talc

talc
A mineral, usually used in a powdered form. In cancer treatment, sterile talc is used to prevent pleural effusions (an abnormal collection of fluid in the space between the lungs and the chest wall). Talc is inserted into the space, causing it to close up, so fluid cannot collect there. Also called sterile talc powder.
