In the same way as our body is composed of hundreds of categories different of cells, the hundreds of cancers exist. If this illness is among the more dreaded, does one know for as much his mechanisms? Why are some tumors cancerous, of other not? To what moment does one speak of metastases?
Every cell contains in his core of the instructions as genes. During the formation of the human being, each differentiates itself and use a certain part of the genetic information only that she contains for his renewal and his death. But he sometimes arrives that the cellular mechanism stopped himself. A cell to the infectious madness
Definition of the cancerSi the relative instructions to his reproduction and to hiss death are altered, the cell can begin to divide in an uncontrolled manner. and to become immortal. Every newly created cell contains the mistake and product of the abnormal proteins. These proteins say "oncogéniques" are at the origin of the anarchical behavior of the cell.
As the abnormal cells increase more quickly than the healthy cells, they can form a heap named tumor or lesion. While winning in surface, he can construct himself the blood vessels that are going to supply it in oxygen and nutriments.
The tumor can control its size and cannot migrate circa other organs, in this case, it will be said cancerous or benign. If she invades the around organs she is said shrewd or cancerous.
The cancerous cell distinguishes itself thus by these two : an uncontrolled and anarchical multiplication associated to the possibility to colonize cloths or organs of which it is not originally descended.
And if the cancer spreads?
The cancerous cells can themselves étendrent to the around organs but they can also enter in the blood flux and colonize distant organs. Once to destination, they develop themselves as the original tumor. This process is named metastasis.
After this stage, the odds of recovery are weaker because the scattered tumors are more difficult to eliminate.
What are the treatments?
The place of origin of the cancer often depends the speed of propagation, as well as the resistance to the treatment. The therapeutic balance requires a precise diagnosis and the consultation of a medical team regrouping different specialties. More the tumor is detected precociously, more the treatments will be able to be efficient.
