He won 293 of 331 PSA Professional matches and 99 of 118 PSA Professional Tour Finals matches. From 1990 to 1996, he remained unbeaten in 81 matches, which Guinness World Records recognizes as the longest winning streak in top-level professional sports.^[8][9]

Jansher Khan had his first major success in 1986 as the winner of World Junior Squash Championships in Australia when he was aged 16. Same year, by defeating Australia's Chris Dittmar, he won the Senior World Open tournament. At 16, he became the youngest winner in squash history by defeating world No. 1 Jahangir Khan in the Hong Kong Open. He went on to defeat Jahangir Khan 7 more times that year.Jansher Khan began his career as an employee of the Pakistan Air Force.^{[citation needed]} During his career, he won 293 of 331 PSA Professional matches, and 99 of 118 PSA Professional Tour Finals. From 1990 to 1996, he was unbeaten in 81 matches, a record six years; his longest winning streak is recognized by Guinness World Records as the longest in top-level professional sports.^[8] By comparison, his main competitor Jahangir Khan won 134 of 164 PSA Professional matches and 61 of 80 PSA Professional Tour Finals and was unbeaten in 70 matches for five years from 1981 to 1986.

Jansher Khan retired from squash in 2001.^[10] In late 2011, he was diagnosed with Parkinson's disease. In 2020, after suffering from severe back pain while praying and walking, Khan underwent successful double back surgery at Shifa International hospital in Islamabad, Pakistan.^[11][8]

Jansher Khan offered the following advice to young players after his successful surgery:

"I would advise today's young players that along with their hard training they must take special care of their back, knee and groin injuries and treat minor ailments timely to avoid serious problems in future."^[8]

In September 2020, at the request of the Chief Minister of Khyber Pakhtunkhwa Mahmood Khan, Jansher Khan joined the Directorate General Sports Khyber Pakhtunkhwa as head squash coach.^[12]

Upon his appointment, Jansher Khan stated, "I will do my best to fill the gap created in the game of squash and make the country a new world champion."^[2]

Jansher Khan's main rival was his fellow Pakistani, Jahangir Khan. During the 1980s and 1990s, the two athletes dominated the sport, collectively winning 14 World Open titles and 16 British Open titles.
