Occurrence Rates Of Different Types Of Colon Cancer
Published on Feb 02 2010, in the categories: Uncategorized
In order to understand what colon cancer represent we have to think about the tissues of the colon (the longest segment from the large intestine) and imagine it rancid. The colon cancer is also defined as colorectal cancer and it is a major death leading cause.
Almost 650 000 people die yearly from this disease and it is the forth commune form of cancer worldwide.
On the molecular and cellular level, the colorectal forms of cancer stars with a small mutation to the network of proteins, that are responsible for their roles in embryo genesis, called Wnt. When this Wnt is linked to the cell receptor, it sets a motion, a chain of cellular events that ends with the beta catenin that enters into the nucleus and activating a certain DNA gene that develops and encourages the apparitions of the cancerous cells. The colon and the rectal existing genes are attacked and damaged, creating new and more cancerous cells, which finally attack the healthy colon tissue and emerges in various forms.
Adeno carcinoma is of the most common form of colon cancer there is, and unfortunately there are many other forms of this disease as well. Examples include melanoma, leiomyosarcoma, neuroendocrine tumors and lymphoma. This excerpt will particularize the commune forms of the colon cancer.
Adenocarcinomas, being very known in the medical world through its bad reputation it a form of colon cancer that originates in the glands. This type of cancer is responsible for about 95 percent of all colon and rectal cancers and has two sub types, signet and mucinous cells. The first one, the signet cell sub type comprises 0.1 % of adeno carcinomas while the second one comprises about 15 percent.
The Leiomyosarcomas form is the type of colon cancer that occurs in a particular smooth muscle of the colon. Leiomyosarcomas is held responsible for less than three percent of rectal and colon cancers and are knows for their high chance of metastasis.
Colorectal lymphomas are fairly not that commune and have 75 percent chances to start around and in the rectum area then in the colon. Even though the lymphomas start in other parts of the body are predominantly found more spread to the coIon than the rectum. Non-Hodgkin’s lymphoma measures 0.5 percent of colon and rectal types of cancer and has numerous forms.
Melanomas as a type of colon cancer are relatively rare. In most of the cases the melanoma (The malignant tumor usually developed on the skin surface) starts elsewhere on the body and spread to the colon area. Melanomas account for a very small percentage, around one percent of all colon forms of cancer.
Neuro endocrine tumors are spitted in two important categories: indolent and aggressive. When there are large cells and small cells that act it is considered an aggressive form, and on the other hand carcinoid tumors in all its forms are called indolent.
