Paris Jackson Reconnects with Mom Debbie Rowe After Breast Cancer Diagnosis

Debbie Rowe just found out she must undergo chemo and radiation to fight her breast cancer that was recently diagnosed -- but if there is a silver lining, it's that the illness has brought Paris Jackson back into her life.

We've learned Paris -- who went radio silent on Debbie 2 years ago -- has been spending time with her mom since we broke the story last month she's fighting breast cancer. Paris has been visiting Debbie at her ranch and Debbie has gone to Paris' home, where the 2 have reestablished their bond. They're also texting ... a lot.

Debbie and Paris became very close after Paris' dad, Michael Jackson, died back in 2009. But a couple years ago Paris cut all ties ... wouldn't even return Debbie's calls.
