Hi,
Noted your history about
sore throat but swallowing the sputum, but in the morning your could find solid red stuff in the phlegm, Doctor diagnosed as
bronchitis and gave the medication, you are worried that this is not cancer and wants to know more.
Cancer is usually symptom less in the initial stage and usually has loss of appetite and weight
chronic cough with or without blood in the phlegm.
This can be diagnosed by the following:
First of all get the initial treatment for control of the symptoms.
If there is no relief let the investigations be started with simple X-ray of chest and tests of blood and sputum/phlegm.
If the condition does not improve then you can take an opinion of a Pulmonologist for PFT,
CT scan of chest and other specific investigations to get a proper cause.
Once the cause is found the treatment can be specific and effective.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT and General Surgeon
