Question
Colon cancer is caused by the accumulation of multiple gene mutations that result in uncontrolled cell division and growth. Arrange the following steps of colon cancer progression. Colon tissue is initially healthy. Polyps or early adenomas are formed by mutations in APC. Activating ras mutations gives rise to intermediate adenomas. Cancerous adenomas are generated by mutations in p53. Cancerous adenomas become metastatic by unknown mutations, Late adenomas are formed by the inactivation of DCC and Smad4. Colon cancer invades neighboring tissuesExplanation / Answer
