Radiation therapy plays a crucial role in cancer treatment, utilizing high-energy particles or waves to destroy cancer cells. Understanding the basics of radiation therapy and its various types is essential for individuals undergoing cancer treatment or supporting a loved one through the process. In this blog post, we will delve into the fundamentals of radiation therapy and explore its different types, providing valuable insights for those seeking information on this integral aspect of cancer care.
The Basics of Radiation Therapy
Radiation therapy, also known as radiotherapy, is a common treatment for cancer. It uses high-energy radiation to shrink tumors and kill cancer cells. Here are some key points to understand about radiation therapy:
- Purpose: Radiation therapy is used to either cure or control the growth of cancer. It can be used alone or in combination with other treatments such as surgery or chemotherapy.
- Types: There are two main types of radiation therapy – external beam radiation and internal radiation (brachytherapy).
- Process: During the treatment, the patient lies on a table while a machine delivers radiation to the specific part of the body where the cancer is located.
- Side Effects: While the goal is to target cancer cells, radiation therapy can also affect nearby healthy cells, leading to temporary side effects such as fatigue, skin changes, and nausea.
Understanding the basics of radiation therapy is crucial for patients and their families to make informed decisions about cancer treatment options.
Types of Radiation Therapy
When it comes to treating cancer, there are different types of radiation therapy that can be used, depending on the specific needs of the patient. These types include:
- External Beam Radiation Therapy (EBRT): This type of therapy delivers radiation from a machine outside the body directly to the cancer.
- Internal Radiation Therapy (Brachytherapy): In this type, a radiation source is placed inside the body, close to the cancer. It allows a higher dose of radiation to be delivered in a smaller area.
- Systemic Radiation Therapy: This approach involves the use of radioactive substances, such as radioactive iodine, that travel in the blood to reach cancer cells throughout the body.
Each type of radiation therapy has its own advantages and considerations, and the choice of therapy depends on the type and location of the cancer, as well as the patient’s overall health.
