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.

I also had part of my colon removed and my ovaries. I also had liver surgery, and they removed my spleen and gall bladder. I have had targeted radiation to my liver with a procedure called y90. Good results and may have to do more ablation or y90 in the future. On chemo now again after a year or so off it.
