Dear friend, welcome to Healthcaremagic!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
He seems to have bad lungs from long standing COPD
and history of cancer. Oral thrush
indicates poor immunity.
Yeast infection can not be separately seen on an Xray. It shows as pneumonia
or infiltrates or rarely a fungal ball in cavities.
It is diagnosed on staining and culture.
Since he has not grown anything on culture, we can not reliably tell if he has a fungal lung infection
But such a bad combination may make it a good possibility though cultures are negative.
Thrush should be treated. If is so breathless, may need hospitalized care again and re-work-up.
I would put him on anti-fungals.
I hope to have answered your query satisfactorily. I would be glad to answer any further queries. Take care and please keep me informed of your progress at http://bit.ly/Dr-Prasad-Akole
