1. Purpose of the Site ― To help you quickly find trustworthy doctors and hospitals
doctor-cancer.com is a medical information site that introduces “renowned doctors and specialists” treating serious diseases, primarily cancer, as well as neurosurgery, heart disease, and orthopedics (especially back and knee pain).
While Japan has many excellent doctors, this information is often difficult for patients to access. We frequently hear patients say, “I don’t know which hospital or doctor to choose.”
This site is operated with the goal of helping such patients and their families find trustworthy specialists as quickly as possible and make treatment choices they feel confident about.
It is not a site designed to strongly push for appointments; its purpose is solely to provide information to help you evaluate treatment options.
2. Background of Establishment — From My Personal Experience of Struggling to Choose Hospitals and Doctors
As the administrator of this site, I became acutely aware of the difficulty in choosing hospitals and doctors after experiencing cancer in my family and my own illness.
Even with the same diagnosis, the treatment methods and approaches explained by different doctors varied, and the information online was a mixed bag—it was unclear what to believe.
This state of uncertainty persisted for a long time.
Amidst this, I personally experienced how encountering “doctors with truly extensive treatment experience” or “doctors with outstanding expertise in specific fields” could significantly change both the quality of treatment and my peace of mind.
This experience gave birth to the desire to “make the existence of renowned doctors more visible to patients,” leading me to launch doctor-cancer.com in 2014.
Since then, for over 10 years, I have continued gathering, organizing, and updating information.
3. Medical Advisor ― Dr. Haruhito Azuma, Osaka Medical and Pharmaceutical University Hospital
For the medical validity of this entire site, we have requested professional advice (partial supervision) from Professor Haruhito Azuma of the Department of Urology at Osaka Medical College Hospital, who is internationally renowned in the field of urological surgery.
Professor Azuma is a highly trusted specialist in the medical community, with extensive experience in treating urological cancers, including bladder and prostate cancer, particularly in advanced medical treatments such as robot-assisted surgery. He is recognized through his presentations at domestic and international conferences, publications, and educational activities.
doctor-cancer.com receives advice from Professor Azuma regarding the overall site structure, appropriateness of expression, and medical balance, ensuring information is provided in compliance with medical advertising guidelines and relevant regulations.
However, the content of individual pages does not necessarily represent the personal views of Professor Azuma.
4. Disease Areas Covered and the Site’s Role
doctor-cancer.com primarily covers the following areas:
- General Cancer (Breast Cancer, Stomach Cancer, Colorectal Cancer, Lung Cancer, Prostate Cancer, etc.)
- Neurosurgery (Brain Tumors, Brain Aneurysms, Stroke, etc.)
- Cardiovascular & Cardiac Surgery (Angina Pectoris, Myocardial Infarction, Valvular Heart Disease, etc.)

Each disease page outlines fundamental treatment concepts and representative therapies, then introduces physicians and medical institutions with high expertise and proven results in that field, organized by region and specialty.
This site is an informational resource, not a medical institution, and is not intended for diagnosis or determining treatment plans.
For actual medical care, always consult a medical institution and discuss with your attending physician.
5. Selection Criteria for Renowned Physicians and Specialists
There is no official definition for the term “renowned doctor.”
At doctor-cancer.com, we strive to maximize objectivity and transparency by comprehensively evaluating physicians and medical institutions based on the following criteria:
- Official qualifications such as specialist and instructor certifications from relevant medical societies, and accreditation as a certified facility
- Clinical experience and surgical case volume at university hospitals, cancer centers, and major hospitals
- Academic achievements including conference presentations, published papers, and authored books
- DPC data and statistical information published by the Ministry of Health, Labour and Welfare and local governments
- Content regarding clinical performance and specialties on hospital official websites
- Attitude toward public outreach, such as patient-oriented lectures and information provision
Based on this information, we primarily feature physicians and medical institutions that we judge to possess high expertise and experience in specific fields and to be continuously engaged in clinical practice.
Please understand that this does not negate the value of physicians or hospitals not listed here.
Due to limitations in the scope of our research and the volume of information available, we cannot cover everything.
6. Sources and Editorial Policy/Neutrality

8. The Future of doctor-cancer.com
Over the years since our site launched, we have received valuable feedback, information, and links from university hospitals, general hospitals, and specialists nationwide.
However, disparities in access to medical information and the anxiety of “not knowing where to turn for advice” persist to this day.
doctor-cancer.com will continue to work in collaboration with our network of specialists to expand the range of diseases covered, update information, and create easy-to-understand content.
Our mission is to grow as a “platform for reliable information on leading specialists” so that as many patients and their families as possible can make treatment choices without regret.
