A brain tumor (sometimes referred more commonly as brain cancer) occurs when a group of cells within the brain turn cancerous and grow out of control, creating a mass. There are two main types of tumors : malignant (cancerous) tumors and benign (non-cancerous) tumors. [ 2 ]
Removal of tumor tissues helps decrease the pressure of the tumor on nearby parts of the brain. [17] The main goal of surgery is to remove as much as possible of the tumor mass while preserving normal brain function, and to relieve the symptoms caused by the tumor such as headache, nausea and vomiting.

A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord. They are malignant but some are extremely slow to develop. [2] [3] Gliomas comprise about 30 percent of all brain tumors and central nervous system tumors, and 80 percent of all malignant brain tumors. [4]
It is the most common cancer that begins within the brain and the second-most common brain tumor, after meningioma, which is benign in most cases. [6] [15] About 3 in 100,000 people develop the disease per year. [3] The average age at diagnosis is 64, and the disease occurs more commonly in males than females. [2] [3]
Oligodendrogliomas are a type of glioma that are believed to originate from the oligodendrocytes of the brain or from a glial precursor cell. They occur primarily in adults (9.4% of all primary brain and central nervous system tumors) but are also found in children (4% of all primary brain tumors).
Even if you tend to wake up feeling a little groggy, what you eat for breakfast can boost your brain health and provide enough energy to get you through the morning. "Luckily, we actually have a ...
Cordotomy involves cutting nerve fibers that run up the front/side (anterolateral) quadrant of the spinal cord, carrying heat and pain signals to the brain. Pancoast tumor pain has been effectively treated with dorsal root entry zone lesioning (destruction of a region of the spinal cord where peripheral pain signals cross to spinal cord fibers ...
However, it is an option only for patients with surgically resectable tumours; it cannot be used to treat DIPG. [22] Osmotic blood–brain barrier disruption (BBBD): The cells of the blood–brain barrier are shrunk by a concentrated sugar solution . This opens the barrier and allows 10 to 100 times more chemotherapy to enter the brain.
