Thyroid cancer occurs when normal cells in the thyroid gland change into abnormal cells and grow not according to the body's control.

On average, each month, Department of Oncology 2, Bai Chay Hospital perform 30-40 surgeries for tumors and thyroid cancer. In early March, the doctor admitted a 50-year-old woman with no symptoms and regular physical exam to detect stage 3 thyroid cancer. The tumor is only 5 mm large but has invaded beyond the trachea, many cervical lymph nodes. The surgeon removed the entire thyroid gland and removed the cervical lymph nodes.
Thyroid cancer is divided into two groups: differentiated thyroid cancer and undifferentiated thyroid cancer. Differentiated thyroid cancer progresses slowly, with good prognosis. Undifferentiated thyroid cancer progresses rapidly, patients often come to the hospital when the tumor and lymph nodes have become widely invasive, cannot be resected, metastasized early, and have poor prognosis.
Thyroid cancer can be detected early through neck ultrasound, cytology diagnosis (FNA), CT scan or neck MRI scan, thyroid scans. The doctor accurately identifies and evaluates the exact location, number, size, nature, and invasiveness of the thyroid and cervical lymphoma with surrounding organs such as trachea, esophagus, and soft neck area.
Surgery is the main method used to bring positive therapeutic effects, especially in the early stages. Based on the type of cancer, the stage of the disease, the size of the tumor, the doctor will choose to remove the entire thyroid gland or cut a part of the thyroid gland (thyroid lobe), combined with dredging the cervical lymph nodes.
