Beverly Hills 902010 actress Shannen Doherty is not only fighting for her life, but she’s fighting in court to sue her business management. She’s claiming that because they neglected to pay for her insurance, she was not able to catch her breast cancer early enough.

The 44-year-old actress' health crisis was revealed when she filed a lawsuit against her former business manager, who she claims allowed her health insurance to lapse, TMZ reported Wednesday. The Beverly Hills, 90210 vet may have to get a mastectomy and undergo chemotherapy.

Soon after the star told People, "Yes, I have breast cancer, and I am currently undergoing treatment."

She added, "I am continuing to eat right, exercise and stay very positive about my life. I am thankful to my family, friends and doctors for their support and, of course, my fans who have stood by me."

Court documents claim that Shannen discovered she had invasive breast cancer in March, and that it had spread during a time when she was uninsured. Shannen claims she didn’t know that when she was fired by her management firm, her insurance was terminated.

“In November 2013, SAG sent the premium invoice to Tanner Mainstain for Plaintiff’s medical insurance coverage for the year 2014,” states the complaint obtained by The Hollywood Reporter. “However, Defendants ignored it, failed to pay it (without informing Plaintiff) and then promptly terminated their relationship with [Doherty] effective February 7, 2014.”

The complaint continues, “Plaintiff was also informed that, had she been insured and able to visit her doctor, the cancer could potentially have been stopped, thus obviating the need for the future treatment (including mastectomy and chemotherapy) that Plaintiff will likely have to suffer through now.”

Doherty has suffered “severe emotional distress” and been unable to work since the diagnosis, the filing says.

The lawsuit further claims that the company mismanaged Doherty’s money, failed to pay her taxes on time and overcharged her in fees.

The firm at the center of Shannen Doherty's lawsuit has released the following statement in response to the allegations:

"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."

Shannen Doherty is an American actress, producer, director and author who has a net worth of $10 million according to Celebrity Net Worth.
