What is colorectal cancer?
☞ Colorectal cancer refers to cancer that develops in the colon when cells of the colonic mucosa proliferate indiscriminately. When colorectal cancer is allowed to grows, lymph node metastasis may occur which allows the cancer to spread beyond the wall of the colon. It may even spread to the blood vessels, liver, and lungs.
The cause of colorectal cancer
☞ According to the World Cancer Report 2014 , published by The Interntional Agency for Reserch on Cancer (IARC), the specialized cancer agency of the World Health Organization (WHO), the rate of gastric cancer of Korea is 9.7%, which gives Korea the 3rd highest rate of gastric cancer in the world
The cause of colorectal cancer is mostly precancerous polyps. As the size of these precancerous lesions grows, they become cancerous. Thus, the most effective means of prevention is to remove the precancerous polyps.
Symptoms of Colorectal Cancer
Changes in bowel habits and rectal bleeding are the most common symptom.
Consultation with a specialist is needed since these listed symptoms are also symptoms of other diseases.
Abdominal pain and weight loss are symptoms of advanced cancer.
Unfortunately, polyps and early stage colorectal cancers are asymptomatic. Thus, regular colorectal cancer screening is recommended for persons over the age of 40.
☞ The most effective treatment of colorectal cancer is surgery. Chemotherapy or radiation therapy may be used in addition. It is very important to correctly treat colorectal cancer. The disease prognosis depends more on how early the cancer was discovered rather than what treatment has been chosen. Most of all, early detection of colorectal cancer is the most important factor for successful treatment.
