Turtles are attracted by the excess of food. Sooner or later, an infected turtle arrives. Turtles like to gather. When turtles gather, cleaning symbiosis starts. Cleaners learn that tumors host edible parasites.
More turtles become infected.
More cleaners discover tumors are a food source, an escalating spiral. This cycle is based primarily on observations at Honokowai and how we fit them into what we have learned from research papers on the disease. We do not know what occurs underwater at Indian River or other tumor sites. We have not, however, found any material that contradicts our thinking, while the concept does seem to fit the sites that we have information from. This does not mean we are right.
