Tumor memes

A woman comes to the doctor and says, "Doctor, I think I have cancer." The doctor checks it out. "It’s all in your head," the doctor says. "Phew," said the woman. "A bunch of tumors, all in your head."

Dark humor is like cancer, it's even funnier when children get it.

The cancer patient asked the doctor how many more months he had to live. The doctor replied, "Tu-more."
