Cancer that begins in the colon is called colon and cancer , which begins in the rectum is rectal cancer . Cancers affecting either of these organs may also be called colorectal cancer.
This is a disease (cancer) , malignant cells form in the tissues of the colon first .
The colorectal cancer occurs in the rectum or large intestine .
This type of cancer occurs when abnormal cells grow on the inner walls of the colon and rectum .
These abnormal cells are typically present as polyps .
The polyps develop as a projection of the wall tissue of the colon , remains connected to the colon wall of a thin rod . Its shape is similar to that of a mushroom .
Polyps are very common, especially among the elderly.
The vast majority of polyps are not cancerous .
However, some polyps may become cancerous.
Unchecked , cancerous polyps results in a tumor growing in size until it penetrates the intestinal wall and involves the adjacent organs and the lymph nodes through the process of metastasis .
type
Generally , colorectal cancers tend to grow slowly , gradually increased and finally penetrate the wall of the intestine. When they do spread , usually by the invasion of nearby lymph nodes .
On the right side of the store near the colon , cancers usually develop in the space inside the colon .
They can become large enough to be painful and may cause bleeding. In these cases, the anemia of chronic blood loss is often the first sign and the reason for stool test for occult or hidden blood is important.
Most polyps and cancers appear on the left side of the colon . In the left or down , where the channel is narrow colon cancer tends to grow around the colon wall and surrounds .
Cancer left normally constricts the intestinal canal , causing partial obstruction.
symptoms
Symptoms may include :
• Diarrhea , constipation , vomiting, fatigue.
• Go to the bathroom more often.
• A feeling that the bowel does not empty properly after a bowel movement .
• Pain and swelling of the abdomen.
• Blood in the stool.
• Unexplained weight loss .
• A lump in the abdomen.
• unexplained iron deficiency in men or in women after menopause.
causes
• alcohol.
• Polyps .
• diabetes.
• The age and sex.
• high cholesterol diet .
• Inflammatory bowel disease (BD ) .
• Genetics .
• Lack of exercise .
• Smoking .
• obesity.
• Many adenoma polyps develop in the colon , ultimately leading to cancer.
• A family history of cancer.
• The effects of the drug.
diagnosis
Someone is diagnosed with colorectal cancer as follows :
• It is in a test routine .
• The symptoms lead a person to the doctor and tests to find the cause of symptoms indicate colorectal cancer.
treatments
These treatments may include, alone or in combinations :
• Surgery - Surgery options include:
A . Intestinal resection : This operation involves cutting into the abdomen to reach the area of the colon or rectum that is affected by cancer. The surgeon cuts the cancer and parts of the colon or rectum that are next to him . Then , the two healthy ends of the colon or rectum are sewn.
Two . Liver Resection : In this operation, the surgeon cuts the cancer has spread to parts of the liver and liver which are cut near the cancer .
Up to half of your liver can always be eliminated and the rest is in good health.
If liver cancer is too large to be removed through surgery , you may be given chemotherapy to shrink the tumor . If the tumor is small enough back , it can be removed by surgery .
Three . Lung , adrenal or ovarian resection , depending on where the cancer has spread .
If the cancer has returned to the intestines , the greater the colon or rectum may need to be removed.
• Chemotherapy: -
The chemotherapy may be recommended before surgery in some cases , even though limited to liver metastatic disease appears.
Chemotherapy after surgery can prolong survival for people whose cancer has spread to nearby lymph nodes .
The way the chemotherapy is given depends on the type and stage of the cancer being treated .
If surgical removal of liver metastases is successful , additional chemotherapy is usually recommended after surgery.
• Radiation therapy: -
Radiotherapy is not commonly used in this type of cancer because it could lead to radiation enteritis , and it is difficult to target specific positions of the colon.
It is more common to use radiation in the rectal cancer, since the rectum will not move as far as the colon, and is therefore easier to target.
If the treatment is administered prior to surgery , radiation therapy can reduce the size of the tumor.
This can improve the chances that the tumor was successfully removed .
Radiation before surgery also appears to reduce the risk of recurrence of cancer after treatment.
• Targeted therapy : - Therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells are used . A monoclonal antibody therapy is a form of targeted therapy used in the treatment thereof .
• Muncher: This treatment improves the body's immune system and increases the probability that cancer cells are killed .
• Monoclonal antibodies : - These antibodies are proteins produced in the laboratory that can identify a cancer cell to kill or inhibit tumor cells from dividing.
• Gene therapy : - This therapy is to modify the genetic material. Preferably a new gene is introduced to improve the ability of the body to kill cancer cells or a gene is delivered directly to the cancer cells , causing them to fall .
Getting the right gene into the cells in the body is a major challenge.
The treatment is still experimental and in its early stages of development.
Cancer of the colon and rectum is common.
The risk of developing colorectal cancer in patients with ulcerative colitis seems to depend on the duration of disease , severity of disease history , family .
More importantly, patients should be informed of the risk of developing colorectal cancer.
Recent advances have guidelines for colorectal cancer screening to be refined .
They also suggested to improve the quality and the implementation of testing tools . Reduces both the occurrence of colorectal cancer and mortality have occurred and are considered to be attributable to the efforts of detection.
