John and Radha were classmates since childhood.


John and Radha were classmates since childhood. When Radha became eleven years old, she developed a little swelling in her neck. She visited the

doctor who started medication for her.

After a few years, John also developed a slight protrusion on his throat. He got worried and went to the doctor. But, the doctor assured him

that it was a normal feature in boys while they are growing up. Can you think of any reasons for the difference in diagnoses?


The swelling on the neck of Radha may have been because of goitre, a condition during which the thyroid gland produces insufficient quantity of 

thyroxine. However, the protrusion in John’s throat would be due to Adam’s apple (bulge) that is a result of growth of voice box in adolescent boys.
