Can a tumor on the spleen be caused by rat poison or any other type by causing internal bleeding in a dog?

A tumor on the spleen is typically not directly caused by rat poison or internal bleeding. However, rat poison can lead to conditions like hemorrhaging or liver damage, which may indirectly affect the spleen's health. If the spleen is damaged or under stress from other health issues, it could potentially develop tumors or lesions over time. It's essential to consult a veterinarian for accurate diagnosis and treatment if poisoning is suspected.
