Have You Heard About Colorectal Cancer?

Do you know that there are several types of cancer that involved gastrointestinal tract?

World Health Organization (WHO) regards cancer as second leading cause of death globally, accounting for an estimated 9.6 million deaths, or one in six deaths, in 2018 and the number of colorectal cancer patient is expected to increase by 60% to more than 2.2 million over the next 15 years.

One of the most common cancer that public are unaware of is Colorectal Cancer (CRC) even though it is the fourth most common cause of death from cancer, in which almost 700,00 was estimated to face cancer deaths. It is one of the most common cancer in men.

Cancer developed when abnormal cells in the body keep on growing and multiplying uncontrollably, forming a mass of abnormal cells called tumours which then invade nearby cells to expand and spread to other parts of the body.

Colorectal cancer is a cancer that starts in the colon or the rectum. These cancers can also be named as colon cancer or rectal cancer, depending on where they start. Colon cancer and rectal cancer are often grouped together due to their common features.

Most colorectal cancers start as abnormal growth (polyps) on the inner lining of the colon or rectum.

When tumor formed, they are capable of spreading into blood stream or lymphatic system (channels that carry away waste and fluid) enabling them to travel to nearby lymph nodes or distant parts of the body.

The stage (extent of growth and spread) of a colorectal cancer depends on how deeply it invades the wall and how far it spread outside its origin.
