Treatment Philosophy

Breast cancer care is constantly evolving and advancing, and I feel fortunate that my surgical practice can be focused exclusively on patients with breast cancer, those at high risk for it, and those with complex benign breast conditions. Use of a multidisciplinary approach, opportunities for clinical trials, and distribution of quality information to patients are opportunities that I strongly value when providing care to patients. 

My philosophy is that offering patients a strong physician-patient relationship built on trust, collaboration, and kindness, as well as valuing the “whole patient” are also strong tenants of cancer care. I believe in providing patients with knowledge and conversation in order to help them make the best treatment decisions for themselves. Fox Chase Cancer Center provides high quality care and extensive resources to patients, and I feel honored to be a part of such an excellent team and institution that believes so strongly in compassionate and thoughtful care.

    Dr. Algonn was wonderful to speak to regarding my health care. She is taking over Dr. [...]'s cases. She was upbeat even though I was the last patient of the day and as a medical professional, I know how challenging that can be. This was our first exam and meeting together, and she was quite familiar with may case and answered all of my questions. I look forward to seeing her again to help manage my medical concerns.

    Dr Aggon goes above and beyond. I had a concern about some soreness and she ordered a stat ultrasound- they squeezed me in within 15 minutes - and the radiologist was in the room real-time explaining the ultrasound and giving results immediately. I felt so so much better. It was amazing having immediate results. both Dr Aggon and the wonderful radiologist were thorough, caring and helpful. After Dr [...] left, I was worried that my new breast doctor would not compare- however, Dr Aggon truly lives up to the high standards that dr [...] set. Thank you Dr Aggon for all you do for my physical and mental well being as a breast cancer survivor!!!
