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.

Burnout and Stress Management

#burnout, #stress, #exhaustion, #sleep, #mindfulness, #goal management, #workplace, #mental health, #lack of energy, #lethargy, #persistent fatigue

Burnout (exhaustion) is not simply a matter of fatigue or lack of willpower. It is a state in which accumulated chronic stress is thought to reduce the brain's ability to regulate itself. Rather than simply 'enduring' it, management aimed at helping the brain recover is needed. It is important to recognize the early signs of burnout and find your own ways to manage stress.

Cardiac arrest is a life-threatening emergency in which the heart stops and cannot pump blood to the body. Calling 119, prompt cardiopulmonary resuscitation (CPR) by bystanders, and treatment by an emergency medicine specialist are key to saving the patient's life.

Cerebral Aneurysm

A cerebral aneurysm is a condition in which the wall of a blood vessel in the brain becomes abnormally thin and bulges outward. Before it ruptures, it usually causes no symptoms and is sometimes found by chance during a health checkup. Because a rupture can become a life-threatening emergency, people with risk factors are advised to talk with their doctor about regular screening. If a health checkup shows an abnormal finding, please consult a neurosurgery specialist, and if a sudden, severe headache occurs, seek immediate medical attention at an emergency room.
