Tom Cruise has been warned that he needs to visit hospital with Katie Holmes urgently.
Tom and Katie have been partying on a ship which contains a high level of asbestos.
It is not thought that Suri was at the party on board the Scientology cruise ship.
John Travolta is also at risk because he was at the party.
The cruise ship had a high level of the blue type asbestos.
A toxicologist told OK magazine: "This is the most dangerous type of asbestos because the fibres are smaller than the white asbestos and can penetrate the lung more easily.
"Once diagnosed with mesothelioma, the victim has six months to a year to live.
It gradually reduces lung function until the victim is no longer able to breathe and dies."
Scientologists are currently investigating the findings. Tom Cruise has not released a statement.
