Doctors in Madrid, Spain have confirmed that Seve Ballesteros's brain tumor is malignant. Ballesteros will undergo another surgery to relieve swelling and bleeding . In addition, the remaining parts of the malignant tumor will be removed.

Doctors have said that the surgery will be very complex. Based on an analysis of cells already removed, the tumor is classified as an oligoastrocytoma, a type that affects “cells that cover and protect the nerve cells in the brain and spinal cord,” the hospital said.

Ballesteros is divorced from his wife, Carmen Botin. Botin is the mother of his three children. His girlfriend, Fatima Garlaza, was killed in a car accident.
