The Sex And The City: The Movie star uploaded a snap of a computed tomography (CT scan) machine and told fans that he was worried about what the check would show up.
In a series of posts on his Twitter.com account, he wrote, "Faith!! Now it's not in my hands anymore! Wishing good results, and that is all. It's definitely not the best experience ever. Waiting for the results. Just keeping positive."
After several hours, Marini returned to his page on the microblogging site to reveal that the scan had not shown up any tumours and he had received the all-clear from doctors.
He added, "Just got the results!! All clear! I am so happy. The last 3 weeks have been pretty brutal in my mind! No tumor..."
