New procedure shrinks giant goiters without surgery

This study tests a new, less invasive treatment for large thyroid nodules (giant nodular goiter) that cause discomfort or breathing problems. The procedure uses a tiny tube to deliver a chemotherapy drug (bleomycin) directly into the nodule's blood supply, blocking it and shrinking the growth. The study will enroll 30 people to see how well this approach reduces nodule size and improves symptoms.
