There is a space between the lungs and the body wall. This is called the pleural space.

There is usually not much there at all since the lungs occupy that space in the chest. Maybe just a small amount of fluid that helps with lubrication.

Fluid build up in the space is called pleural fluid. First you might need to know what the fluid itself is.

Is there any sign that the cancer has spread to the lungs? This would be called metastasis. And it is a very poor sign.

Sometimes, cancer spreads to the lung itself or to the outside of the lung around the edges between the lungs and the body wall. Sometimes, this causes pleuritis, or inflammation.

Infection can also find it's way into that space, and the fluid that builds up is usually like pus.

Sometimes pressure from tumors in the lungs, or pressure from fluid backing up into the lungs from heart failure for example, can lead to that fluid pushing it's way out into the pleural space. This fluid is often sort of clear, and resembles plasma, or the clear portion of blood without the cells. They tend to stay inside blood vessels with this kind of fluid.

Sometimes, damage to the lung itself, from a tumor, a puncture, rupture can cause actual bleeding. In this case, the fluid will look very much like blood, in fact it is..

The only way to know is to aspirate the fluid like you were asking. SO the answer is YES!

That will allow your Veterinarian to look at the fluid on a microscope and test it's consistency with a few other tools to get a better understanding of the problem.

If it is clear fluid, it can be removed easily.

If it is pus, it would require chest drains to help get the pus out.

If it is blood, this is a very bad sign, and could mean there is bleeding inside the chest cavity that needs to be stopped. It is not easy to get out, and shouldn't really be removed. The bleeding needs to be stopped.

If the cancer has spread, the chest tap through thoracocentesis (putting a needle in and pulling out fluid) would only be a stop gap measure I am sorry to say. Unfortunately, it might not prolong life for very long. But, if your friend Ruby is having trouble breathing, it might help there.

Ok Mary. Sounds good.

Hopefully something can be done to help Ruby breathe easier. I hate cancer with a passion. It would be nice to have some better treatments.

If anything else comes up in the future, please feel free to contact me. And if I have helped don't forget to leave a rating.
