Icaria's mission is to create a new society in which people will not lose their lives by using urine tests to provide "early, painless and accurate early diagnosis of cancer."It is known that detecting cancer early increases the survival rate 5 to 10 times and greatly improves the prognosis. However, it is not unusual for many cancers to have no subjective symptoms, and when they become aware they have progressed to a stage where treatment is impossible.
