The human colon, or bowel, could be a muscular, tube-shaped organ measurement concerning four feet long. It extends from finish of the little viscus to the body part, some doctors might embrace the rectum because the end of the colon. The term body part describes this space that begins at the colon and ends at the porta.
Typically, the primary or right portion of the colon that is named the colon moves up from the lower right portion of the abdomen. subsequent portion, or colon, moves across from the proper to the left aspect of the higher abdomen. Next, the third region or colon moves down the left aspect of your abdomen. Then associate degree S formed or sigmoid flexure portion of the massive viscus connects the remainder of the colon to the body part, that ends at the porta. this text can concentrate on the colon and fewer on the rectum; but, the terms colon, colorectal, and body part square measure thought-about interchangeable during this general article.
The colon has 3 main functions:
> To digest and absorb nutrients from food
> To concentrate soiled material by gripping fluid (and dissolved salts, conjointly referred to as electrolytes) from it
> To store and management evacuation of soiled material

Cancer is that the transformation of traditional cells. The reworked cells grow and multiply abnormally.
> Left untreated, these cancers grow and eventually unfold through the colon wall to involve the adjacent body fluid nodes and organs. Ultimately, they unfold (metastasized) to distant organs love the liver, lungs, brain, and bones.
> Cancers square measure dangerous due to their ungoverned growth and potential for unfold. They overwhelm healthy cells, tissues, and organs by taking their chemical element, nutrients, and space.
> Most colon cancers square measure adenocarcinomas-tumors that develop from the glands lining the colon’s inner wall.
> These cancers, or malignant tumors, square measure generally said as body part cancer, reflective the actual fact that the body part, the tip portion of the colon, may also be affected. Anatomic variations among the part as compared to the rest of the colon want that these areas be separately recognized by many investigators.
In the United States, one in seventeen folks can develop body part cancer.
> Per reports from the National Cancer Institute, body part cancer is that the third commonest cancer in U.S. men.
> body part cancer is that the second commonest cancer in U.S.A. girls of Hispanic, yank Indian/Alaska Native, or Asian/Pacific dweller ancestry, and therefore the third commonest cancer in white and African yank girls.
> the incidence of body part cancer accrued till 1985 then began decreasing at a median rate 5% annually in folks 50 and older from 2009-2013 (available data).
> Deaths from body part cancer rank third when respiratory organ and prostatic adenocarcinoma for men and third when respiratory organ and carcinoma for ladies.
> Death statistics from carcinoma vs. body part cancer isn’t clear as associate degree calculable four-hundredth of body part cancers square measure misdiagnosed as carcinoma (another reason for lumping them along numerically).
