A brain tumor occurs when cells in the brain start growing abnormally. Some tumors are not harmful (benign), while others can be dangerous (malignant or cancerous). Brain tumor surgery is a procedure where doctors try to remove the tumor to help the patient feel better. The surgery depends on the tumor's size, type, and location.
Before surgery, doctors use tests like MRI or CT scans to see the tumor. During the surgery, the patient is given medicine (anesthesia) so they don't feel any pain. The surgeon makes a small opening in the skull to reach the tumor. In some cases, only a portion of the cancer can be removed if it is located in a problematic area.
After the surgery, the patient may need additional treatments, such as radiation or chemotherapy, to target leftover tumor cells. Recovery can take time, and patients may need physical therapy to help them regain strength. The goal is to remove as much of the tumor as possible without affecting important brain functions.
Symptoms of a brain tumor depend on its size, location, and growth rate. Common signs include:
