Colorectal cancer happens when cells lining the rectum or colon look abnormal. In addition, they go out of control. Symptoms of colorectal cancer do not appear until it has reached an advanced stage. This is the main reason why one must have regular screenings for colorectal cancer.
Early detection of Colorectal Cancer
At the early stage, screening can help to detect colorectal cancer. During this time, it will be small and easy to treat. As a result, regular screening will help in preventing colorectal cancer.
A polyp will take ten to fifteen years to grow into cancer. At the time of screening, doctors can remove these polyps. This will allow them to eliminate any chances of them turning into cancer,
If colorectal cancer is found early, then it will not spread. This is why the survival five-year rate will increase to ninety percent. However, only four out of ten colorectal cancers are detectable at this stage.
Diagnosis of Colorectal Cancer
Doctors diagnose colorectal cancer through a screening called colonoscopy. During this procedure, your doctor will examine the lining of your colon to look for tumors or polyps. If there are any polyps, they will remove them immediately.
Normally patients receive medication for helping them to relax at the time of colonoscopy. Many people will sleep through the entire procedure. After waking up, they will have little recollection of the test.
For colonoscopy, the doctor will insert a thin, long, and flexible colonoscope through your rectum into the colon. This tube will have a small light and video camera to transfer images to a monitor. It will help the doctor to view your colon.
Treatment Options for Colorectal Cancer
The treatment of colorectal cancer depends on its different stages. These stages will determine how severe the cancer is. The most common treatments are radiation, chemotherapy, and surgery.
