chronic myelogenous leukemia
"I was diagnosed in May 2014 and started taking Sprycel within the week. After 6 months I was at .01% of the BCR-ABL abnormality.  Great results, right?  But I felt awful.  After dealing with minor side effects of acne, sore breasts, weight gain and a low mood, the severe fatigue and chest pain were enough to stop.  I'm now on Gleevec and starting to experience extreme thirst and weight gain.  

Very grateful there are medications that treat CML but frustrated with the inevitable side effects."
