Cancerous (malignant) tumors in the small intestine are very uncommon, occurring in about 9,000 people in the United States each year. Adenocarcinoma is the most common type of cancer of the small intestine. Adenocarcinomas develop in the glandular cells of the lining of the small intestine. People with Crohn disease of the small intestine are more likely than others to develop adenocarcinoma.
Test Overview. A brain natriuretic peptide (BNP) test measures the amount of the BNP hormone in your blood. BNP is made by your heart and shows how well your heart is working. Normally, only a low amount of BNP is found in your blood.
Your doctor will call them B-type natriuretic peptide (BNP) and N-terminal-pro-BNP (NT-pro-BNP). Levels of both in your blood go up when your heart failure gets worse and go down when it gets better. A test called a BNP blood test measures those two important levels. Itâs able to spot heart failure more than 80% of the time. Why Is a BNP Blood Test Needed? BNP levels help your doctor figure out if you have heart failure or something else that has similar symptoms such as shortness of breath. The test also shows if your heart failure has worsened.
