Incongruity

The chemo floor is laid out
In patterns meant to assure
Blue white blue blue white
Squares of a checkerboard

In this box of a building
They put lines into me
Running down straight poles
From rectangular bags

Into how many squares
Have I entered with hope
Watching white coats
Ponder slides and charts

All this to battle a world
Of the round and oblong
Spherical planets and tumors
Evading angular control
