Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of cancer is less.
Possibility of viral bronchitis is more. Viral infection is causing
sore throat and bronchitis is causing cough, chest congestion etc.
So better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. Chest x ray
3. PFT (pulmonary function test).
Chest x ray is must to rule out
lung infection and cancer. If chest x ray is normal then no need to worry for lung cancer.
PFT will not only diagnose bronchitis but it will also tell you about severity of the disease and treatment is based on severity only.
You will need inhaled
bronchodilator and inhaled
corticosteroids (ICS).
Don't worry, you will be alright.
Don't worry about cancer.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
