Radiation Therapy: What to Expect
While radiation therapy is one of the most common treatments for gastrointestinal cancer, at AdventHealth Cancer Institute, we do it with uncommon expertise, guidance, and compassion. Using sophisticated radiation technology, we can target tumors including rectal cancer, gastric cancer, liver cancer, and pancreatic cancer with amazing precision, easing your pain and leaving healthy tissue untouched. Depending on your diagnosis, your dedicated team may recommend radiation alone, but in many cases, we combine it with surgery, chemotherapy, and sometimes other treatment options.
How Does Radiation Therapy Work?
Our oncology experts take an individualized approach to every patient’s treatment plan. Radiation therapy targets specific areas of the body, shrinking tumors and killing cancer cells by damaging their DNA.
When treating digestive tract cancer, radiation therapy is usually delivered one of three ways:
-
External radiation, which delivers radiation in a concentrated beam to keep nearby healthy tissue unaffected, often using imaging to guide the treatment.
-
Internal radiation delivers concentrated doses of radiation guided by ultrasound, keeping healthy nearby tissue safer.
-
Systemic radiation is a treatment that is swallowed or injected and then travels through your bloodstream to target and shrink cancer cells.
Throughout your treatment, your nurses and your radiology care team are there to keep you and your support system informed, comfortable, and uplifted.
