Marthia NicholsMarthia Nichols, RN, MSN, MHA

Marthia N. Nichols is the Patient Navigator at the Cheryl R. Lindenbaum Comprehensive Cancer Center. Marthia is a certified oncology nurse and holds a Master’s of Science in Nursing and a Master’s of Healthcare Administration. She has been an oncology nurse for six years and has a passion for women’s health. Becoming an Oncology Patient Navigator was a natural career choice for Marthia, who became a nurse after caring for her own father throughout his battle with cancer. “Everyone deserves an advocate for their health care needs especially, when your life depends on it,” she said. Marthia enjoys gardening.

The role of the Nurse Navigator is to assist patients in understanding their diagnosis and treatment, facilitate their work up and treatment schedule and to identify patient and family needs for support and community resource referral.  The average patient with a suspected or known cancer diagnosis is faced with appointments and information from no less than five specialists as well as information and advice from well-intended family and friend and the media.  In a time of crisis, this is truly overwhelming and can delay treatment and follow-up while patients and families sort through the information.  The role of the Nurse Navigator provides that one point of contact for clarification of information, coordination of care, reinforcement and support. Marthia can be reached at 914-293-8402.

The latest technology


Conventional radiation treatment devices are at the end of an evolutionary path that began more than a century ago. Our center, in contrast, uses The TomoTherapy® Hi·Art® treatment system.

The system relies on secure centralized database software for treatment planning, quality assurance, patient set-up and treatment delivery. While conventional radiation therapy machines use five to nine beam angles, the Hi·Art treatment system delivers radiation continuously from all angles around the patient. The increased beam angles, along with  more precise beam modulation, create dose distributions that conform to complex tumor shapes. In addition, the TomoTherapy System integrates the use of a CT Scanner for more accurate planning. Traditionally, a patient is imaged weekly during the course of radiation therapy. With the TomoTherapy system, the physician gains valuable information from daily low dose imaging. This practice enhances the accuracy of treatment and significantly reduces the amount of exposure to healthy tissue by providing daily information about the target’s location, shape and size.

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.The Ashikari Breast Center welcomes its newest surgeon, Dr. Melita Charles.

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.
