■ Comment from Yoichi Shiga, President of Shiga Environmental Maintenance Co., Ltd.
What Shiga Environmental Maintenance values most is creating an environment where each employee can work healthily and for a long time. While health check-ups have been conducted traditionally, many employees refrained from cancer screenings due to concerns about physical burden and pain. To solve these issues, we decided to introduce "MySignal" this time. Moving forward, through this test, we aim to become a company where as many employees as possible can work healthily and with peace of mind.

■ About "MySignal Scan"
MySignal Scan is a highly accurate cancer risk test that extracts and analyzes "microRNA," which was also the subject of the 2024 Nobel Prize in Physiology or Medicine, from urine to determine the risk of up to 10 types of cancer from Stage 1. As it is a urine test, there is no physical burden, and it can be performed by mail from home, minimizing the effort required for examination. It has been adopted as a test by over 2,000 medical institutions nationwide, and results such as early detection of lung cancer in Hokkaido have been reported.
【10 Cancer Types that can be tested】Lung, Colorectal, Pancreatic, Stomach, Esophageal, Kidney, Bladder, Prostate, Breast, Ovarian *Prostate is for men only, Breast and Ovarian are for women only

MySignal series are not medical devices. They determine risk by statistically calculating analyzed information and are not a "diagnosis" of whether one has cancer as a medical act. Even if a low risk is determined, it does not guarantee that one does not have cancer or will not get cancer in the future.
