April is Testicular Cancer Awareness month. There are two ways for detection.
You can fondle the family jewels yourself for early detection, or you can do it my way. My way consists of three parts:
a) the (not always female) urologist fondles the remaining one.
b) recurring ultrasounds where a doctor, instead of searching for a baby, has you imagine taking ball selfies.
c) recurring CT scans, where you're pumped full of radioactive crap, have a machine slice you up into images, and hope not to light up like a Christmas tree.
Choise is yours. But, start fondling.
