The brain is composed of millions of cells. These cells are formed by about 7 years of age after birth. When these brain cells cease division, they never divide. You can see that brain cell division is strictly regulated. When control is lost in one unit, it begins to split in an uncontrolled way. All data obtained through cancer research indicate that this disease is caused by rapidly dividing cells and there is nothing to prevent regulatory agencies from breaking it.
Brain tumors - Brain tumors can be roughly divided into two types. Primary brain tumor occurs in the brain. Metastatic brain tumor begins at the rest of the body and moves to the brain. According to the American Brain Oncology Association, brain tumor is the most common solid tumor in children, the second most common malignancy in children. Brain tumors are the second leading cause of cancer-related deaths in men under the age of 40 and are the second leading cause of cancer-related deaths in women under the age of 20.
There are various kinds of brain tumors. Some brain tumors are noncancerous (benign), and some brain tumors are cancerous (malignant). Brain tumors may arise from your brain (primary brain tumor), or cancer may originate from other parts of your body and spread to your brain (secondary or metastatic, brain tumors). Acoustic schwannoma (neuroma) is a well-balanced auditory nerve, a benign tumor that progresses from the inner ear to the brain. These nerves intertwine to form the vestibular cochlear nerve (the eighth cranial nerve). Stress from the tumor to the nerve may lead to hearing loss and imbalance
Benign brain tumor is non-cancer. Malignant primary brain tumor occurs in the brain, usually grows faster than a benign tumor, invasively invades the surrounding tissue. Brain tumors rarely spread to other organs, but they can spread to other parts of the brain and the central nervous system. Benign brain tumors usually have clear boundaries and usually do not enter deep into the brain tissue. Assuming that it is located in an area of the brain that can be operated safely, this will facilitate removal by surgery. However, even after they are removed, benign tumors are less likely to recur than malignant tumors, but they may still recur.
