All You Should Know About Cancer Cells
All You Should Know About Cancer Cells: To be able to easily understand what cancer is, regardless of its type, you first have to know how cancer cells are developed. Cancer cells are the cells that grow and divide in an abnormal manner. The development of cancer cells in the human body is actually quite common. Unhealthy and old cells are constantly developed. When they get damaged, the body replaces them with healthy cells. Well, cancer is formed when the body fails to recognize cancer cells and consequently, they are not replaced. Masses of cancer cells form tumors.
Why are cancer cells developed?
Commonly it has been considered that healthy cells fail to recognize the cancerous ones when the immune system is damaged or affected in a way. However, it is important to know that there are numerous theories out there regarding the reason why healthy cells fail to complete their normal evolution, leading to the development of tumors. Some specialists actually claim that this happens when there is a lack of some molecules which are able to aid this process. Others say that stem cells may also be turned into cancer cells, at least when there is a surplus of SP2 protein.
How are cancer cells developed?
The human body is formed by cells. Cells are actually considered to be the basic unit of life of all living organisms. The body contains both healthy and damaged or old cells. Healthy cells are produced constantly to replace the old ones. As more cells get old and damaged, other healthy cells are constantly formed. Well, when this process is affected, cancer is formed.
Cells that stop dividing in a controlled manner cause cancer. The disease is formed when healthy cells fail to recognize and replace the damaged ones. Old and damaged cells are not replaced by healthy ones, but healthy cells continue to be produced, even though the body does not need them. All these cells create masses of tissue. Shortly, this is how tumors are developed.
For the human body to function properly, the balance between healthy and old cells has to be normal. When this simple process is affected in a way or another, cancerous tumors are formed. Tumors can be benign and malignant.
Cancer cells have the ability to spread. This means that they can easily spread to other parts of the body, causing secondary tumors.
Understanding how cancer cells are formed is not that difficult. However, you first need to know how cells function and the process through which healthy cells replace the cells that die.
