In human body, every day, millions of cells are died and new ones reproduced instead of them. This is a very important and necessary process to continuation of our lives healthy and normally. If this process demolished, diseases which called as cancer, begin to occur.
This process can demolish due to many different mechanisms, and when it happens, diseases which called as cancer begin to occur.
a. Genes and Cell Regeneration
The process of death and the
reproducing is carried out by means of the codes that located inside the cell.
These codes regulate the speed and amount of reproducing, at the same time,
also determine how cells behave. These codes are called genes.
b. How the cancer occurs?
However, the process of dying
and producing of cells is under a highly critical balance. Sometimes, due to
deterioration in the structure and genetic of the cells, they begin to increase
their numbers uncontrollably, and because of this, they also cannot perform
their tasks properly.
Because of this uncontrollable
situation, cancer which defined as a disease of cells, building blocks that
form a tissue in the body.
What is the kidney cancer?
A normal cell should die when it grows old somehow get damaged. However, because of the mutations in the genes, tumors develop if this condition deteriorates.
While, this is not the case in tumors. Because of the mutation in the genetic code of tumor cells, they all the time tend to proliferate and multiply themselves, without ever die.
Thus, if all of these processes develop in the cells of the kidney, masses named as tumors are formed and kidney cancers arises.
a. Where does kidney cancer starts?
Almost all types of kidney
cancers appear as carcinoma.
Carcinomas are tumors which originating from cells that cover the both inner or outer areas of the body.
As, in the kidney, carcinoma usually begins to develop in the cells covering the renal tubule. This tumor is called as Renal Cell Carcinoma (RCC) and it almost constitutes 90% of kidney cancer types. Therefore, the word “kidney cancer” usually refers to RCC.
b. What are types of kidney cancer?
Also, apart from the Renal Cell Carcinoma, other less common 3 types of tumors can be seen. But, they do not similar to Renal Cell Carcinoma, development and the clinical principles of them are very different from the Renal Cell Carcinoma (RCC).
The 3 less
common types of kidney cancer can be counted as Transitional Cell Carcinoma (TCC),
Willms Tumor and Renal Sarcoma.
From these types of cancers;
TCC actually develops frequently in the bladder and may sometimes occur in the renal pelvis.
Willms tumor is a pediatric tumor, thus almost always occurs at a young age.
Sarcoma develops from connective tissues which supporting the kidney or blood vessels which nourishes the kidney.
