Why didn't my oncologist recommend radiation for my stage 4 colon cancer?

Treatment decisions for colorectal cancer can vary significantly based on many factors including the stage, location, and specific characteristics of the cancer, which is why different patients may receive different recommendations. Radiation therapy is more commonly used for rectal cancers or in specific situations where it can target localized areas, while systemic treatments like chemotherapy are often preferred for metastatic disease that has spread to multiple organs like the liver and ovaries. It's completely understandable to feel confused when seeing others with similar diagnoses receiving different treatments, and this could be a great question to revisit with the oncology team to better understand the reasoning behind the specific treatment plan.
