We just learned a little about Malignant Tumor.
One of the six signs of Cancer is Cell Growth.
Usually in the human body, cells are created, they grow a little, and then they either split up into more cells, or they go away.
Sometimes cells don't do what they are supposed to, and they don't go away.
They just keep getting bigger and bigger, or keep dividing but not going away.
That can be a sign that makes some of the tumors we've learned about.
