Joan Kane, MD

After thirteen years in solo oncology practice in Drexel Hill, PA , Dr. Kane joined Dr. DeGreen’s practice in 1990. She is a graduate of Dickinson College and a 1970 graduate of Hahnemann Medical College. After completing an internship and Internal Medicine residency at Reading Hospital, she trained in Hematology at PUPMC and Medical Oncology at Hahnemann in Philadelphia. She resides in Lancaster County with her husband and three children. She also has had involvement in Hospice of Lancaster County as a member of its multi-disciplinary team.

Dr. Lena Dumasia

Lancaster Cancer Center is pleased to present the newest member of our medical team, Dr. Lena Dumasia. Dr. Dumasia is enthusiastically coming to Lancaster from Toms River, New Jersey. She was a scholarship student at NYU, attended Saba University School of Medicine, and completed her internal medicine residency at Hahnemann University School of Medicine and St. Joseph Mercy Hospital in Ypsilanti, Michigan. She served her fellowship in hematology/oncology at Providence Hospital and the University of Michigan Hospitals in Ann Arbor, Michigan. Her list of accomplishments is lengthy, but, most importantly, she is looking forward to serving patients in Lancaster County.

Cancer is an unexpected and unwanted illness. It will change your life forever in a way that no other illness can. You have the power within you to battle it and in the end, emerge as a stronger person. As your physician, I will help you uncover that strength. This is my passion, role and duty as your oncologist.
Dr. Lena Dumasia
