John visited the doctor with symptoms including large hands and feet. Test results showed low hormone levels and high growth hormone levels. Imaging showed no issues with his knee but it was being damaged. He was diagnosed with a pituitary tumor causing the hormone imbalances. Irradiation was used to destroy the tumor. Follow up showed the tumor was destroyed and hormone levels stabilized, though replacement therapy was needed. John also had physical deformities treated, including jaw surgery for a protruding jaw. Further testing confirmed a diagnosis of acromegaly due to excessive growth hormone levels.
