Cervical instability (atlantoaxial instability) is a condition in which the connection between the first and second neck bones (cervical vertebrae) becomes loose and allows excessive movement. Mild cases may cause no symptoms, but as it progresses it can compress the spinal cord and lead to serious nerve damage. It is relatively common in patients with rheumatoid arthritis. Please be sure to decide on an accurate diagnosis and treatment approach through a medical specialist.2026-06-26

Thyroid Nodules and Thyroid Cancer
#thyroid cancer, #thyroid nodule, #thyroid ultrasound, #fine-needle aspiration cytology, #papillary carcinoma, #radioactive iodine, #thyroid surgery, #weakness in arms and legs, #difficulty moving one side of the body
Thyroid cancer is a malignant tumor that develops in the thyroid gland, a butterfly-shaped endocrine organ at the front of the neck that secretes the thyroid hormones that regulate the body's metabolism. Thyroid nodules (lumps) are very common, and a portion of them are found to be cancer, so early detection through ultrasound and cytology is important. If you can feel a lump in your neck or have symptoms such as voice changes, please consult an ENT specialist.2026-06-26
