She was 54.
Her death was confirmed by the official Mexican news agency Notimex and the TV stations for which she worked, Televisa and TV Azteca.
CNN reached out to her publicist and the agency that represents her but hasn't received a response.
The actress revealed in August 2016 that doctors discovered cancerous tissue in her abdomen. Her cancer entered remission in 2017 but returned sometime this year.
She is survived by her husband, Lorenzo Lazo, and 14-year-old daughter, Constanza.
A photo of Gonzalez and her daughter posted to her official Instagram on Thursday amassed more than 14,000 comments from celebrity friends and fans.
"Goodbye beautiful soul! What an honor to have met you and share spaces!" Mexican actress Michelle Renaud commented.
Morning show host Andrea Legarreta called Gonzalez a "loving warrior" and an example for women.
Best known for her role in the soap "Salomé," Gonzalez continued to work up until her death, most recently as a judge on the Mexican reality show "This Is My Style."
An account for that show mourned Gonzalez in a post.
