A Review on Causes and Treatment of Colorectal Cancer
Colorectal cancer is also known as rectal cancer, colon cancer, bowel cancer or colorectal adenocarcinoma. It is a type of cancer which occurs due to an uncontrolled growth of cell in the colon or rectum (parts of the large intestine) or in the appendix. The method of genetic testing has revealed the fact that colon and rectal tumors are usually the same cancer. Typically the symptoms of colorectal cancer include anemia rectal bleeding. It also sometimes associated with weight loss and changes in bowel habits.
Causes of Colorectal Cancer
In most cases, this cancer occurs due to changes in lifestyle and increasing age factor. Though genetic syndromes are considered among the most curial factors for increasing the chances of this cancer, there are a very few cases in which genetic is found to be the cause of this cancer. It typically starts in the lining of the bowel. If it is not treated in the beaning, it grows into the muscle layers underneath, and then through the bowel wall. It also occurs when tumors form in the lining of the large intestine (large bowel). The chances of colorectal cancer increase when a person turns 50. It is common both for men and women.
Colorectal cancer is a type of cancer which can spread in the body. This is because sometimes the cancer cells break away from the malignant tumor and enter the lymphatic system or bloodstream through which they travel to other parts of the body. It also spreads in the body through white blood cells that fight infection. When cancer spreads or travel from its origin in the colon to another part of the body such as the liver, it is called metastatic colorectal cancer. Sometimes people are mistaken to call it liver cancer.
Curable and Incurable Cancer
The category of colorectal cancers that are confined within the wall of the colon can be cured with colon surgery. On other hand, the cancer which spreads or travels widely around the body is usually incurable. According to a study, colorectal cancer is supposed to be the third most diagnosed cancer in the world. However, it is more common in the developed countries.
Diagnosis of Colorectal Cancer and Colon Surgery
These days, there are various treatment options to cure this cancer. If a colon cancer is detected at its early stage, there are greater chances of successful treatment with surgical procedure. During the procedure, surgeons first diagnose this cancer via tumor biopsy which is done during sigmoidoscopy.
Then, surgeons determine the extent of the cancer by doing a CT scan of the abdomen, chest and pelvis. There are other procedures to diagnose the canters such as PET and MRI. With the help of TNM system the nature of the canter is determined such as - how much the initial tumor has spread, where lymph nodes are involved, and how many metastases there are. Once a surgeon determines extent and causes of the cancer, he performs surgery and takes out the infected cell from the body.
To conclude, there are many health care centers in Singapore, where you can meet highly experienced colon surgeons. If you have symptoms of this cancer, consult a surgeon and get the proper medical treatment.
