Ali Carter is planning to return to snooker in October at a low-profile tournament in Bulgaria.
The 35-year-old Essex cueman has been undergoing chemotherapy after being diagnosed with lung cancer in May.
Carter, the two-time former World Championship finalist, intends to be back in action at the European Tour Players Tour Championship event in Sofia, which runs from October 3-5.
Carter wrote on Twitter late on Wednesday night: " I have entered my first tournament today, the PTC in Bulgaria!!"
He is battling cancer for a second time, after being cured of testicular cancer last year.
Carter has finished his course of chemotherapy for the lung condition.
He added on the social network: "H opefully got my last treatment next week, which is radio frequency ablation to burn the remaining tumour away! Then I will be brand new.
"So #watchoutworld I have nothing to be afraid of anymore! And nothing I can't achieve..#beatingcancer #forthesecondtime"
Carter lost to Ronnie O'Sullivan in his two Crucible finals, in 2008 and 2012, and is a former winner of the Welsh Open, Shanghai Masters and German Masters.
