First, there are three ways in which you can keep chickens: 1  Free range Advantages: It's fun and you get to see the chickens run all around. 2  Limited range You can make up a fence (see fence section below) which will contain them. 3  Completely housed (in a coop) Advantages: Safety.
The USPSTF considers the following methods to be acceptable screening tests for colorectal cancer: 1  High-sensitivity fecal occult blood tests (FOBT). Both polyps and colorectal cancers can bleed, and FOBT checks for tiny amounts of blood in feces (stool) that cannot be seen visually. 2  Stool DNA test (FIT-DNA).
Blood Tests. Blood tests can evaluate the function of the gallbladder, liver, and pancreas. Levels of the pancreatic enzymes amylase and lipase can be measured. Blood tests can also check for signs of related conditions, including infection, anemia (low blood count), and dehydration. A tumor marker called CA 19-9 may be checked if pancreatic cancer is suspected.
