Shannen Doherty Battling Cancer Again

Shannen Doherty admitted Tuesday that she is again battling cancer, three years after being treated for breast cancer. The actress, 48, revealed to "Good Morning America" that she has been living with this round privately for a year and that it is stage 4, though she did not elaborate on the type.

She decided to reveal her diagnosis due to a lawsuit with her homeowner's insurance. Legal documents related to the suit make mention of her condition and will soon go public.
