Is there any help for someone in stage 4 colon cancer?

Yes. There are multiple options depending on the particulars of locations of the tumors, prior therapy, and your health status. Treatments may include surgical resection, chemo/targeted therapy, ablations, embolizations, radiation. Seek out a multidisciplinary team including experienced surgical, medical and radiation oncologists. Consider joining a clinical trial if available.
Certainly. Stage 4 colon cancer is no death sentence. Depending on your situation, there may be options for surgery, ablation, and systemic treatments like chemotherapy. I suggest that you seek help at a nationally recognized cancer center (www.Cancer.Gov).
Yes. Substantial progress has been made in the treatment of stage IV colon cancer over the past 10 years. There are several chemotherapy drugs available and in patients with liver only or liver dominant disease, there are liver directed therapies available to try to control the liver component of the disease.
