Billiards star Jeanette "The Black Widow" Lee has come through her cancer treatments "like a champion," according to her agent, and now, her prognosis going forward has improved.
The 50-year-old pool legend was diagnosed with terminal ovarian cancer back in the winter ... and her friends at the time feared she only had months left to live.
But, Tom George -- who's been Lee's agent for years -- tells TMZ Sports Lee handled her treatments so well ... doctors have now told her she could live several more years.
