Yes aromasin can cause cough, difficulty in breathing in 6% patients as side effects.
However, these symptoms are temporary and subside gradually over time.
Usually, your system will clear out aromasin effect within 3-4 weeks.
Since, lung CT scan is normal, there is no need for concern.
But, your pulmonary function test shows some diminished lung function.
Since there is no noticeable fibrosis of the lungs, this is not chemo related.
Herceptin also can contribute to these respiratory symptoms like aromasin.
That is why your symptoms are taking longer than usual to subside.
You should see definite improvement within next 3 months or so.
The improvement will be gradual and may take longer sometimes.
are you able to read my replies?
I understand your concern.
