There are a number of different tests that can be used to diagnose blood cancer.
A complete blood count determines the numbers of RBCs, WBCs, and platelets in the blood.
Examination of blood under a microscope can also determine if the cells have an abnormal appearance.
The news that acclaimed actor Kirron Kher (also a BJP MP) has been diagnosed with multiple myeloma - a type of blood cancer - came as a shock to the nation's people. That Ms Kher is undergoing treatment and is in fine hands was tweeted by her husband and actor Anupam Kher, who also conveyed the same on the behalf of son Siddharth Kher.
