When setting up a GoFundMe for someone diagnosed with colorectal cancer, the amount to set depends on the stage of cancer, treatment needs, and ongoing care. Here's a general breakdown of potential expenses:

1. Medical Treatments: Treatment for colorectal cancer can include surgery, chemotherapy, radiation therapy, and possibly immunotherapy or targeted therapy. Costs can range from $50,000 to $200,000+, depending on the stage and complexity of treatment.

2. Surgery & Hospitalization: Major surgeries (like bowel resections or colostomies) and hospital stays may cost anywhere from $20,000 to $100,000, depending on the procedure and any complications.

3. Chemotherapy & Medications: Chemotherapy cycles can cost anywhere from $10,000 to $50,000 per cycle, with several cycles often required, plus additional costs for prescription medications and targeted treatments.

4. Ongoing Care: Follow-up visits, scans, physical therapy, and supportive care for side effects or rehabilitation could add another $20,000 to $50,000 or more per year.

5. Lost Wages & Caregiving: If the person is unable to work or needs someone to help with caregiving, lost income or expenses related to assistance can be significant.

A reasonable starting goal might be $50,000 to $150,000, but if the treatment is extensive or prolonged, you could aim for $200,000 to $300,000 or more to cover the entire process of diagnosis, treatment, recovery, and potential financial strain.
