Thyroid cancer - papillary carcinoma

Alternative Names

Treatment

There are three types of thyroid cancer treatment:

• Surgery
• Radioactive iodine
• Medication

Surgery is done to remove as much of the cancer as possible. The bigger the lump, the more of the thyroid gland must be removed. Frequently, the entire gland is taken out.

After the surgery, most (but not all) patients receive radioactive iodine, which is usually taken by mouth. This substance kills any remaining thyroid tissue. It also helps make medical images more clear, so doctors can see if there is any additional cancer.

If surgery is not an option, external radiation therapy can be useful.

After surgery, the patient will need to take medication called levothyroxine sodium for the rest of their life. This replaces the hormone that the thyroid would normally make.

The patient will need a blood test every 3 to 6 months to check thyroid levels, and an imaging test called a radioactive iodine (I-131) uptake scan once a year.

Outlook (Prognosis)

The survival rate for papillary thyroid cancer is excellent. More than 95% of adults with such cancer survive at least 10 years. The prognosis is better for patients younger than 40 and for those with smaller tumors.

The following factors may decrease the survival rate:

• Age over 40
• Cancer has spread to distant parts of the body
• Cancer has spread to soft tissue
• Large tumor

Possible Complications

Complications include:

• Accidental removal of the parathyroid gland, which helps regulate blood calcium levels
• Damage to a nerve that controls the vocal cords
• Spreading of cancer to lymph nodes (rare)
• Spreading of cancer to other sites (metastasis)

When to Contact a Medical Professional

Call your health care provider if you have a lump in your neck.
