaining cells destroyed after surgery, tumor growth control or symptoms of cancer to reduce your doctor may recommend chemotherapy when. the cancer spreads beyond the bowel wall or lymph nodes. In people with rectal cancer chemotherapy associated with radiotherapy .

Radiotherapy

Radiation therapy uses X-ray sources of energy cancer cells that remain after surgery or colorectal cancer events.

Radiotherapy improvement is rarely used in its early stages to death, it is used in the early stages of colorectal cancer in the gastrointestinal tract and reach hole nodes. Radiation may be used after surgery and reduce the risk of cancer recurrence in the area initially biologically therapy

Actioneza interested.

Targeted existing drugs to specific defects in cancer cells destroys them, for those with advanced disease and may with chemotherapy or administered alone. such drugs bevacizumab (Avastin), Cetuximab (Erbitux) and panitumumab (Vectibix).

Some people are helped by these new drugs, while in other cases not getting the desired results. They are now busy establish patient profile, one or other of these drugs can have the best results. Until then, doctors carefully weigh the risk / benefit and not at the cost / benefit for the biological therapy is extremely expensive.
