answered 28 Mar 2026John and Radha were classmates since childhood. When Radha became eleven years old, she developed a little swelling on 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?
A.VERIFIED ANSWERfact-checked by tutors
Goitre may be reason behind swelling of Radha’s neck Goitre is the condition of the thyroid gland during which the gland produces insufficient quantity of thyroxine. In case of JOHN’s swelling of neck may be because of Adam’s apple which is the result of growth of voice box in adolescent boys.
