Lung cancer, like keganasan other,
is the outcome of abnormalities the cell, which is unity important to the life
of the human body. Normally, the body maintains the control of the growth of
cells and system balancing so that cells can divide in the production cell
fresh only if there is a need for cells new. If the control system was
disturbed and balance the growth of cells that will produce the uncontrolled
and spread of cells that form the end into a mass called a tumor.
The Tumor has two categories, the
tumour is benign and ferocious. Usually, a tumor disorder can be lifted and
stationary in nature, they do not spread to organs other or part of the body. a
ferocious, grow bold and attack any other part or tissue of the body, allowing
entry of the cells the tumor into the system limfatik or blood circulation and
some other locations inside the human body.
Metastasis is the process difusi
cell-cell tumour and growth place a tumor at sites distant known as metastasis.
Because lung cancer tends to disperse or bermetastasis early after it was
formed, it is very dangerous and hard to treat cancer. While lung cancer can
spread to the organs of certain organs specified as the heart, bones, brain and
glands adrenal cortex is the site common for metastasis lung cancer.
Metastasis the tumour is made up of
the same kind of cells the tumor original. his is a position that is very
common for metastasis of a tumor in some part of the body. For example, if
cancer of his prostate spreading through the blood stream to the lungs, he
could not have lung cancer but cancer of his prostate the metastasis in the
lungs.
The exchange of gases between blood
and the air that we breathe if the role of the main lungs. Carbon dioxide is
taken from the blood stream through the lungs and oxygen from air blows to
penetrate into the blood stream. Bronkus is the air duct the main entrance to
the lungs the trakea. Bronkus different in a little bit the air known as
bronkiolus that ended up on the bag minutes called alveoli where the exchange
of gas happens. The walls of the lungs and chest is covered by a thin tissue
known as the pleura.
Lung cancer can result in some
parts of the lungs, but 90-95 percent of lung cancer is considered from cells
epitel; Cells that coats the air the big and the small (bronchi and
bronchioles); For this reason, lung cancer is called a tumor sometimes
broncogenic or karsinoma. (Carcinoma is a term other to cancer). Mesothelioma
is a type of cancer that develops from the pleura or rarely from supporting
tissues in the lungs, the blood vessels, for example.
The doctor may use some tests to
stage accurate lung cancer, covering the test chemical in the blood, CT scan,
MRI, x-ray, scan the PET and do a scan bone. the result is abnormal in the test
chemical blood can show metastasis in the liver or the bones and the process of
radiology can document the size of the cancer even scatter.
Staging lung cancer is very
important to determine how the tumor can be treated, because therapy lung
cancer who were made to stage certain. Staging a tumor is also serious in an
estimated prognosis of the patient, have the highest usually karsinoma have a
diagnosis of stage lower keganasan.
Cancer of the assigned steps in the
following:
-phase I - cancer is limited to
lungs only
-phase II and III, the cancer is
confined to the chest (with a tumor bigger and more persistent, classified into
phase III).
- phase IV - the cancer has
scattered from the chest and the rest of the body.
