Singer Cat Janice, who went viral last month after dedicating her final song to her son, has died after a battle with sarcoma cancer. She was 31.

Janice's family announced her passing on Instagram Wednesday.

"This morning, from her childhood home and surrounded by her loving family, Catherine peacefully entered the light and love of her heavenly creator," the family captioned a photo of Janice.

The Washington, D.C. singer went viral in January after releasing the disco-pop song "Dance You Outta My Head" on streaming platforms on her birthday, Jan. 19, with proceeds dedicated to her son, Loren, as she entered hospice.

USA TODAY has reached out to Janice's family for comment.

Janice was diagnosed with sarcoma, a rare malignant tumor, in 2021. On Jan. 15, she announced that her cancer had progressed, making it impossible for her to speak, and that she is now home under the care of loved ones.

"We are eternally thankful for the outpouring of love that Catherine and our family have received over the past few months," the family's post continued. "Cat saw her music go places she never expected and rests in the peace of knowing that she will continue to provide for her son through her music. This would not have been possible without all of you."

The family went on to say her Instagram page would be memorialized by Janice's brother, who will also manage all operations surrounding her music, merchandise and public relations.

"Per Cat’s request, there is some more art that she wants to share too," the post ended. "All in due time."

"Dance You Outta My Head" has nearly 13 million streams on Spotify and has reached No. 10 on the United States iTunes chart.

Following her 2021 diagnosis, Janice has continued to make music and social media content while undergoing surgery, chemotherapy and radiation. On July 22, 2022, she was declared cancer-free and lived nearly a year without the disease. In June, the "white shoes" singer shared the news that her cancer had returned in her lungs.

In January, she told her followers that "the tumors basically tripled overnight."

The singer won the Washington Area Music Award in the Best Rock Artist category in Washington, D.C., in 2019. Last year, she was a recipient of the Robert Allen Award from the ASCAP Foundation.
