This animal study suggests that nebulized iron colloids can reach (or possibly even accumulate to some extent) in certain lymph nodes in the lungs (mediastinal and hilar). This suggests (at least to me) that cancer in these specific lung lymph nodes is a possible indication for nebulized ionic silver and/or nebulized ultrafine colloidal silver and/or any anticancer agent that can be safely nebulized. We know that silver ions are quickly cleared from the lungs in animals, but only silver colloids less than a modal diameter of 15nm are cleared from the lungs. David
