Brain Tumor

What is cancer?

Cancer begins in cells that form tissue blocks. Tissue, organs of the body.

Normally cells grow and divide to form new cells that the body needs. When cells age, die and new cells take their place.

Sometimes this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when it is needed. These extra cells can form a mass of tissue called a growth or tumor.

What kind of benign and malignant brain tumor?

Brain tumors can be benign or malignant:

Benign brain tumors do not contain cancer cells:

In general, benign tumors can be removed, and rarely grow back.
The boundaries or edges benign tumor in the brain can be seen clearly. The cells of benign tumors do not invade tissues around them or spread to other parts of the body. However, benign tumors can put pressure on sensitive areas of the brain and cause serious health problems.

Unlike benign tumors, and in most other parts of the body, benign brain tumor, sometimes fatal.

Very rarely, a benign brain tumor may become malignant.

Malignant brain tumors contain cancer cells:
Malignant brain tumors are usually more severe and often fatal.

Likely to grow rapidly and crowd or invade the surrounding healthy brain tissue.

Very rarely, cancer cells can be removed malignant brain tumor and its spread to other parts of the brain, spinal cord, or even in other parts of the body. The spread of cancer is called metastasis.

Sometimes, a malignant tumor has not spread to healthy tissue. The tumor may be contained within a layer of tissue. Or the bones of the skull or another structure, there is no limit. This type of tumor is called encapsulated.

Assessment of tumor

Doctors sometimes group brain tumors by grade - low class (class I) high grade (grade IV).Score refers to the appearance of tumor cells under a microscope. The cells of high grade tumors look more abnormal and generally grow faster than the tumor cells of low class.
