<human>: Can you give me a shortened version of the text?

Our five year old labrador retriever is scheduled to have surgery to remove a small, cancerours tumor tomorrow. My wife loves this dog more than anything in the world. He helped get her through the death of her father after his 3 year battle with cancer.

For the last week, our lab has been throwing up pretty much every meal, and his normally chipper mood is pretty reserved.  I have a feeling that his being sick is unrelated to the small tumor that is getting removed, but my wife obviously thinks that his cancer has spread and he's dying.

She literally cries everyday. To make matters worse, she is 8 months pregnant with our first child.  I'm truthfully more worried about the baby's response to a borderline depressed mother.

After the surgery tomorrow, they are going to send the tumor out to see if it is (1) nothing to worry about (2) bad but caught in time or (3) very bad.  The vet said that it's likely #1 or #2, but he seemed to be manging expecations and left open the possibilitly of #3. So, I need to get my wife through the next 3-4 days until we find out if we need to continue worrying.  I would love to hear any advice.

Thanks...
<bot>: My wife's 5 year old yellow Lab may have cancer, and she can't function at work.  She's also pregnant with our first child. What should I do to help her feel better?
