Hematopoietic stem cell transplantation (HSCT) is a treatment that transplants hematopoietic stem cells, the cells that give rise to white blood cells, red blood cells, and platelets. It was previously known as bone marrow transplantation, but the name changed once it became possible to collect these cells from peripheral blood as well. It is mainly used to treat blood-related malignancies, and both the treatment process and follow-up care afterward are important.

Kidney Transplant Process

#kidney transplantation, #kidney transplant, #living-donor kidney transplantation, #deceased-donor kidney transplantation, #immunosuppressants, #rejection, #end-stage kidney failure, #KONOS, #organ transplantation, #double vision, #overlapping images

Kidney transplantation is a surgery that transplants a healthy kidney into the body to replace a kidney that has lost its function. Unlike dialysis, it can restore most of the kidney's various functions (removing waste products, regulating electrolytes, secreting hormones that stimulate blood cell production, and others), which makes it one of the main treatment options for end-stage kidney failure. Whether and how to have a transplant depends on each patient's health condition, so please be sure to decide through consultation with a medical specialist.

Liver Cancer

Liver cancer is a malignant tumor that develops in the liver, which is responsible for detoxification and nutrition in the body. The liver is called the 'silent organ' because there is no particular pain even when the disease becomes advanced. By the time symptoms appear, the disease has often already progressed considerably, so please do not judge on your own; be sure to have regular checkups and consult a medical specialist.

Liver Cancer: Key Questions

#liver cancer, #hepatocellular carcinoma, #cirrhosis, #hepatitis B, #hepatitis C, #hepatectomy, #liver transplantation, #Milan criteria, #ascites, #jaundice, #transarterial chemoembolization (TACE)

Liver cancer (hepatocellular carcinoma) is a malignant tumor that develops from the cells that make up the liver. Because there are almost no symptoms in the early stage, it is often found incidentally during health checkups. Regular checkups are especially important for people with chronic liver disease caused by hepatitis B, hepatitis C, or alcohol-related liver disease. The treatment method and prognosis differ depending on each patient's condition, so please consult a medical specialist before making any decisions.

Multidrug-resistant organisms are bacteria that have developed resistance to several types of antibiotics. They are also called 'superbugs.' Misuse and overuse of antibiotics are the main cause, and infection with them can be very hard to treat. Please take antibiotics only as prescribed by a doctor and for the prescribed length of time. If you have questions about antibiotic use, please consult your doctor.

If you have suspected symptoms, please consult a pulmonology and allergy specialist immediately.
