#' Ethanol Treatment for Tumors Experiment
#'
#' Experiment where 3 different treatments of ethanol were tested on the
#' treatment of oral cancer tumors in hamsters.
#'
#' The \code{ethyl_cellulose} and \code{pure_ethanol} treatments consisted of
#' about a quarter of the volume of the tumors, while the
#' \code{pure_ethanol_16x} treatment was 16x that, so about 4 times the size of
#' the tumors.
