Tears As Badminton Star Lee Chong Wei Quits After Cancer Battle

Lee, a father of two, was diagnosed with early-stage nose cancer last year and after intensive treatment in Taiwan, said he was keen to play again.

But he hasn't trained since April and after missing a series of self-imposed deadlines to return to competition, his hopes of being eligible for next year's Tokyo Olympics were remote.

The three-time Olympic silver medallist said he now wanted to rest and spend time with his family, and even take his wife on a "honeymoon", a trip that has been delayed since their marriage in 2012.
