Cal Ripken Jr.'s Iron Man streak is now his second-most awesome feat ... 'cause the MLB legend says he was able to beat prostate cancer in a matter of weeks!!
The 59-year-old told reporters Thursday he was diagnosed with the disease way back in February ... but, thankfully, he says he's been cancer-free since March surgery.
"The cancer was all contained in the prostate, they did a pathology report afterward and confirmed that that was the case," Ripken Jr. said.
"I’ve since had a three-month test to see if my PSA was undetectable and it was, so we can make a case that all the cancer was contained and it’s all out now.
