I have a cancer growing on my head
I found it there one day
When alerted by a slight but constant itch
I scratched the surface off of it
Releasing future throe
The smart of which costs me
A piece of my life each day
I have a cancer on my head
Now swollen and sore
Its density deepens within my withering skull
Digging and drilling like a brain weevil it feeds
On what little there is left of me to eat
