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. If a breast screening shows an abnormal result, or if you notice a lump or a change in the skin, please see a medical specialist.

Deep Vein Thrombosis (DVT)

#deep vein thrombosis, #DVT, #blood clot, #pulmonary embolism, #leg swelling, #economy class syndrome, #dry cough, #persistent cough, #cough that won't stop

Deep vein thrombosis is a condition in which a blood clot (a lump formed when blood coagulates) develops in a deep vein of the leg and blocks the vessel. Leg swelling and pain are the main symptoms, and if the clot travels to the lungs, a dangerous complication called pulmonary embolism can occur. If you suspect symptoms, please consult a medical specialist right away.

Dementia Prevention

#dementia prevention, #three do's and three don'ts, #depression, #stress, #aerobic exercise

Dementia does not appear suddenly; it results from harmful changes that accumulate in the brain over a long period of time. Building good habits in daily life from a young age is the best way to help prevent it. Making an ongoing effort to protect one's own health is especially important. If you or a loved one notices signs of memory loss or other cognitive changes, please consult a medical specialist.

Early Detection and Management of Liver Disease

#liver disease, #liver cancer, #cirrhosis, #hepatitis B, #hepatitis C, #fatty liver, #nonalcoholic steatohepatitis, #hepatectomy, #minimally invasive surgery, #early screening, #alcohol abstinence, #lack of energy, #listlessness, #persistent tiredness, #nausea, #feeling about to vomit, #vomiting

The liver is a 'silent organ.' Even as damage progresses, there are no obvious symptoms in the early stage, so fatigue, loss of appetite, and weight loss are often dismissed as minor, and the disease is often discovered only after it has progressed to cirrhosis or liver cancer. Regular checkups are the most important way to protect liver health.

Early-Onset Dementia (Young-Onset Dementia)

#early-onset dementia, #young-onset dementia, #alcohol-related dementia, #lifestyle diseases, #vascular dementia

Dementia is not a disease that affects only older adults. Dementia that develops at a relatively young age, between 45 and 65, is called early-onset (presenile) dementia. Because it tends to progress faster than dementia in older adults, please consult a medical specialist without delay if symptoms occur.

Endometrial Cancer

#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

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.

Heart failure is a condition in which the heart cannot supply as much blood as the body needs. With appropriate treatment and management, it is possible to maintain daily life, but if left untreated, symptoms such as shortness of breath and swelling can worsen. If you have risk factors such as high blood pressure, diabetes mellitus, or obesity, please see a medical specialist regularly.

High-Risk Pregnancy

#high-risk pregnancy, #advanced maternal age pregnancy, #gestational hypertension, #preeclampsia, #gestational diabetes mellitus, #preterm birth, #preterm labor, #obstetrics and gynecology, #anxious feeling in the chest, #restlessness, #worrying for no reason

A high-risk pregnancy is a pregnancy with a higher chance than usual of adversely affecting the mother and the fetus. Advanced maternal age (35 or older) is one risk factor for a high-risk pregnancy. Recognizing your own risk factors and following your medical team's guidance can help lead to a good outcome.

Hypertension (High Blood Pressure)

#hypertension, #blood pressure, #blood pressure medication, #sodium, #arteriosclerosis, #antihypertensive drugs, #essential hypertension, #headache, #a splitting headache, #migraine, #back-of-head pain

Hypertension is a condition in which blood pressure, the force exerted on the walls of the blood vessels when the heart pumps out blood, stays persistently high; it is classified as a systolic blood pressure of 140 mmHg or higher or a diastolic blood pressure of 90 mmHg or higher. Hypertension often causes no symptoms, so it is called the "silent killer." If left untreated, it can lead to serious complications such as stroke, heart disease, and kidney disease, so evaluation by a medical specialist and steady management are needed.
