- Melanoma & Advanced Skin Cancers: Aggressive forms of skin cancer, where oncologists manage systemic treatments like immunotherapy or targeted therapy for advanced or metastatic disease.
Common Areas/Cancers Treated with Radiation Oncology
- Thoracic Cancers (e.g., Lung Cancer, Esophageal Cancer, Mesothelioma): Using radiation therapy to treat cancers within the chest cavity, often combined with other modalities.
- Gastrointestinal Cancers (e.g., Rectal, Anal, Pancreatic, Stomach): Role of radiation therapy in managing various cancers of the digestive system, often as part of combined modality treatment.
- Central Nervous System (CNS) Tumors (Brain & Spine): Employing precise radiation techniques to treat benign and malignant tumors of the brain and spinal cord.
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. Kang Zeng or your referring physician.
- 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).
- Second Opinion Consultations for Cancer & Blood Disorders: Providing expert second opinions on complex diagnoses and proposed treatment plans to ensure informed decision-making.

Cancer care programs often have centralized intake systems that manage referrals to ensure timely access.
- What is Radiation Oncology and when is it used?
- Radiation Oncology is a medical specialty that uses high-energy radiation (like X-rays, gamma rays, or charged particles) to damage or destroy cancer cells and shrink tumors. It can be used as a primary treatment, before surgery (neoadjuvant), after surgery (adjuvant), or in combination with chemotherapy. It can also be used for palliative care to relieve symptoms. Dr. Zeng specializes in planning and delivering radiation therapy using techniques like EBRT, IMRT, SBRT, or brachytherapy. Dr. Zeng may refer patients to a Radiation Oncologist if this treatment is indicated for their type of cancer as part of a multidisciplinary care plan.
- What does an Oncologist and/or Hematologist like Dr. Zeng specialize in?
- An Oncologist specializes in the diagnosis and treatment of cancer. This can include Medical Oncologists who use systemic treatments like chemotherapy and immunotherapy, Radiation Oncologists who use radiation therapy, and Surgical Oncologists who perform surgery to remove tumors. A Hematologist specializes in diagnosing and treating disorders of the blood, bone marrow, spleen, and lymph glands; this includes benign conditions like anemia and bleeding disorders, as well as malignant conditions (blood cancers) like leukemia, lymphoma, and myeloma. Dr. Zeng has expertise in Radiation Oncology, focusing on the use of radiation to treat cancer.
- Does Dr. Zeng participate in or offer access to clinical trials?
- Many oncologists and hematologists are involved in clinical research to advance cancer treatment and care for blood disorders, as participation in clinical trials can offer access to new and investigational treatments. Dr. Zeng is actively involved in clinical trials and may discuss relevant trial options with you if you are eligible and it is appropriate for your condition. You can ask Dr. Zeng if there are any suitable clinical trials available for your condition, either at Dr. Zeng's institution or through collaborative research networks. He can provide information or refer you for consideration.
- What is targeted therapy in cancer treatment?
- Targeted therapy uses drugs or other substances to identify and attack specific types of cancer cells with less harm to normal cells. These therapies work by targeting specific genes or proteins found in cancer cells or cells related to cancer growth, like blood vessel cells. Genetic testing of the tumor is often done to see if a targeted therapy is likely to be effective. Dr. Zeng can explain if targeted therapy is an option for your cancer.
