Answer 1

Step-by-step explanation:

Tumors of the brain are abnormal growth of cells inside the brain or in near proximity of the brain.Brain tumors are not always cancerous and the risk posed by them depends on their proximity to the brain & their size. The tumors could originate in the brain itself and their spread outward, known as primary brain tumors; or originate outside of the brain and penetrate into the brain - these are known as metastatic or secondary brain tumors. A lot of factors can contribute to the growth, proximity and type of brain tumors in an individual.
