Thyroid Tumor
What Is a Thyroid Tumor?
Various tumorous lesions can arise in the thyroid gland, including:
- Benign nodules
- Thyroid cancer
and other types of lesions.
In particular, benign nodules are sometimes discovered as a result of swelling in the neck, a feeling of pressure, cosmetic concerns, or other such signs.
Standard Treatments
Treatments for thyroid tumors include observation, surgery, drug therapy, and other approaches.
The treatment plan is determined according to the type, size, and degree of malignancy of the lesion.
Radiofrequency Ablation (RFA) for the Thyroid
Radiofrequency ablation (RFA) for the thyroid is a minimally invasive treatment in which a needle is inserted through the skin and the lesion is treated with heat. Although it is currently not covered by health insurance in Japan, its efficacy and safety have been reported both in Japan and overseas.
At our clinic, in cooperation with Showa University Northern Yokohama Hospital, specialists in needle puncture procedures perform radiofrequency treatment using ultrasound and CT with careful attention to safety.

Indications for Thyroid Radiofrequency Ablation
In general, the following are considered indications:
- Benign thyroid nodules
- Low-risk papillary microcarcinoma
and similar conditions.
Depending on the patient's condition, it may also be considered for:
- Postoperative recurrence
- Lymph node metastasis
and other situations.
The actual indication is determined comprehensively, taking into account the nature and location of the lesion as well as the patient's overall condition.
Effectiveness of Thyroid Radiofrequency Ablation
Radiofrequency ablation is a minimally invasive treatment performed by inserting a needle through the skin, so it can be carried out without leaving a large scar. It is therefore one of the minimally invasive treatment options for those who wish to avoid a scar on the neck or who place importance on cosmetic outcomes. Immediately after the procedure, temporary swelling or discomfort in the neck may occur, but in most cases this improves over time. The lesion then gradually shrinks over several months. After treatment, we monitor progress regularly with ultrasound, CT, and other examinations.

Possible Complications
We take the utmost care to ensure the safety of treatment; however, the main complications include the following.
Recurrent laryngeal nerve palsy
If heat affects the nerve that moves the vocal cords (the recurrent laryngeal nerve), symptoms such as hoarseness or difficulty producing the voice may occur. Most cases are temporary, but in rare cases the symptoms may persist for a long period.
Burns
Heat transmitted to the skin or surrounding tissue may cause mild burns, pain, or swelling. Most cases are mild and improve with observation or topical treatment.
Bleeding
Bleeding may occur at the puncture site or around the thyroid. In most cases it is absorbed naturally, but if the bleeding is significant, additional procedures or follow-up observation may be required.
Our response
During treatment, we proceed carefully while checking the surrounding tissue with ultrasound to prevent complications. After treatment, we also monitor the patient's condition closely and take appropriate measures as needed.
Our Clinic's Approach to Care
In treating thyroid tumors, it is important to consider not only curative outcomes but also the physical burden on the patient and cosmetic concerns.
At our clinic, we propose appropriate treatment options, including surgery, observation, and RFA, based on each patient's condition and wishes.
If you are unsure about minimally invasive treatment options, please feel free to consult us.
