The radiation Dr. is sending him to a pulmonologist....I looked up all the terms...it simply means he has a tumor on his tracheo which is likely causing him to spit up the blood....why don't they just say that on the reports. According to the Dr. the sweats are caused by cancer...so we both get a laugh out of it to see who is going to wake up first...him from sweating from the cancer or me from sweating from hot flashes!!! My washing machine really got a work out this weekend!
