After residency, I spent time on the faculty at MD Anderson Cancer Center treating hematologic malignancies (leukemia, lymphoma and multiple myeloma). I have considerable experience treating this patient population. Because many lymphomas are highly curable, management of long term side effects from treatment is essential. I have used many different treatment techniques and modalities to minimize radiation dose to normal structures, thereby minimizing late effects from treatment. I also have a great deal of experience working with cutaneous lymphomas and the management of this category of lymphomas.

Dr. Leslie Ballas also specializes in cancers of the genitourinary tract, including malignancies of the prostate, urinary bladder, testicle, and kidney. Her research has focused on improving quality of life for men with prostate cancer. She is involved in the development of cancer treatment clinical trials for patients with genitourinary cancers. And has brought multiple genitourinary cooperative group studies to USC. Dr. Ballas’ interests include advanced technology integration into cancer therapeutics, including image-guide radiation therapy (IGRT), stereotactic body radiotherapy (SBRT), and intensity modulated radiotherapy (IMRT).
