hello doctor, I am a 35 years old, mom of a 2.5 yr old kid. My height is 5 2 and weight is 75 kgs. I am hypo-thyroid for the last 10 years. Lately, I am experiencing difficulty swallowing(not while eating), u know it is after every 2 minutes while breathing. This things keeps on appearing almost every 20-25 days, remains for 4-5 days. I have a friend who has been operated for thyroid cancer. And that s what worries me. Do you think this is a symptom of thyroid cancer? Please advise me.
