Question by sonia: People talk about cancer survival in 2, 5, 10 year intervals. When does the clock start?
Does it start when the cancer is discovered? When they think the cancer started growing? If it has metastasized from somewhere else, does the clock start over again? My husband learned he had kidney cancer in 2007. He had a complete nephrectomy in October. The doctor told him that the tumor had probably been growing for two years before we found it. Last September the kidney cancer spread to the plural lining in his lungs. Now it has spread to his lymph nodes. If he has a 5 year expected survival rate, when did the clock start?
