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.

Thyroid Nodule

#thyroid nodule, #thyroid, #thyroid ultrasound, #fine-needle aspiration biopsy, #Bethesda classification, #atypical, #thyroid cancer

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.

Treatment and Chemotherapy for Lung Cancer

#lung cancer, #chemotherapy, #targeted therapy, #immunotherapy, #cytotoxic chemotherapy, #loose stools, #watery diarrhea, #frequent bowel movements

Treatment for lung cancer — surgery or chemotherapy — is determined by the appearance of the cancer cells and how far the disease has spread. Please do not delay treatment out of fear of side effects; be sure to discuss your options with a pulmonology specialist to find a safe treatment approach suited to you.

Urinary Incontinence in Men

#urinary incontinence, #male urinary incontinence, #stress urinary incontinence, #urge urinary incontinence, #prostate surgery, #Kegel exercises, #artificial urinary sphincter, #urinary frequency, #overactive bladder, #dry cough, #persistent minor cough, #cough that will not stop, #frequent urination, #going to the bathroom often

Urinary incontinence does not occur only in women; it also occurs in men, and the number of men with urinary incontinence is increasing with population aging and a rise in prostate disease. It often occurs after prostate surgery or because of benign prostatic hyperplasia (enlarged prostate), diabetes, and similar conditions. It can be managed with proper care, including Kegel exercises, drug treatment, and, when necessary, surgical treatment, so please consult a medical specialist.

Vertebral Compression Fracture

#vertebral fracture, #compression fracture, #spine, #back pain, #osteoporosis, #fall, #fracture in older adults, #bone cement, #dry cough, #persistent cough, #cough that won't stop

A vertebral compression fracture occurs when the impact of a fall onto the buttocks is transmitted to the spine, although in severe osteoporosis a vertebra can also collapse gradually without a significant impact. Severe back pain, including pain with coughing, is a main symptom. In older adults, prolonged bed rest during recovery can lead to complications such as pneumonia or pressure sores, so caution is needed. If you have back pain after a fall, please consult an orthopedic specialist.
