. A leading actress who combined her craft with comedy, she left a legacy in both film and television.
While the network’s farewell messages did not detail the medical circumstances of her death, reports attributed to journalist María Luisa Valdés Doria, known as Magüicha, stated that the actress had been facing a cancer diagnosis. No details or causes of the passing were revealed in the announcements. To date, the official cause of death remains unconfirmed, and no details have been released about treatments or complications she may have faced in her final years.
Four decades from children’s shows to comedy and telenovelas
Delgado began her television career in 1984 on the program “El tesoro del saber”, where she played Marilú, and appeared in children’s programming such as “Odisea Burbujas”. Her entry into the industry came in the 1980s when producer Enrique Segoviano cast her in various family-oriented productions.
Her most recurring character was “Alz”, a tender and forgetful elderly woman who starred in comedy scenes alongside Derbez as “Heimer”; her performance in that role became one of the most remembered in Mexican comedy. The news of her death brought her characters back to the memory of viewers, from the tenderness of “Odisea Burbujas” to the sketches of “Derbez en cuando” and “Cero en conducta”, while her collaboration in “Derbez en cuando” had reached new generations of viewers. She also played “La Abuela” in “Cero en conducta” and appeared in “Humor es… los Comediantes”, “La casa de la risa”, and the series “¿Tú crees?”, one of her final projects. In drama, she joined the cast of more than 15 telenovelas, including “Amorcito corazón”, “La vecina”, “El diario de Daniela”, “Serafín”, “Zacatillo”, “Un lugar en tu corazón”, “Enamorándome de Ramón”, “Ringo”, “Médicos, línea de vida”, “De que te quiero, te quiero”, and “Monteverde”.
Cancer reported but not officially confirmed as cause of death
The posts announcing her death focused on condolences and tributes to her legacy, but none included a medical explanation. The cancer version was attributed to Magüicha, though no official confirmation exists to establish it as the direct cause of her passing. The type of cancer, how long she had been under medical attention, and any treatments she received remain unknown, and it was not reported whether the illness led to complications in her final days.

Born on March 18, 1949, in Monterrey, Nuevo León, Delgado had previously explained in interviews that she continued working due to economic needs and medical expenses, and to support her son, who was born prematurely and has a hearing disability, according to reports in Milenio. She was part of Mexican television for several decades, particularly in family-oriented productions from the 1980s onward, and although she had a reduced on-screen presence in her final years, she remained active and continued working on artistic projects. Her most recent project was the telenovela “Sabor a ti”, produced by Lucero Sánchez and still on air at the time of her death.
