Suffering from mild pneumonia. X-ray showed a shadow on right hilar. Can a shadow or mass be pneumonia in this region?

HI, My husband has had amild pneumonia since 21st July were his first symptoms - aching muslces and joints, ore throat, cough, headache, fever, chills, a week later had a mild small ras on his inner elbows. 2 days into his symptoms on Monday 23rd JUly he went to the dcotro who suspcted pneumonia and sent him for an xray which showed a shadow on his right hilar. The doctor was very irresponsible and said if my husband was a smoker (he is 41 and a non-smoker but his dad was a heavy smoker and he grew up around it) he thought it would be lung cancer. we have been worried sick ever since. He has since recovered - in about 9 days all he has now is a bit of a cough left and some mild discomfort on his right side if he lies in certain positions. The doctor has said pneumonia doesn't occur in the hilar region - is this true? He is going for a ct scan next week and he has some blood tested but the doctor has told us nothing about it. I am so annoyed with our doctor. He has also stated on the ct scan form that it is a hilar mass but said to us it's a shadow. can a shadow or mass be pneumonia in this region? Is it atypical (walking) pneumonia? My 4 year old daughter has had similar symptoms for 3 weeks. Both have been on antibiotics and made a recovery. Any help would be appreciated, many thanks,
