Fisher was born on 24 February 1968 in Cheshunt and grew up in Tonbridge, Kent and lived later in Peacehaven, East Sussex. She started playing snooker when she was 7. She won her first world title at the age of 17. To date, she has won over 80 national titles and 11 world titles in total. Throughout the 1980s, she made various attempts to qualify for the main Men's snooker tour, which contained around 128 players at the time, but these attempts were unsuccessful. However, by 1991, the tour had changed considerably meaning all players had to do to become a 'professional' on the main tour was pay an entry fee. This meant over 500 players played in qualifying rounds for the ranking tournaments. Fisher reached round 4 of the qualifying rounds of the 1994 World Championship where she was beaten by Roger Garrett 10–4. She was unable to progress into the higher reaches of the ranking lists and by 1997 she lost her professional status. Feeling that she did not receive the same respect as the male players, she moved to the United States to play on the WPBA Tour. On 18 March 2009, she endorsed the Delta-13 billiard rack and has her own signature series.
