Seve Ballesteros has revealed to the Spanish media that he has been diagnosed with a brain tumour. The 51-year-old collapsed at Madrid airport on Monday and was taken to hospital in the city, where he remained in intensive care while doctors conducted brain scans.

Ballesteros left La Paz hospital's intensive care unit on Saturday, before making the announcement about his condition on Sunday after informing his family.

The statement released to the Spanish media began by announcing Ballesteros would undergo a biopsy on Tuesday, saying: "The doctors will now decide how to proceed.

"Throughout my entire career I have been one of the best at overcoming obstacles on the golf course. And now I want to be the best, facing the most difficult game of my life, using all my strength and also counting on those who have been sending me get-well messages.

"Now I've been able to tell my three children personally and their mother, now I can tell you the illness that I am suffering from. After the exhaustive tests that I have undertaken in the Hospital La Paz (Madrid) they have detected a brain tumour.

"I have always sympathised with those people who face illnesses. Therefore, I want to remind them that with bravery, faith, serenity, confidence and a lot of mental strength, we have to face any situation no matter how difficult it is."

Ballesteros asked for his family's privacy to be respected while promising to keep people regularly informed of his condition.
