Tony Scott Suicide -- NO Brain Cancer

Tony Scott did NOT have inoperable brain cancer, or for that matter brain cancer at all  ... this according to Scott's family.

TMZ has learned ... Scott's wife told investigators the rumor that Tony had inoperable brain cancer is "absolutely false."

Although the autopsy results have been deferred pending more tests, our sources say there is no evidence of brain cancer.

What's more ... we're told Scott's wife says Tony did not have any other severe medical issues that would have caused him to take his own life.
