Shannen Doherty Reveals She is Battling Breast Cancer

Shannen Doherty has sadly been diagnosed with breast cancer.

The 44-year-old actress revealed the news while filing a lawsuit against her business managers, whom she claims allowed her health insurance coverage to lapse, TMZ reported earlier today.

According to court documents obtained by the entertainment news website, Shannen said her managers previously ignored an invoice for payment of her premium last year and her insurance was consequently cancelled.

The former Beverly Hills, 90210 star further claimed she wasn't able to re-enroll in her health insurance until 2015 and thus missed regular doctors visits, causing her breast cancer to go undetected for some time.

Shannen then confessed she was diagnosed with "invasive breast cancer metastatic to at least one lymph node," in March. According to her doctors, the actress' cancer did spread to other parts of her body during 2014 while she was uninsured.

In the filing, Shannen asserted she may now have to undergo a mastectomy and receive treatment including chemotherapy to combat the disease.
