She added, "well, my red blood count just kept falling, and they found out my iron /b12/ folic acid numbers were actually fine."

The star confirmed that she underwent a bone marrow biopsy, which led to the discovery of 'Waldenstrom Macroglobulinemia.'

"It's causing my body to be pretty severely anemic, and I feel it," the star described.

ET also reported that the Mayo Clinic describes "Waldenstrom Macroglobulinemia" as "a rare type of cancer that begins in the white blood cells," a "type of non-Hodgkin's lymphoma."

This disease causes bone marrow to produce "too many abnormal white blood cells that crowd out healthy blood cells."

Monroe finished her statement by saying she is "THANKFUL for friends and family who have gathered around me praying and sending flowers and letting me lean on them during this super weird chapter of my life."

Just as she admitted that she "was hesitant to post about" her illness, she concluded her post by writing that she believes in the power of healing through prayer and love.
