A Long Island woman is suing Johnson & Johnson, claiming that 50 years of using its talcum powder gave her ovarian cancer.

Sylvia Fisher says in her Brooklyn federal suit that she had been applying the powder on her intimate areas since 1960. She was diagnosed with cancer in November 2013.

She has undergone debilitating treatments, says the suit, which claims the manufacturing giant ignored studies suggesting a link between talcum powder and cancer.

Johnson & Johnson is reportedly facing some 2,000 suits claiming talcum powder gave users cancer. A rep did not respond to a request for comment.
