Our Mission

To Advance Women's Health and Contribute to Global Cervical Cancer Elimination

At our clinic, we are dedicated to preventing cervical cancer through HPV vaccination, regular screenings, and early treatment. These efforts align with the WHO's global cervical cancer elimination strategy, which aims to achieve:

  • 90% HPV vaccination coverage among girls by age 15

  • 70% of women screened by age 35 and again by age 45

  • 90% of women with pre-cancer treated and invasive cancer managed

 

By participating in these global initiatives and contributing to groundbreaking research, we strive to bridge the gap in cervical cancer prevention efforts worldwide. Together, we can create a future free from preventable diseases. Let's explore how our clinic supports these goals through our services.

About the Doctor/Expertise

I have dedicated my career to advancing women's health, specializing in gynecological oncology and surgery, with extensive experience in both clinical practice and research. My research, conducted at Osaka University and the National Cancer Center, has focused on the effectiveness of HPV vaccination to prevent CIN and cervical cancer. This work contributed to establishing critical evidence that supported the Ministry of Health, Labour and Welfare's decision to reinstate proactive recommendations for the HPV vaccine in Japan.These experiences have profoundly deepened my understanding of the importance of health promotion and preventive medicine in ensuring the long-term well-being of my patients.

Building on this foundation, I am committed to offering outstanding clinical opportunities for women's health. I will always provide patient centred care (not disease centred) with compassion and understanding. We will offer less invasive, high standard, and comprehensive gynaecological care to meet women's health and wellness needs for every phase of life.

I believe in empowering women through knowledge, support, and evidence-based treatment options that enhance both longevity and quality of life.
