Polyps are often non-cancerous growths but some can develop into cancer. The two most common types of polyps found in the colon and rectum include: 1  Hyperplastic and inflammatory polyps.2  Usually these polyps do not carry a risk of developing into cancer. 3  However, large hyperplastic polyps, especially on the right side of the colon, are of concern and should be completely removed.olyps are often non-cancerous growths but some can develop into cancer.

Here are the facts: Most estimates say we have about 100 billion brain cells (neurons), and about ten times that many, or one trillion, support cells (glia) that help the neurons. We'll just concentrate on the neurons themselves. The brain weighs about 3 pounds, and after age 20, you lose about a gram of brain mass per year.
The human brain is composed of neurons, glial cells, and blood vessels. The number of neurons, according to array tomography, has been shown to be on average about 86 billion in the adult male human brain with a roughly equal number of non-neuronal cells.uch of the size of the human brain comes from the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought.
