MADRID, Spain (AP) -- Seve Ballesteros' brain tumor is cancerous and he will undergo another operation. La Paz Hospital said Thursday that the surgery is "of great complexity." The procedure Friday is designed to relieve pressure on his brain caused by swelling and bleeding that have recently developed.
The remaining parts of the malignant tumor, located in a very deep part of the brain, will be removed. The hospital says Ballesteros was in a stable, though serious, condition prior to the operation. A study of cells already removed has revealed the tumor is classified as an oligoastrocytoma. That type affects "cells that cover and protect the nerve cells in the brain and spinal cord," the hospital says.
