Brain tumors are abnormal cell growths in the brain that can be malignant (cancerous) or benign (non-cancerous). The type of brain tumor depends on the tissue it comes from and there are over 120 different types. Brain tumors are abnormal cells that grow in the brain. And they can grow from many different types of tissue. Brain tumor cells differ from normal brain cells in many ways. Which includes.
DNA
Brain tumors develop when the DNA in brain cells changes. Through which the cells receive new instructions to grow and multiply faster than normal.
cellular hierarchy
Brain tumors have a cellular hierarchy similar to the normal hierarchy of nerve cells. But with some differences. For example, stem cells from a brain tumor can give rise to various differentiated progeny. But the patterns of differentiation are less distinct than in the normal brain.
Interaction with other cells
Brain tumors can interact with other brain cells, such as astrocytes. Which can release fatty acids that activate signaling pathways in cancer cells. This can create conditions for cancer cells to survive and grow.
Brain cells differ from tumor cells in several ways, including their size, growth rate, and how they affect neighboring cells:
cell size: Cancer cells are usually larger than normal brain cells.
Growth rate: Cancerous brain tumors grow quickly and can spread to other parts of the body. Noncancerous brain tumors grow slowly and rarely spread.
Effects on surrounding cells: Cancer cells invade neighboring tissues, unlike noncancerous tumors. Brain tumors can be cancerous or non-cancerous and are also called malignant or benign brain tumors, respectively. Symptoms of brain tumors vary depending on the type of tumor, its size, location, and growth rate.
Some symptoms include:
Headache
Dizziness
double vision
convulsions
To vomit
weakness or paralysis
hearing, vision and smell problems

A doctor may perform a biopsy, spinal tap, or other tests to determine if a brain tumor is cancerous.
