American choreographer, Abby Lee Miller, has been diagnosed with a type of cancer called, "Non-Hodgkin's lymphoma". The 'Dance Moms' star, who recently underwent a spinal surgery for an infection, was then diagnosed with the cancer. She posted a picture of herself on Instagram in a hospital gown and wrote, "So much gratitude and love for those who listened,those who looked deeper and those who leapt into action. So much more I wish I could say......about how quickly your life can change at the hands of others. Thanks for #abbyleemiller #abbylee #aldc #aldcla #aldcalways #dancemoms #iwilldance." Miller's spinal surgeon told that the reality star likely has Burkitt lymphoma, a type of Non-Hodgkin's lymphoma and that pathology results are still pending. The doctor's report also said he's unsure if the lymphoma has spread at this point.
