*X-rays*
A radiologist is treating a patient with a malignant stomach tumor.
She must destroy the tumor but she cannot operate.
If the radiologist uses high intensity X rays to destroy
the tumor, she will destroy healthy tissue through which the X rays must
pass.
If less powerful X rays are used they will spare the
healthy tissue but will not be strong enough to destroy the tumor.
Question:
How can the radiologist destroy the tumor without damaging the healthy
tissue?

My thunder comes before the lightning.
My lightning comes before the clouds.
My clouds come after the rain.
My rain dries all the land it touches.

He has not lungs nor throat but still a mighty roaring call.
