Davina McCall says she felt her benign tumour "had taken control of me and I was so angry about that" following her diagnosis last year.
The Masked Singer judge shared with followers in November last year that a colloid cyst had been found after she was offered a health check-up as part of her menopause advocacy work.
She had surgery to remove the tumour, and spent time in intensive care before recovering from home with the help of her partner, celebrity hairdresser Michael Douglas.
According to the NHS, non-cancerous brain tumours are more common in people over the age of 50, and symptoms include headaches, vision problems and drowsiness, and some can be "difficult to remove without damaging surrounding tissue".
