ABC’s “Good Morning America” had an announcement today about the health situation involving the morning show’s anchor Robin Roberts, Entertainment Weekly reports.

Roberts, who will be having a bone marrow transplant as she battles a rare form of leukemia, announced that this Friday will be her last show for a while, the story reports. She is reportedly expected to be away from the show for months.

The report notes: “Roberts began to unravel the news this past weekend that her leave was impending when she tweeted about leaving her dog KJ with friends in Maine. This morning, Roberts told viewers that she is preparing to check into the hospital [for] treatments next Tuesday.”

Said Roberts: “It still takes about 10 days after being admitted because there are some things you have to go through before the (bone marrow) transplant actually occurs.”

The anchor’s sister Sally will reportedly provide the marrow for the procedure.

EW adds: “Throughout the week, ‘GMA’ will celebrate ‘Robin’s journey.’ Roberts, a breast cancer survivor, announced in June that she was suffering from MDS (myelodysplastic syndrome), a rare blood and bone-marrow disease. She told viewers last last month that she was anticipating a medical leave in late August, though she had not set a specific date until today’s confirmation.”
