Gallbladder Cancer

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.

A gastrointestinal stricture is a narrowing of a passage in the digestive tract, such as the esophagus, stomach, or intestine.

Depending on the cause and location, it is managed with endoscopic treatment or surgery. If you have these symptoms, please be sure to see a medical specialist.

Glaucoma

Glaucoma is a disease in which the optic nerve inside the eye is gradually damaged by high intraocular pressure or other factors, causing the visual field to narrow progressively. There are almost no symptoms in the early stage, so detection can be delayed, and rather than a cure, lifelong consistent management is important. Detecting it early through regular checkups and starting treatment is the best way to help prevent blindness.
