Why are cancerous growths that originate in the brain more likely to be composed of neuroglia than of neurons?

Expert Solution
Step 1: Introduction:

Cancer is an illness caused when cells divide wildly and spread into encompassing tissues. Malignant growth is brought about by changes to DNA. Most cancerous growth causing DNA changes happen in areas of DNA called genes. These progressions are likewise called hereditary changes. Malignant growth can begin anyplace in the human body, which is composed of trillions of cells. Typically, human cells develop and separate to shape new cells as the body needs them. At the point when cells develop old or become harmed, they pass on, and new cells have their spot. 

At the point when cancerous growth occurs, in any case, this systematic cycle breaks down. As cells become an ever increasing number of anomalous, old or damaged cells survive when they should pass on, and new cells structure when they are not required. These additional phones can partition ceaselessly and may shape developments called tumors. 

Numerous malignant growths create solid tumors, which are masses of tissue. Cancers of the blood, for example, leukemias, by and large don't shape solid tumors. 

Malignant tumors are dangerous, which implies they can spread into, or attack, close by tissues. Also, as these tumors develop, some cancerous cells can break off and go to distant spots in the body through the blood or the lymph framework and structure new tumors a long way from the first tumor. 

In contrast to threatening tumors, benign tumors don't spread into, or attack, close by tissues. Benign tumors can now and then be very huge, in any case. At the point when taken out, they ordinarily don't develop back, though harmful tumors at times do.
