Core Tip
Core tip: In the northern region of Brazil, gastrointestinal tumors are the second most frequent type of cancer among men and the third most frequent among women. These tumors are considered a serious public health problem because they are often diagnosed in advanced stages and have extremely low survival rates. Evaluation of family history to determine the number of relatives affected and genetic screening analysis are important preventive measures to assist in the early diagnosis of patients who have not yet developed the disease, as was the case of some patients analyzed in this study.
