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).
CBC test: Complete blood count (CBC) tests may be used to measure different types of cells in the blood. A CBC test may be particularly helpful in determining whether you have too few red blood cells, which causes anemia. This may be a concern for colorectal cancer patients, because it may indicate that they have a tumor thatâs been bleeding for some time.
