Shannen Doherty Reveals Breast Cancer Diagnosis, Sues Business Management Company

Shannen Doherty is battling breast cancer.

The 44-year-old former Beverly Hills, 90210 star revealed the sad news during a court proceeding on Wednesday (August 19) in Los Angeles.

According to court documents, Shannen learned she had breast cancer in March 2015, and that it spread during an insurance lapse, which she alleges was the responsibility of her business manager Tanner Mainstain.

“The relationship between a business manager and its client is based on trust, in honesty and competence,” her attorney Devin McRae wrote in a statement (via ABC News). “That trust was violated here, and we hope that the defendants will correct it in a responsible manner.”

Meanwhile, the business management company’s attorney Randall J. Dean said, “Tanner Mainstain is saddened to learn that Ms. Doherty is suffering from cancer and wishes her a full recovery. However, the claim that Tanner Mainstain caused her to be uninsured, prevented her from seeking medical care, or somehow contributed to her cancer is patently false. Tanner Mainstain will aggressively defend all of Ms. Doherty‘s claims in court.”
