For Oropharynx OC, I believe the percentage attributed to other "unknowns" was roughly 15% in the May 2007 study:
Case�Control Study of Human Papillomavirus and Oropharyngeal Cancer (Maura L. Gillison, Johns Hopkins et al...)
The way the study presents this "slice of the pie" using odds ratios and seemingly very broad Confidence Intervals for each of these possible (but perhaps unlikely) risk factors makes it hard for me to be sure if I am understanding it properly.
("Unknowns" being genetic, various dental hygiene factors, diet, low BMI, and others mentioned in the study)
