#basal cell carcinoma, #skin cancer, #ultraviolet rays, #skin, #tumor, #mole

Basal cell carcinoma is the most common skin cancer. It mainly occurs in areas with long-term ultraviolet exposure, and the outlook is generally favorable when it is completely removed by surgery. If you have an area of skin that has not healed for a long time or keeps changing, please be sure to consult a dermatologist.

Biliary Tract Cancer

#biliary tract cancer, #cholangiocarcinoma, #gallbladder cancer, #jaundice, #liver fluke, #bile duct stones, #painless jaundice

Biliary tract cancer is a malignant tumor that develops in the bile ducts, through which bile flows, or in the gallbladder. It mainly occurs in people in their 60s and older, and it is often found when jaundice appears after a period without symptoms. The earlier it is detected, the better the outlook for treatment, so if you have risk factors, please have regular checkups.

Blood Cancer

#blood cancer, #leukemia, #multiple myeloma, #platelets, #bone marrow, #anemia, #chemotherapy, #hematopoietic stem cell transplantation

Blood cancer refers to cancer that arises in the bone marrow, the organ responsible for producing blood cells. The bone marrow makes three types of blood cells: white blood cells, red blood cells, and platelets. When the bone marrow malfunctions, abnormalities in the number, shape, or function of these cells can cause a variety of symptoms. Frequent nosebleeds or easy bruising can occur, but these symptoms do not necessarily mean a person has blood cancer. If abnormal results appear on a blood test, please consult a hematology-oncology specialist.

Breast cancer is a malignant tumor that develops in breast tissue, and it is one of the more common cancers in women. Surgical and reconstruction techniques continue to advance, and outcomes are generally good when the cancer is found early.

#endometrial cancer, #uterine cancer, #abnormal bleeding, #menopause, #obesity, #endometrium, #gynecologic cancer

Endometrial cancer develops in the endometrium, the tissue lining the inside of the uterus. It is a gynecologic cancer that is becoming increasingly common in Korea. In its early stages, it can cause symptoms such as abnormal vaginal bleeding, and when detected early, the outlook tends to be relatively favorable. If you have abnormal bleeding, please be sure to consult a medical specialist.

Esophageal cancer is a malignant tumor that develops in the esophagus. It can be difficult to detect in the early stages, and the earlier it is found, the better the treatment outcomes tend to be. Reducing risk factors and getting regular screening are important, and if you have any unusual symptoms, please consult a medical specialist.

The gallbladder is a small pouch that temporarily stores the digestive fluid (bile) made in the liver. Gallbladder cancer, a malignant tumor that develops there, causes no obvious symptoms until the disease is quite advanced, which makes early detection very difficult. If you have persistent indigestion or abdominal pain, please do not dismiss it on your own; be sure to consult a medical specialist for an examination and detailed tests.

Head and Neck Cancer

Head and neck cancer is a general term for malignant tumors that develop in the head and neck region, including the larynx, oral cavity, oropharynx, hypopharynx, nasal cavity, and nasopharynx. Because this area is involved in essential everyday functions such as breathing, swallowing, and speaking, treatment can be challenging. If you have a voice change lasting more than 6 weeks, a mouth sore that doesn't heal after 3 weeks, or a lump in the neck, please see an ENT (ear, nose, and throat) specialist.

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.

Kidney transplantation is a surgery that transplants a healthy kidney into a patient with end-stage kidney failure, whose kidneys can no longer function properly. If the transplanted kidney functions normally, the patient may be freed from dialysis (a treatment that filters waste products from the blood using a machine), which can greatly improve quality of life. Ongoing care after surgery is very important, and please be sure to consult a medical specialist about anything related to transplantation.

Leukemia is a malignant tumor that arises from immature blood cells in the bone marrow. It is classified as acute or chronic, and as myeloid or lymphoid depending on the type of cell involved. Unlike in the past, advances in medicine, including targeted therapy, have expanded the treatment options. Please discuss the diagnosis and treatment plan thoroughly with a hematology-oncology 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.
