Two Primary Types of Radiation Therapy For Treatment Of Lung Cancer
Radiation Therapy is a suitable method for treatment of lung cancer. There are a range of radiation therapy options available to treat all types of lung cancer. Radiation therapy for lung cancer uses high-powered energy to destroy cancer cells, shrink tumors, and provide relief of common lung cancer symptoms.
At times, radiation therapy can be damaging to the lungs. Advanced radiation therapies such as External Beam Radiation Therapy (EBRT) and High Dose Rate (HDR) Brachytherapy are used to precisely target tumors and minimize damage to healthy lung tissue and nearby organs, like the heart. During the treatment, radioprotective drugs are used to help protect healthy tissue from exposure to radiation.
Radiation therapy for lung cancer can be included in the treatment plan as a primary treatment or before surgery to shrink a tumor or after surgery to eliminate any remaining cancer cells or to treat cancer that has spread to other areas of the body.
Two primary types of radiation therapy for lung cancer treatment are as given below:
External Beam Radiation Therapy (EBRT): High doses of radiation are delivered to lung cancer cells from outside the body, using a variety of machine-based technologies. Generally, a linear accelerator is used that allows radiation to be delivered from any angle and shapes radiation beams to the contour of lung cancer tumors.
High Dose Rate (HDR) Brachytherapy (Internal Radiation): High doses of radiation are delivered from implants placed close to, or inside, the tumor(s) in the body. During the treatment, the radiation is deposited inside a tumor, delivering a maximum dose while minimizing exposure to the surrounding healthy tissue. The radiation treatment has to be tightly focused on tumors to avoid serious side effects.
These are some of the effective radiation therapy treatments for lung cancer.
