What is the reason why thyroid cancer causes itchy throat

Thyroid cancer may cause throat itching, which may be caused by thyroid cancer invading the recurrent laryngeal nerve, radiation damage, drug side effects, etc. It is recommended that patients seek medical treatment in time and receive targeted treatment after a clear diagnosis.

1. Thyroid cancer invades the recurrent laryngeal nerve: Thyroid cancer is a malignant tumor originating from the thyroid follicular epithelium or parafollicular epithelial cells. If thyroid cancer invades the recurrent laryngeal nerve, it can cause discomfort in the throat, manifested as symptoms of itchy throat. At this time, surgery is required to remove the lesion, and auxiliary treatment measures such as radiotherapy and chemotherapy are needed;

2. Radiation damage: If the patient is undergoing iodine-131 treatment, it may cause certain damage to the surrounding tissues, causing local mucosal edema, congestion, and itchy throat. At this time, you can follow the doctor's advice to use non-steroidal anti-inflammatory drugs such as ibuprofen sustained-release capsules and celecoxib capsules to relieve symptoms;

3. Side effects of drugs: Some thyroid cancer patients may need to take drugs such as levothyroxine sodium tablets for treatment. During medication, adverse drug reactions may occur, such as nausea, vomiting and other gastrointestinal reactions, which may cause throat itching. At this time, other drugs can be replaced for treatment under the guidance of a doctor.

In addition to the above common situations, it may also be caused by improper diet and other reasons. Patients are advised to pay attention to a light diet and avoid spicy and irritating foods to avoid aggravating the discomfort symptoms.
