Perhaps one of the words most used and most frightening when it comes to their health and reverse disease. Cancer is the term and is used for a group of diseases that have a common denominator: the transformation of normal cell into one that behaves very dangerous for human body.
The cell is the simplest element, endowed with life itself, which is organized tissues. It consists of a mass of protoplasm surrounded containing a nucleus.
A cell wall surrounds the cell and separates it from its environment. Inside the nucleus is the DNA that contains the information that programs the cell life.
Man is composed of millions of cells.
The cell divides and in doing so their structures are also divided into other exactly the same as above, with the same components and features than the original.
Normal cells grow at a rate limited and remain within their respective areas. Muscle cells are formed and grow in the muscles, not bones, those of the kidneys do not grow in the lungs, etc.
These functions and this growth rate is determined by the DNA. Some cells have less time to live than others, such as intestinal cells have a life span of two weeks while red blood cells live for about three months.
Other cells will live for the lifetime of the person and only divide to replace themselves, this would be the case of bone cells that act when it comes to repair a fracture.
The life of each group of cells is different and operate on it to make its DNA is different for each type of cell. Each cell is distinct.
The blood brings oxygen and nutrients necessary for cellular life and collect the waste products produced by cells and transported to the filtering and cleansing organs (kidneys, liver, lungs).
Lymph is a colorless liquid that is composed mostly by lymphocytes, a type of white blood cells and travels through the body through the lymphatic vessels.
The immune system is responsible for defending the body by white blood cells that seek and destroy bacteria and viruses.
Leukocytes travel in the blood and lymph and accumulate in areas where infection is to surround and kill the bacteria or virus and, later, migrate through lymphatic vessels to lymph nodes.
Lymph nodes are like clusters of grapes located in different parts of the body.
Each node receives the cell and this is where they are filtered and destroy bacteria, cell debris and worn themselves.
When an infection occurs, the lymph nodes may swell. If the infection occurs in a tooth, will ignite the neck. If the infection is in one hand, will be increased for those in the armpit. The lymph nodes also can be enlarged when a tumor.
Normal cell becomes a cancer cell to become due to a change or mutation in DNA. Sometimes these cells, whose genetic makeup has changed, die or are eliminated in the lymph nodes. But other times, still alive and reproduce.
The cancer cells look different, either because its form has changed or because nuclei contain larger or smaller.
These cells are unable to perform the functions that correspond to cells belonging to that tissue.

Pleurodesis is a process that is sometimes used to control the pleural effusion or concentration of fluid between the lung and the lining layer. Pleurodesis can close the spaces between the lungs and the outer layer, thereby reducing the possibility of accumulation of fluids.
There are two methods of pleurodesis. In the first, a tube inserted into the chest drain fluid. After the fluids have been drained, injected a sclerosing agent (a material that causes the tissue to heal and harden), such as a sterile powder like talc through the chest tube in the pleural space.
The second method uses a thoracoscopic pleurodesis, in which a small incision or several small incisions in the skin and a thoracoscope is inserted through them, to get a better picture of the pleura. The sclerosing agent is then applied.
Pneumonectomy
A pneumonectomy is the removal of part or all of the lungs. The surgeon makes an incision on one side of the chest. When the lung is found, the surgeon watches the tumor and then decide how much tissue should be removed.
Extra pleural pneumonectomy
This surgery usually involves removal of the pleura, diaphragm, pericardium and the entire lung cancer tumor side. The surgeon might also remove some of the surrounding tissues.
