Thyroid Cancer

Thyroid cancer is a malignant growth arising from the cells of the thyroid gland, located at the front of the neck. It is one of the most treatable endocrine cancers, especially when detected early. The main types include papillary thyroid cancer, follicular thyroid cancer, medullary thyroid cancer, and anaplastic thyroid cancer, each differing in behavior and prognosis. Papillary carcinoma is the most common and usually has an excellent survival rate.

Patients may present with a painless neck lump, swelling, difficulty swallowing, hoarseness of voice, or enlarged lymph nodes. Some cases are detected incidentally during imaging for other conditions. Diagnosis involves ultrasound examination, fine needle aspiration cytology (FNAC), and sometimes CT or MRI for staging. Early and accurate diagnosis is essential for effective treatment.

The primary treatment is surgical removal of the thyroid gland (thyroidectomy), often combined with lymph node removal if spread is suspected. Radioactive iodine therapy may be used after surgery to destroy remaining cancer cells. Lifelong thyroid hormone replacement therapy is required after total thyroidectomy. With proper treatment and regular follow-up, most patients achieve excellent long-term outcomes and normal quality of life.
