Thyroid Cancer

#thyroid cancer, #papillary carcinoma, #thyroidectomy, #radioactive iodine therapy, #thyroid hormone medication, #levothyroxine, #hypothyroidism, #lymph node metastasis, #thyroid ultrasound

Thyroid cancer is cancer that develops in the butterfly-shaped thyroid gland at the front of the neck. Prognosis varies greatly by type; papillary carcinoma, which accounts for more than 90% of thyroid cancers in Korea, grows slowly and responds well to treatment, so its outlook is relatively favorable. However, some rarer types have a poorer prognosis, so please be sure to decide on an accurate diagnosis and treatment through a medical specialist.

A thyroid nodule is a lump found in the thyroid gland. It is found very commonly, and most nodules are benign (not cancer). About 5% to 10% are diagnosed as thyroid cancer, so accurate testing and follow-up are important.

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.

Tongue Cancer

#tongue cancer, #oral cancer, #head and neck cancer, #squamous cell carcinoma, #smoking, #human papillomavirus, #HPV, #tongue ulcer, #glossectomy, #flap reconstruction, #nausea, #feeling like vomiting, #vomiting

Tongue cancer is a malignant tumor that develops in the tongue and accounts for about 10 to 15% of all head and neck cancers. Because early symptoms resemble those of stomatitis (mouth sores), it is often left untreated and found late. Treatment outcomes tend to be better when the cancer is detected early, so if you have a sore on the tongue that does not heal or a lump you can feel, please consult a medical specialist without delay.
