Take On the Colon Cancer

Colon cancer is the third most common cancer in incidence and mortality worldwide (Fearon et al., 1990), and one of the few cancers that can be prevented. Fortunately, this disease often starts from the beginning with abdominal pain and symptoms. 

Less than 10% of patients in stage I disease recurrence and does not benefit for whom adjuvant chemotherapy, 20% of patients in stage II disease have a recurrence and for whom adjuvant chemotherapy minimal benefit (Marshall, 2010) because in the early stages of colon cancer (stages I and II) tumor engulfed all the inner walls of the colon. In stage III colon cancer there are regional lymph node metastases and the administration of adjuvant chemotherapy have been seen a significant increase in survival (Meyerhardt et al., 2005). In stage IV colon cancer patients are with distant metastases, tougher regimes in the process of receiving treatment that is not common treatments (Boland et al., 2016).
