How long it takes for bowel cancer to progress from discovery to advanced stage is not certain, it needs to be viewed in the context of the specific situation, and can generally range from a few months to more than ten years or even decades.
Bowel cancer progresses from discovery to advanced stage in different ways due to the differences in many aspects such as its growth site, individual differences, pathologic type, invasion and scope and treatment, etc. Some people may take a few months, while some may take several years or even decades.
Bowel cancer is associated with the continued action of a number of oncogenic factors. Carcinogenic factors will lead to the proliferation of intestinal mucosal epithelium, which will generally progress from mild atypical hyperplasia to moderate atypical hyperplasia to severe atypical hyperplasia, and finally to the cancer stage, which is a relatively lengthy process, and can last from a few years to a decade or even to several decades.
Therefore, it is recommended that people who find bowel cancer in early stage should not delay, but should immediately seek medical treatment for active treatment, and usually have regular medical checkups.
