The Ashikari Breast Center

Breast Cancer Surgeons

The expertise of the surgeons of The Ashikari Breast Center is now available at Hudson Valley Hospital Center.


The world renowned team of surgeons – like HVHC – is committed to providing individualized, quality care in a warm, compassionate environment, with a focus on positive results.


The Ashikari team has pioneered a breast reconstruction procedure that has attracted women from all over the world, most notably a nipple-sparing procedure that allows them to remove cancerous or potentially cancerous breast tissue, minimizing the trauma of a mastectomy. Many women, including those who are cancer-free, but have high-genetic risk and are seeking prophylactic surgery, favor this approach.


What sets the Ashikari team apart from others is their determination to use the latest and more effective techniques to eradicate cancer while fully supporting and treating the patient as a whole person.

For an appointment, call 914-734-3490 or visit their new website.


Here are just a few of the reasons why they are the leaders in their field:


  • 72-hour turnaround from the initial exam to surgical treatment;
  • Sparing more than 70 percent of patients more extensive surgery by determining whether cancer has spread to the lymph nodes before initial surgery;
  • Immediate reconstructive surgery during mastectomies to avoid repeated surgery.
  • A one-stage prophylactic mastectomy with immediate reconstruction to prevent breast cancer in patients with high-genetic risk.


The practice was founded by Dr. Roy Ashikari, a renowned breast cancer surgeon, and former Chief of The Breast Service at Sloane Kettering. He has treated thousands of patients, won prestigious awards both here and in his native Japan and published dozens of scientific articles on breast cancer.
