Prayer Request - Dan's Grandma

We need prayers for Dan's grandma, Nana.  She's not doing well.  She's struggled in recent years.  She's had breast cancer.  It metasticized to a spot on her rib.  She did a low dose of chemotherapy for a year that killed the spot.  She's had problems with her red blood cells.  A bone marrow biopsy revealed she had a syndrome that is usually a precursor for leukemia.  She's been getting weekly shots to help her body make red blood cells and for the last year or more? has been getting monthly blood transfusions.  She's getting weaker and is needing blood more often.  They believe she might have leukemia now, but they won't be confirming with another painful hip biopsy.  Recently, she's been dealing with nausea and loss of appetite.  She's had weight loss.  She's sleeping a lot of the time now.  She says she's not having any pain though.  Would you please pray for her and for Dan's family?
