About Breast Cancer

Dr. Coral Quiet

Creating Arizona Breast Cancer Specialists (ABCs), dedicated to exclusively treating women with breast cancer with radiation, has been a dream of Dr. Robert Kuske and Dr. Coral Quiet’s for the last decade…and it’s the first center like it in the world. No other radiation practice has committed its physicians, staff and equipment exclusively for women fighting breast cancer! We have chosen equipment that offers the best types of radiation to direct against cancer; yet allows minimal collateral damage to normal tissues. Our state-of-the-art equipment is specifically designed for treating breast cancer. 

Studies have shown that patients going to sub specialists for one disease have better outcomes. We are proud to be the inventors, original pioneers in research, and the word wide authority in accelerated partial breast irradiation (APBI). APBI is mostly done with brachytherapy, although it can also be delivered using multiple radiation beams targeting where the breast cancer started. Brachy therapy uses a tiny radioactive seed to treat the breast from the inside out. For women with early stage localized breast cancer, brachytherapy provides the tightest, most conformal radiotherapy know to humankind.

Dr. Robert Kuske and Dr. Coral Quiet are Radiation Oncologists who specialize in the treatment of breast cancer. Together, they have over 60 years of experience treating this disease in both top tier academic teaching institutions and in private practice and have been honored by the opportunity to help pioneer new developments in breast cancer treatment. As they have worked in the Scottsdale and Phoenix area for years, they have dreamed of building a breast cancer specialty clinic. Today, that dream has been realized!

We have spared no expense in choosing only the very best technology, engineered by the most innovative and experienced companies in the world. Each staff member and piece of equipment is impressive in its own right, but when joined together with the dedication of the collaborating physicians, and the spirit and resolve of you, our patients, we have created a true team of champions for your fight against breast cancer.

We are experienced in all facets of breast cancer radiation therapy. We are recognized for our work with conventional external beam radiotherapy. We pay great attention to treating the areas that need radiation, while sparing the vital organs underneath, the breast, the lung and heart.
