What is the difference between brain tumor and cancer?

 Conceptually, in a nutshell:

Tumors are cells that continuously divide without control, do not spread and do not attack other types of cells.

Cancer, on the other hand, is the opposite of a tumor. Cancer is a malignant tumor that has spread and attacks other types of cells in the body.

Through what do you spread it? Through blood.

Length:

These are brain cells. Think of these as normal brain cells. Just think of it because the original is not like this and is more complex.

Although low, normal brain cells have the unipotent ability to regenerate when there is damage. * Unipotent is the ability to develop into only one type of cell or tissue. This means that brain cells can only produce more brain cells.

For one reason or another these cells differentiate normally. * Dedifferentiation is the ability of tissue cells in the adult body that have differentiated to be able to mitigate again.

* Differentiation is the process of growing and developing cells towards special functions that are not owned by the original cell. For example, stem cells become brain nerve cells.

Due to differentiation, brain nerve cells increase, from 1 to 2, from 2 to 4, from 4 to 16 and so on.

As the population increases, normal cell division will stop differentiation due to membrane friction between cells.

Why is it so? Because when the membrane of a cell meets other cell membranes, the meeting will produce adhesion links.

What is adhesion linking?

Adhesion linkages are adhesion proteins of a cell with other cell adhesion proteins. This bond will make the cell population tight and compact. This direct contact process between the cell surfaces will stimulate the extracellular matrix of the surrounding cells, which has a gel-like structure.

Matrix is ​​one type of autocrine substance. * Autocrine substances are substances that are excreted by cells for the purposes of sepopulated cells.

The function of the matrix is ​​to reduce all members of the population to move and move away from the population. In order to stick with the term, nowhere.

In the matrix there is a khalon. Khalon is a kind of protein contained in the matrix or cell sheath. The function of this substance is so that the size and amount of an instrument is balanced with the volume of the body. For example, the normal brain size of a 7 year old child is 22mm, then the size will be adjusted so that the khalon is not more than that.

After the autocrine substance and adhesion protein are linked, each cell is connected to each other in contact inhibition bonds. So every cell that is bound in this bond, they must be compact, obey the rules of khalons and matrices.

Together forever ~ must be united, obedient, tolerant, tolerant, eh ... you can't be different, anyway.

Unfortunately, normal cells that turn into cancer cells can't be like that anymore. He lost control and broke the rules of khalon and matrix. They have apostatized from the population, live alone, create a new population that is different from the type of cell they originate from.

How to do?

The mechanism by which cancer occurs has three stages of change:

1. The initiation stage. At this stage, normal cells have the potential to turn into cancer cells due to stimulation of carcinogens (substances that trigger cancer) that enter the cells. The initiator then changes the DNA or through cell metabolism so that the DNA breaks. At this stage the change is irreversible. Cannot go back to the beginning.

2. The promoter stage. At this stage carcinogens will change initiated cells (normal cells that are entered) into cancer cells and are reversible (can return to the original).

3. The stage of change is permanent or progressive. This stage results in uncontrolled cell division, without the need for an initiator or promoter, cancer cells will produce angiogenesis factors, namely vascular growth factors for cancer cell nutrition. So later the cancer cells will make new blood vessels to feed the cells.

After all, what is the carcinogen so that normal cells can turn into tumors or cancer? They affect 4 groups of genes that regulate normal cell growth:

1. Growth genes are protocogens.

2. Growth inhibitor genes, namely anti oncogenes or cancer suppressor genes.

3. Cell death or apoptosis genes.

4. Genes repair DNA damage / DNA repair genes.

What is the result?

Cell growth becomes uncontrollable and will continue to divide, multiply, take nutrition from stem cells, even damage it. Anyway, they are not alone!

If cell growth or self only occurs at one point, then it is called a tumor.

But if the tumor has formed vascular tissue to nourish the cells and spread it through the blood, then the cells are called cancer.

So, stay away from things that trigger cancer!
