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.

Answer:
50 years
Explanation:
The first human spaceflight named Vostok 1 was launched on April 12, 1961. This spaceflight took along with it Yuri Gagarin, a Cosmonaut who came from the Soviet Union. Thus this scientist was the first to ever travel to space and enter into orbit.
The formal end of the space shuttle program was marked in August 31, 2011. The last shuttle, STS-135 that was flown by Atlantis was retired on July 2011. So the time duration between the first human spaceflight and the end of the space shuttle program spanned some 50 years.
