On the day of the event, Dr. Ryo Nakagawa, Chairman of Omiya City Clinic, one of the leading health screening facilities in the Kanto region, and professional soccer player and investor Keisuke Honda were invited to speak about the importance of 'early detection' of cancer from their respective perspectives. Additionally, Craif CTO Hiroki Ichikawa shared the background of opening the miSignal Shop and future prospects.

■ Special Lecture: 'The Importance of Cancer Screening'

Dr. Ryo Nakagawa spoke about the current state of cancer screening and the importance of early detection. From a specialist's point of view, he discussed the psychological barriers that prevent people from undergoing screenings, the importance of widely communicating the necessity of screenings, and the significance of awareness campaigns that encourage hesitant individuals to take the first step.

*The following is an excerpt.

Early Detection Increases Treatment Possibilities

'For many cancers, early detection is extremely important in increasing the chances of successful treatment. To achieve this, it is crucial to undergo regular cancer screenings. However, in reality, the hurdles to getting screened are high due to various reasons such as "I don't want to do it because I'm anxious" or "I don't have time."'

'The number one reason people do not get cancer screenings is "lack of time." Also, a very common answer is "I am confident in my health, so I don't need it." This "mental hurdle" is a major factor hindering access to medical care.'

A Place to Alleviate Anxiety Before Visiting a Medical Institution is Needed

'It is important to make regular cancer screenings a personal matter. To that end, I believe it is essential to alleviate anxiety before visiting a medical institution and to widely communicate the necessity of screenings. At our facility, we value creating an environment where people coming for comprehensive health checkups can feel at ease. The miSignal Shop is also a very sophisticated space where anyone who is even slightly concerned about cancer or their health can easily drop by. I feel it is very meaningful for such places to function as an entry point to visiting medical institutions.'

Breaking Down and Delivering the Latest Technology is Also the Role of Medical Professionals

'The microRNA technology, which detects components leaking from cancer into urine or components indicating characteristics of a cancer-prone constitution, is an excellent technology. When such simple and new technologies emerge, it is also our role as medical professionals to break down what they are and provide them to everyone.'

■ Special Talk: Approach to Health and Prevention

Keisuke Honda led a session where participants thought about 'early detection' as a personal matter, incorporating quizzes about cancer survival rates and treatment costs. Drawing on his experience as an athlete, he also spoke about his own approach to health and prevention.

*The following is an excerpt.

The Importance of 'Prevention' from an Athlete's Perspective

'Athletes pay much more attention to "prevention" than the general public. In our case, it's the prevention of "injuries," but since an injury can ruin all our efforts, we take every possible measure, such as hiring exclusive chefs and trainers. This difference in prevention makes a huge difference in whether you can play for a long time and be successful. Cancer, which is today's theme, is different from injuries; it is life-threatening.

In the case of lung cancer, if detected early, the 5-year survival rate increases tenfold. The cost of treatment also changes by nearly 10 million yen. There is no reason not to take proper care. It's too late once you get sick.'

'I was shocked to learn that pancreatic cancer progresses very quickly, and it is common for it to reach the terminal stage in just a quarter of a year. A "once-a-year health checkup" alone might not be enough. Currently, in addition to my annual health checkup, I use miSignal to check my health every six months.'

Facing Health as a Personal Matter Together with Family

'Please take today's talk about the importance of early cancer detection home and share it with your family. I would be happy if you could think of it as your own issue and face your health seriously.'

■ Introduction to miSignal Shop

Craif CTO Ichikawa introduced the 'miSignal Shop', the first physical store for miSignal.

Aiming to Eliminate Psychological Hurdles to Testing in a Place for Casual In-Person Consultation

'The fact that "1 in 2 people will get cancer" is a reality we cannot look away from. While the advancement of treatment is important, early detection is above all crucial. Early detection not only increases survival rates but also has many benefits, such as reducing medical expenses and shortening the number of hospital visits. I want people to fully understand this.'

'We have now opened the first physical store for miSignal, the "miSignal Shop." It is a place where you can consult about questions and concerns regarding early cancer detection and what kind of test miSignal is. Based on a track record of over 12,000 consultations, staff with specialized knowledge will assist you.'

Becoming a Place That Triggers People to Face Cancer

'I hope this becomes a place where people who are curious but tend to put it off, or who find it hard to take the first step, can casually drop by and be prompted to face cancer. Our vision at Craif is "Realizing a society where people live out their natural lifespans." We will continue to work towards realizing this.'

■ About 'miSignal Scan'

'miSignal Scan' is a test that extracts microRNA from urine and analyzes it with AI to evaluate the risk of 10 types of cancer*, including pancreatic cancer, by cancer type, starting from Stage 1. By simply collecting urine, it is possible to test without any burden on the body.

For details, please visit the website: https://misignal.jp/

'miSignal Scan' is not a medical device. It determines risk by statistically calculating analyzed information and does not replace a 'diagnosis' of whether one has cancer as a medical practice. Even if the risk is determined to be low, it does not guarantee that there is no cancer or that one will not get cancer in the future.

* Ovarian and breast cancers are for women only; prostate cancer is for men only.
