Madrid  - Spanish former golfer Severiano Ballesteros was released from hospital Tuesday, after two months of inpatient treatment for a brain tumour.

"Ballesteros will continue to receive outpatient treatment from the Medical Oncology and Oncological Radiotherapy services," La Paz hospital in Madrid said in a statement.

The former golfer, 51, collapsed on October 6 at the Madrid airport and was subsequently diagnosed with a brain tumour. He was first operated on eight days later and has undergone surgery a total of four times.

Madrid  - Former professional golfer Severiano Ballesteros will undergo a second operation on his brain, doctors at a Madrid hospital said Thursday.

The 51-year-old had developed an oedema as well as a haemorrhage on his brain, they said, describing his condition as serious but stable.

During the operation on Friday doctors will also be removing some more of the tumour which had already resulted in an operation last week, but which could not be removed as it was in parts of the brain which were not easily accessible.
