It is probable that you have encountered colorectal cancer at some point in your life. This type of cancer begins in the colon or the rectum, depending on where it starts. Colon cancer and rectal cancer are frequently grouped together as a result of their numerous and similar characteristics.
It is imperative to be aware of the typical structure and function of the rectum and colon in order to develop a more thorough comprehension of colorectal cancer. In conclusion, the colon and rectum comprise the large intestine, which is a component of the digestive system. The gastrointestinal system is another name for this system.
The large intestine is primarily composed of the colon, a muscular tract that spans approximately five feet. How does colorectal cancer start, then? Colorectal cancers typically start to grow in the inner lining of the colon or rectum. These growths are referred to as polyps.
The preponderance of polyps are benign, or noncancerous. However, certain types of polyps have the potential to progress to cancer over time. The probability of a polyp developing into cancer is determined by the type of polyp. There are numerous types of polyps, including adenomatous polyps, hyperplastic polyps, and sessile serrated polyps. It is crucial to acknowledge this fact.
The development of a polyp may result in the growth of cancer into the wall of the colon or rectum. The wall of the colon and rectum is made up of many layers. The innermost layer is where colorectal cancer is known to start, and it can grow through one or more of the subsequent layers.
Cancer cells in the wall may eventually grow into lymph vessels or blood vessels. From there, they have the capacity to travel to lymph nodes in the immediate vicinity or to remote regions of the body. The extent to which a colorectal cancer has penetrated the wall and whether it has migrated beyond the colon or rectum determine the stage of the cancer.
In conclusion, it is crucial to remember that adenocarcinomas comprise the preponderance of colorectal malignancies. Cells that produce mucous start to generate cancer in order to lubricate the interior of the colon and rectum. When physicians discuss colorectal cancer, they are almost discussing this type.
Signet ring and mucinous subtypes of adenocarcinoma may have a more unfavorable prognosis than other subtypes of Adenocarcinoma. It is imperative that you promptly seek medical attention and investigate the signs and symptoms of colorectal cancer.
