45 is no age. As a former cocaine addict I could empathise and wonder how much damage that disgusting and horrible drug did to her. I remember her on the Frank Skinner show in around 2002 and she was completely out of it but she seemed to turn her life around after that.

No knowledge that cocaine causes cancer . . . unlike heart disease . . . looks like a massive dose of lifestyle-unrelated bad luck....
The brain tumour was non-malignant although having it removed and the stress must have impacted on her health.
