During bone marrow biopsy, under sedation
and local anesthesia, a long needle is inserted into the hip
bone and some of the
marrow inside the hip bone sucked in. This marrow is then tested to find the cause of any blood disorder. Tyrosine Kinase Inhibitors are myelosuppressive drugs or they are drugs which suppress the bone marrow. This treatment is reserved for patients who do not respond to conventional therapy, as in your mother’s case.
