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. Mui specializes in planning and delivering radiation therapy using techniques like EBRT, IMRT, SBRT, or brachytherapy. Dr. Mui 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 can I expect at my first appointment with an Oncologist/Hematologist?

Your first appointment with Dr. Mui will be comprehensive and may last an hour or more. It will involve a detailed review of your medical history, family history of cancer, current symptoms, medications, and any previous tests, imaging results (CT, MRI, PET scans), and biopsy reports related to your diagnosis. He will likely perform a thorough physical examination. The main goals are to confirm your diagnosis, discuss the type and stage of your condition (if applicable), and outline potential treatment options. This is a crucial time to ask questions, and you are encouraged to bring a family member or friend for support and to help take notes. Dr. Mui will explain the proposed treatment plan, including goals, benefits, potential side effects, duration, and what to expect moving forward. Further tests may be ordered.

What is palliative care, and when might Dr. Mui discuss it?

Palliative care is specialized medical care focused on providing relief from the symptoms and stress of a serious illness, like cancer or advanced blood disorders. The goal is to improve quality of life for both the patient and the family. It can be provided at any stage of illness, alongside curative treatments, not just at the end of life. Dr. Mui may discuss palliative care if you are experiencing significant symptoms, to help manage pain, fatigue, nausea, anxiety, or other issues, and to provide an extra layer of support.

What does an Oncologist and/or Hematologist like Dr. Mui 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. Mui has expertise in radiation oncology, focusing on the use of targeted radiation treatments for various cancers and blood disorders.

Does a Hematologist only treat blood cancers?

No, Hematologists treat a wide range of blood disorders, not just cancers. This includes benign (non-cancerous) conditions such as various types of anemia (e.g., iron deficiency anemia, vitamin B12 deficiency, sickle cell anemia, thalassemia), bleeding disorders (like hemophilia or von Willebrand disease), clotting disorders (thrombophilia, deep vein thrombosis, pulmonary embolism), and issues with white blood cells (like neutropenia) or platelets (like ITP). Dr. Mui, if focused on hematology, can diagnose and manage these conditions.

What happens after cancer treatment is completed with Dr. Mui?

After active cancer treatment finishes, Dr. Mui will develop a survivorship care plan with you. This plan typically includes a schedule for follow-up appointments and tests to monitor for any signs of recurrence, management of any long-term side effects from treatment, recommendations for healthy lifestyle choices (diet, exercise), and coordination with your family doctor for ongoing general health care. The goal is to support your long-term health and well-being.
