Los Angeles: Actor Tom Cruise is reportedly worried that he might die of cancer like his father.
"Cruise turned 50 in July, and that's a year older than the age his dad died," showbizspy.com quoted a source as saying.
"With a young daughter to worry about, he has to be thinking about his mortality," the source added.
Cruise's dad Thomas Mapother III died of "metastatic rectal carcinoma" in January 1984.
The actor's family had previously voiced concerns when he quickly dropped 15 pounds after Katie Holmes filed for divorce in June.
