Meningiomas are the most common kind of brain tumor — accounting for about 30 percent of all brain tumors — and most are treatable. In fact, the majority of these tumors can be removed surgically, and many do not return.
How do meningiomas differ from other brain tumors?
Meningiomas arise from the layers of membrane that cover the brain and spinal cord, not from the brain tissue itself. Some 90 percent of meningiomas are benign — that is, they are not likely to spread throughout the body — and they tend to grow slowly over months or even years.

The best procedure for your situation may involve a craniotomy, which is surgically making a temporary window in the skull and removing the tumor through that opening. The opening is repaired at the end of the surgery. The incision is usually behind the hairline and is not obvious once it heals.
Observation means seeing a neurosurgeon and having imaging tests done periodically. There are cases in which the meningioma is found incidentally and is causing no symptoms, and the neurosurgeon may recommend watchful monitoring or observation. Treatment may be necessary later, for example, if the tumor grows or symptoms develop or worsen.
Radiation therapy is the treatment of tumors using X-rays and other forms of radiation (light energy) to destroy cancer cells or prevent the tumor from growing. It is also called radiotherapy. Radiation therapy may be used to treat meningiomas that are malignant by location, which means that although the tumor itself may not be pathologically cancerous, the tumor’s location is dangerous. For example, a meningioma may form around the carotid artery. Skull base meningiomas can also be difficult to operate on due to their location. In these cases, radiation therapy might be used post-surgery to radiate residual tumor in precise areas of the brain.
Post-surgery, all patients receive a comprehensive assessment for neurological and cognitive needs. Learn more about care and recovery after surgery.
After surgery, a patient may require assistance in recovering. Rehabilitation specialists at Johns Hopkins will provide assistance with physical therapy, occupational therapy, and speech language pathology. Learn more about the rehabilitation services offered at Johns Hopkins Meningioma Center.
Surgery is the most common treatment for a meningioma. If a meningioma is benign and in a part of the brain where neurosurgeons can safely completely remove it, surgery is likely to be the only treatment needed. For some, total resection surgery is all that is needed for treatment, followed by periodic imaging to monitor any recurrence of a tumor.
Kieran McCrory, 37, was diagnosed with terminal brain cancer and was told he had about three to five years to live. Radiation treatment left him so physically exhausted and sick that he tried using cannabis oil as an cancer treatment instead. McCrory says the treatment (cannabis oil) literally saved his life.
“When I don’t have it, I lie in bed and think I’m going to die,”he said. “Once I got CBD(the cannabis oil)I started taking it in my coffee and cooking with it. Within the first 24 hours my whole game just picked up.”
Symptoms of Meningioma
Meningioma is a tumour that usually begin arising from the meningeal tissue of the brain (a tumour that forms on the membranes that covers the brain and spinal cord inside the skull). Meningiomas grow on the surface of the brain (or spinal cord), and therefore push the brain away rather than growing from within it. These tumors can become quite large with diameters of 2 inches (5cm)

Beyond the positive effects cannabis oil has had on his daily well-being, McCrory says doctors told him his tumor had stopped growing after he began taking cannabis oil. While medical marijuana isn’t legal in all countries and states around the world and those laws should yet be reviewed, McCrory says “there is a growing body of evidence that shows cannabis can effectively kill certain types of cancer cells”.
