Welcome To CTR 101
The abbreviation CTR stands for a multitude of things. Google will give you almost 100 full forms from ‘Click through Rate’ to ‘Cassette Tape Recorder’(do you remember those?).
But the CTR I write about stands for ‘Certified Tumor Registrar’. I presume 3/4th of the world has no idea about this profession. I was often met with blank stares when I told people I worked at a Central Cancer Registry *.
