In EBRT, external sources generate radiation that targets the tumor from outside the body. Several types of radiation are utilized, including X-rays and gamma rays, each with its characteristics regarding penetration and effectiveness.
When radiation is absorbed by cells, it causes damage to the DNA, leading to cell death or disruption of the cell cycle. This type of therapy is often prescribed after careful imaging and diagnosis, often utilizing tools such as MRI or CT scans to delineate the tumor's location accurately.
- Radiation Sources: Often include linear accelerators which create high-energy beams.
- Delivery Techniques: Radiologists may employ various delivery methods to optimize radiation's effect on the tumor itself.
- Treatment Duration: Radiation therapy typically involves multiple sessions, allowing healthy tissues to recover between exposures.
With the correct dosage and treatment regimen, EBRT can effectively reduce tumor size and contribute to better overall patient outcomes.
Cellular Effects of Radiation
The cellular effects of radiation are multi-faceted. At a basic level, radiation damages the DNA inside cancerous cells. This damage can occur in several forms, distinctly categorized as:
- Direct DNA Damage: This happens when radiation impacts the DNA molecule directly, leading to immediate dysfunction.
- Indirect DNA Damage: This occurs when radiation interacts with water molecules in the cells, leading to the creation of free radicals. These free radicals subsequently damage DNA.
Both forms of damage lead to cell death or, at the very least, significant disruption of cellular function. However, not all cells die immediately; some may undergo repair mechanisms. This recovery can be detrimental. Cells that manage to repair damage can sometimes adapt and develop resistance to subsequent treatments.
"Understanding how radiation affects cells is essential to enhancing treatment efficacy and minimizing side effects."
Moreover, the effectiveness of EBRT is influenced by factors such as:
- Cell Cycle Phase: Cells are more susceptible to radiation during certain phases, particularly during mitosis.
