- Brachytherapy: In this method, radioactive seeds or sources are implanted directly into or very close to the tumor. This allows for a high radiation dose to the tumor while reducing exposure to nearby healthy tissue. Brachytherapy is often employed in prostate cancer and some gynecological cancers.
- Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT): These advanced techniques deliver very high doses of radiation to small, well-defined tumors in one or a few sessions. They are commonly utilized for brain tumors and metastatic cancers.
The delivery of radiation therapy is typically organized into sessions, with the frequency and dosage tailored to the individual patient’s treatment plan. The total dose is divided into smaller doses or fractions, which are administered over several sessions. This fractionation allows healthy cells to recover between treatments while maximizing the impact on cancer cells.
“Fractionation helps in achieving a balance between effective tumor control and minimizing side effects.”
The total treatment duration may vary based on the cancer type, but common regimens can range from daily sessions over several weeks to more intensive schedules in specialized cases. Understanding the precise methods of delivery is essential for both patients and healthcare providers to gauge treatment effectiveness and manage potential side effects efficiently.
