Tumour growth is conventionally understood to follow exponential kinetics in many medico-legal courts and summaries. According to this model, the time required for one cell to divide into two is equivalent to that required for two to form four, four to form eight, and so forth. As such, people from claimants to plaintiffs, physicians to patients, and scientists to laymen alike mistakenly assume that, upon determining the doubling time of a hepatic tumour, to give a typical example, the tumour would have likely been present “years ago” in the liver, and the cancer was thus “incurable” years ago. Alas, some say, there was no point in screening, testing, and diagnosing the primary tumour earlier, as it was fatal all along, owing to its metastatic spread. In other words, the patient’s tumour was metastatic well in advance of diagnosis and, hence, there would not have been any prospect of cure with earlier detection.
