Cancer isn't fair. It can grow slowly and cause few problems like prostate cancer or it can spread like wildfire and cause a quick death like astrocytomas of the brain. Whether it is diagnosed early or late, it isn't necessarily the tumor itself that kills a person, it is the complications that it brings.
Some cancers grow locally to the point they obstruct structures that are in the neighborhod and cause problems. Some cancers affect the elctrolyte balance in the body. Some cancers bleed. Some cancers spread through the blood stream or lymph system and affect distant organs. And some cancers do all or any combination of the above.
To decide why a cancer wasn't readily diagnosed or why a patient died quickly is more a philosophic question rather than a scientific one. And once a diagnosis is made, it is reasonable for the patient and the family to decide how aggressive an approach to take. It is the physician's responsibilty to guide those decisions but it is also fair for the pateint to disagree and seek alternative opinons.
But just like instant replay can show what happened retrospectively, it is easy to look back and play what if games. For patients and families who have to deal with cancer, looking forward is probably the best game plan.
