Side effects of treatment
The side effects of surgery for thyroid cancer are usually mild and last a couple of days. Your doctor will talk to you about medicine you can take if you are having pain. You will likely need to take thyroid hormone medicine for the rest of your life to replace the hormones that your body no longer makes.
The most important side effect of radioactive iodine therapy (RAI) is that you will become radioactive for a period of time. Your doctor will give you written instructions to follow to prevent exposing others to radiation. For more information, see Radioactive Iodine.
Thyroid hormone therapy rarely causes side effects when you have the right dose. Too much or too little thyroid hormone can cause side effects.
Taking high doses of thyroid hormone may cause a rapid or irregular heartbeat. High doses taken over time may also cause weakness in your bones (osteoporosis).
Home treatment may help you manage your side effects.
Treatment if the condition gets worse
Thyroid cancer may come back (recur). If thyroid cancer does recur, it may be found during a physical exam, on an ultrasound, or as a result of increasing thyroglobulin levels. Unlike other types of recurrent cancer, recurrent thyroid cancer is often cured, especially if it has spread only to the lymph nodes in the neck.
Recurrent thyroid cancer or thyroid cancer that has spread (metastasized) to other parts of the body may be treated with surgery, radioactive iodine, radiation, or chemotherapy.
Your doctor may talk to you about being in a clinical trial. For some people with thyroid cancer, taking part in a clinical trial may be the best treatment choice. Clinical trials for thyroid cancer are looking at targeted therapy with tyrosine kinase inhibitors.
Palliative care is a kind of care for people who have a serious illness. It's different from care to cure your illness. Its goal is to improve your quality of life-not just in your body but also in your mind and spirit.
You can have palliative care along with treatment to cure your illness. You can also have it if treatment to cure your illness no longer seems like a good choice.
Palliative care providers will work to help control pain or side effects. They may help you decide what treatment you want or don't want. And they can help your loved ones understand how to support you.
If you're interested in palliative care, talk to your doctor.
