Colorectal Cancer Screening Day

What Is Colorectal Cancer Screening Day?

September 1st is "Colorectal Cancer Screening Day" in Japan. It was established by Brave Circle, a Tokyo-based nonprofit that encourages people to get colorectal cancer screening and follow-up examinations, and was certified and registered by the Japan Anniversary Association in 2019. The date was chosen because it is the first day of "Cancer Control Month," the September awareness campaign led by the Japan Cancer Society.

Why Does Colorectal Cancer Screening Matter So Much?

Colorectal cancer is one of the most commonly diagnosed cancers in Japan and among the leading causes of cancer death. At the same time, it is said to have a high chance of cure when found and treated early — making regular screening for early detection more important than almost anything else.

• How it's done: screening is typically done through a simple, low-burden fecal occult blood test
• Few symptoms: because colorectal cancer often shows no early symptoms, regular screening is recommended even when you feel completely healthy
• Awareness campaign: every September, the Japan Cancer Society produces "Cancer Control Posters" displayed in municipalities, hospitals, and companies nationwide

What Is "Cancer Control Month"?

Since its founding in 1958, the Japan Cancer Society has worked continuously to raise awareness of cancer prevention, early detection, and treatment. Every September, "Cancer Control Month" brings lectures, events, and poster campaigns nationwide, all aimed at boosting cancer screening participation rates.

Tips for Marking This Day

• Try to recall the last time you or a family member had a colorectal cancer screening
• Book a fecal occult blood test through your local municipality's or workplace's health checkup program
• Look up accurate information about colorectal cancer symptoms and risk factors
• Talk with family about the importance of regular cancer screening

Get Screened Before Symptoms Appear — Not "Because" There Are None

By the time colorectal cancer produces noticeable symptoms, it has often already progressed significantly. That's exactly why the right mindset isn't "I'm fine because I have no symptoms" but rather "get screened while there are no symptoms." Let September 1st be the nudge you need to take one step toward protecting your health and the health of those you love.
