The largest category of primary malignant brain tumors that arise from cells in the CNS are called <u>Gliomas</u>
A malignant brain tumor is a rapidly developing malignancy that can spread to the spine and other parts of the brain. According to their growth rate and propensity to recur after therapy, brain tumors are often rated from 1 to 4 based on their behavior. Grade 3 or 4 tumors are classified as malignant brain tumors, whereas grade 1 or 2 tumors are typically classified as benign or non-cancerous.
The majority of malignant brain tumors are secondary malignancies, meaning they first developed in another area of the body before spreading to the brain. Brain-originating tumors, or primary brain tumors, are those.

Demographers are scientists who study human populations. They tend to map and understand the dynamics of population, which includes birth, death, and migration. All of these affects population and must be studied by demographers. They may study the population change within a country or the interrelationship of countries' populations, which is mostly necessary in studying migration. However, they could also take specialization. For example, they could study only parts of the population like workers' social pattern. Demographers mainly use statistics in mapping their data.
Yes because you cannot establish credibility without a source that is experienced on the research topic. it would be like a janitor writing journals about brain surgery when he never went to school to get his doctorate degree and has no valid knowledge of the topic.
