Masses of cells.
Malicious or benign
But no one ever tells
Them they’re out of line

Groups of children standing
Static in the halls
They are so demanding
We can’t get by at all

A tumor blocks a passageway
So nothing else gets through
And yet, the stand there everyday
It’s really nothing new

The hallways are like veins
For people, like blood, to pass
But clots don’t let the liquids drain
How can we get to class?

Tumors and clots bring danger
To all that they infect
So when things are getting stranger
Some obstructions you might detect

So remove the tumor please, my friend
And when I come, step back
If I can’t pass you, in the end
I’ll cause a Heart Attack!
