Kanye West and his dad are making the best of a bad situation ... turning Ray's recent cancer diagnosis into a reason for some quality father-son time.
Sources close to the family tell TMZ ... there's been a major silver lining to Kanye's father receiving treatment for prostate cancer in L.A. -- Ray's been able to spend time with him, Kim and his 3 grandkids.
We're told while Ye and his Pops have never had a bad relationship, it's just been distant with Ray living in Chicago. So, they're taking advantage of the situation now, which has allowed them to bond.
We broke the story ... Kanye dropped everything to get his father the best medical treatment possible in L.A. once he got the cancer news.
And, from what we've heard, Ray's responding well to treatment and it looks like he's going to be okay.
