Following oral or inhalation exposure to silver compounds, humans excrete
silver primarily in the feces and only very minor amounts in the urine
(East et al., 1980; Newton and Holmes, 1966). In rats and mice, the
cumulative recovery of silver in the feces was 98-99% on the second day
after oral exposure to silver; monkeys excreted 94% (U.S. EPA, 1985). Dogs
excreted approximately 90% of an inhaled dose of metallic silver particles
[finely ground dust] in the feces within 30 days of exposure (Phalen and
Morrow, 1973).
No one knew how to make 15 nm < particles in 1973

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.
