Treatment for fluid on the lung

I am about to have a procedure to remove fluid from around my lung and put talcum powder in. Do I really need this?

The lungs are covered by 2 sheets of tissue called the pleura or pleural membranes.

When cancer cells affect the outer covering of the lungs, it is quite common for fluid to collect. The fluid can build up in the space between the 2 layers. It is called a pleural effusion.

When you breathe in, the lungs expand. When you have a pleural effusion, they can't expand as far because the fluid is taking up space that the lung would otherwise expand into. The diagram below shows this.

It is possible to have the fluid drained off. But it will almost certainly build up again. You can have it drained again as you need to. Each time you do, there is a risk that you will develop an infection in the area where the needle is put in. The treatment you are about to have is to try to stop the fluid from building up in the first place. The sterile talc irritates the pleura and makes them stick together. So there is no space for the fluid to collect. It should be easier for you to breathe. If this treatment doesn't work completely the first time, you can have it repeated.

There is information in CancerHelp UK about breathing problems caused by cancer that you may find helpful. This includes more information about fluid on the lung.
