John is your patient.
He’s pretty worried about having an enlarged thyroid gland.
Your job is to recommend John a treatment plan for dealing with his condition.

Chemotherapy• John had very nasty side
effects from the chemotherapy. He lost his hair and felt very ill.
• 3 years later John’s cancer came back. The next time he didn’t pull through.

Surgery
• John did not feel well after his surgery, but he soon recovered and all of the cancer was removed.
• John’s voice box was damaged and he has difficulty speaking because of his operation.

Radiation with gamma-rays
• John felt pretty sick, after the treatment. His throat was very sore, but at least the ice cream was soothing.
• John had to go back for several treatments and his cancer went into regression. He is still monitored regularly.

Radiation with Beta Particles
• John took Iodine tablets. He was not allowed to see his family and friends for a few days.
• The treatment cleared up John’s cancer, but he still has to be monitored just in case.
