Kidney cancer is a malignant tumor that develops in the kidney. There are almost no symptoms in the early stages, so it is difficult to notice on your own, and in most cases it is found incidentally during a health checkup. Even without symptoms, it is important to detect it early through regular health checkups. If an abnormal finding is detected or you have any concerns, please be sure to consult a medical specialist.

Liver Transplantation

Liver transplantation is an operation that replaces a liver that has lost its function with a healthy liver, and it is one of the treatment options for several serious liver diseases, such as liver failure caused by cirrhosis and liver cancer. Since it was first performed in Korea in 1988, advances in technology and medication have led to more than 1,500 transplants a year at present, and the overall surgical success rate is reported to be about 90 to 95%. Liver transplantation is an important decision for both the recipient and the donor, so please discuss it thoroughly with your treating physician before making a decision.

Lung Cancer

Lung cancer is a malignant tumor that develops in the bronchi or lungs and is the leading cause of cancer death in Korea. It often causes no symptoms in its early stages, so regular screening is important for high-risk groups. Smoking is the leading cause, and quitting smoking is the most effective way to help prevent it.

Osteoporosis

#osteoporosis, #bone density, #compression fracture, #menopause, #calcium, #vitamin D, #bisphosphonates, #fall prevention, #vertebral fracture, #femoral fracture, #dry cough, #persistent cough, #cough that won't stop

Osteoporosis is a condition in which bones become weaker and can break easily even from a minor impact. There are often no symptoms, and it is frequently discovered only after a fracture occurs. The risk is higher in postmenopausal women and older adults, so regular bone density testing and preventive lifestyle habits are important. Please be sure to discuss treatment options with a medical specialist.

Osteoporosis in Patients with Asthma

#asthma, #osteoporosis, #steroids, #vertebral compression fracture, #bone density, #calcium, #vitamin D, #dry cough, #persistent cough, #cough that won't stop

Long-term use of steroid medications used to treat severe or chronic asthma can lead to osteoporosis. When osteoporosis becomes severe, a vertebral compression fracture can occur even with minor impact, so caution is needed. Please have regular bone density testing and follow up with a medical specialist.

#parainfluenza, #croup, #laryngotracheobronchitis, #children, #infants, #barking cough, #respiratory infection, #dry cough, #persistent cough, #cough that won't stop

Parainfluenza virus causes acute respiratory illness in infants and young children. It is a major cause of croup (laryngotracheobronchitis), which can produce a harsh, barking cough or hoarseness.

Pneumonia in older adults generally refers to pneumonia that occurs at age 65 or older. Pneumonia is inflammation of the lungs caused by infection with bacteria, viruses, or other organisms. More than 50% of people with pneumonia and more than 90% of people who die of pneumonia are aged 65 or older. In older adults, symptoms are often not obvious, so diagnosis is easily delayed. If you have suspected symptoms, please consult a pulmonology and allergy specialist immediately.

Pneumothorax is a condition in which air collects between the lung and the chest cavity (the space inside the chest). The chest cavity is the space that surrounds the lungs. It mainly occurs on one side of the chest, and chest pain and difficulty breathing are the typical symptoms. If you suspect symptoms, please consult a medical specialist.

Radiation Therapy

#radiation therapy, #anticancer therapy, #cancer treatment, #lack of energy, #lethargy, #persistent fatigue, #dry cough, #frequent mild cough, #persistent cough, #loose stool, #watery diarrhea, #frequent bowel movements

Radiation therapy is a treatment that uses high-energy radiation to damage the DNA of cancer cells, which stops their growth and ultimately destroys them. Some normal cells are also damaged, but they usually recover more quickly than cancer cells and may return to normal function after treatment ends.

Tobacco smoke contains thousands of chemicals, including carcinogens (substances that can cause cancer), and long exposure in an enclosed space can be harmful even to nonsmokers. If you are concerned about secondhand smoke, please consult a medical specialist.
