- Breast Cancer (Early Stage, Locally Advanced, Metastatic): Malignant tumors developing in the cells of the breast, managed with various therapies including hormonal, chemo, targeted agents, and immunotherapy.
- Lung Cancer (Non-Small Cell & Small Cell): Cancers originating in the lungs, treated with chemotherapy, targeted therapy, immunotherapy, and/or radiation based on type and stage.
Hematologic Malignancies (Blood Cancers) Treated
- Non-Hodgkin Lymphoma (NHL) (e.g., Diffuse Large B-Cell, Follicular, Mantle Cell): A diverse group of blood cancers that develop from lymphocytes, with many different subtypes requiring tailored treatments.
- Acute Lymphoblastic Leukemia (ALL): A type of cancer of the blood and bone marrow that affects white blood cells called lymphocytes, common in children but also occurs in adults.
- Chronic Myeloid Leukemia (CML): A type of cancer that starts in certain blood-forming cells of the bone marrow, often managed with targeted therapies.
Common Areas/Cancers Treated with Radiation Oncology
- Sarcomas (Bone & Soft Tissue - Radiation Aspects): Role of radiation therapy in the multidisciplinary management of sarcomas, often used before or after surgery.
- Gynecologic Cancers (e.g., Cervical, Uterine, Vaginal, Vulvar - Radiation Aspects): Application of external beam radiation and/or brachytherapy for cancers of the female reproductive tract.
- Breast Cancer (Adjuvant, Neoadjuvant, Palliative Radiation): Applying radiation after lumpectomy or mastectomy to reduce recurrence risk, or to treat metastatic disease.
This list provides examples of common conditions treated and is not exhaustive. Cancer and blood disorders are complex, and treatment is highly individualized. For personalized advice, please discuss your specific situation with Dr. John Radwan or your referring physician.
- Prophylactic Cranial Irradiation (PCI): Preventative radiation treatment to the brain for certain cancers at high risk of brain metastases.
- Brachytherapy (Internal Radiation - LDR/HDR) for Specific Cancers: Planning and performing procedures where radioactive sources are placed directly into or near a tumor (e.g., for prostate, cervical, breast cancer).
- Stereotactic Body Radiotherapy (SBRT) / Stereotactic Ablative Radiotherapy (SABR) / Stereotactic Radiosurgery (SRS): Delivering highly focused, high-dose radiation to precisely targeted tumors or lesions in the brain or body, often in a few treatment sessions.
- Image-Guided Radiation Therapy (IGRT): Utilizing advanced imaging during treatment delivery to precisely target tumors and adapt to changes, while minimizing exposure to healthy tissues.
- Palliative Radiation Therapy for Symptom Control: Using radiation to alleviate pain, bleeding, or obstruction caused by cancer.
- External Beam Radiation Therapy (EBRT) - 3D Conformal, IMRT, VMAT: Developing precise, individualized plans for delivering radiation using external machines (e.g., linear accelerators) with techniques like Intensity-Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT).
Genetic Counseling & Testing Referrals for Hereditary Cancer Syndromes: Assessment of family history and risk factors, and coordination of referrals for genetic counseling and testing for inherited predispositions to cancer (e.g., BRCA).
