My husband, 72, saw the doc because of cough lasting much more than 3 wks. Went for two xrays on chest/lungs area which came back clear. Saw doc several times for same cough and saw another doc when own was away. Was examined and told to see own doc which he did. At that point he was refered to specialist who sent him across corridor for cameras and found to have cancer growth in two areas of the oesophagus at lower point as it turned into stomach. I suspect 2nd doc felt something and advised his own doctor. I'd really like to know why his doctor, in my opinion, only thought coughs came from lung irritation. If she had looked further perhaps the growth could have been found earlier and my husband would still be here.
