for my mom, who is having surgery tomorrow to remove a mass from her lung. they were unable to get a good biopsy of it, but it did light up as cancerous on a pet scan using whatever dye they inject in you to determine that. so basicly they will open her up, deflate the lung, remove the mass and send it to pathology while she is still on the O.R. table. if pathology confirms that the mass is cancerous as we suspect, then they will remove a lobe of her lung. so we don't know for certain what we are facing at this point. on the plus side, she is fairly young, at 60, and hopefully that will help in her recovery or the fight against cancer that is coming up. on the negative side, she has smoked for 40 plus years and that damage is already there. i appreciate y'all taking the time to remember her. God Bless!
