Thyroid Diseases
Follicular Thyroid Cancer
Follicular carcinoma is the second most common thyroid cancer. The diagnosis is often confirmed by examining the tissue removed at surgery, and surgery is the mainstay of treatment.
What is thyroid cancer?
The thyroid is a butterfly-shaped gland in the middle of the neck, just below the Adam's apple. Its hormones regulate heart rate, blood pressure, body temperature and weight. Thyroid cancer begins in the cells of this gland.
In most cases the cause is not clear. It is more common in women; high radiation exposure and certain inherited syndromes raise the risk. One reassuring fact: most thyroid cancers respond very well to treatment, and in the majority of cases the disease does not affect life expectancy.
Treatment options
Treatment depends on the type and stage of the cancer, your general health and your preferences. For most patients surgery is the first step: sometimes the whole gland is removed (thyroidectomy), and in some very small cancers only one lobe. Where needed, the neck lymph nodes are assessed in the same operation.
If the whole gland is removed, thyroid hormone is replaced with daily medication, checked with blood tests every few months at first and then yearly. Some patients also receive radioactive iodine after surgery to clear any remaining tissue. Which of these steps applies to you is explained at the visit, in plain language.

Frequently asked questions
Like any operation it carries bleeding and infection risks. Risks specific to the thyroid are low calcium, if the parathyroid glands are affected, and voice change, if the vocal-cord nerves are injured. Protecting these structures is the operation's priority, and your personal risk is discussed beforehand.
