Worried of my wife's health

On Monday night my wife start coughing blood.. She told me in the middle of the night.. And i advise her to see the doctor... So on Tuesday, she when to see the family doctor and was told that coughing blood is a serious matter.. and doctor refer her to polyclinic for x-ray.. Her x-ray shows a lump near her heart.. but the doctor still could not confirm what it is or whether it cause her to cough blood. She had to get another x-ray on Saturday.

I was so worried about her health.. What could this lump near her heart be? Hopefully not a cancerous cell.. She was diagnose with asthma a few years ago and frequently having difficulty in breathing especially in a not well ventilated area... Maybe she do not have asthma and this lump might be that makes her breathless?

My wife just got back to the work force after a few years of being a housewife.. and we starting to move on to the next chapter of life.. and i hope her health does not move us back to the previous chapter.
