What is colorectal cancer?

Colorectal cancer is a cancer that starts in the colon or the rectum. These cancers can also be named colon cancer or rectal cancer, depending on where they start. Colorectal cancer is one of the three most common cancers with high incidence worldwide.

Colorectal cancer (CRC) is one of the five most common cancers in China and its incidence is still steadily increasing, which make it becoming a leading cause of cancer death for both men and women.
02 The mortality of colorectal cancer is closely related to the stage of disease at time of diagnosis. When caught early, colon cancer is almost 90% treatable. Most colorectal cancers start as growth of polyps on the inner lining of the colon or rectum. A polyp can take as many as 10 to 15 years to develop into cancer. With screening, doctors can find and remove polyps before they have the chance to turn into cancer, which means regular screening can even prevent colorectal cancer.
  • Early caught
  • Early diagnosed
  • Early treated
Colorectal cancer often doesn’t cause symptoms until it is advanced. Regular colorectal cancer screening is one of the most powerful weapons against colorectal cancer. When colorectal cancer is found early, before it has spread, the 5-year relative survival rate is 90%. People who get early screened are more likely to avoid the mental pain and high costs of advanced cancer treatment.
03 Colowell help you find precancerous lesions and colorectal cancer in its earliest stages. A variety of internationally leading molecular biological detection methods are used to analyze tumor markers of exfoliated cells in stool. Based on large-scale Chinese experiments and large data analysis, the risk of colorectal cancer and precancerous lesions is determined, so as to achieve the purpose of early detection and early intervention.
