Mother and daughter die of cancer within ten hours in Brazil

In the city of Mogi Guaçu, Brazil, a family experienced a tragic loss as a mother and her daughter passed away from cancer within a ten-hour interval. The daughter, 28-year-old digital marketing professional Cibele Marchis, died at approximately 16:00 on Thursday. Her mother, 56-year-old Maria Elisabete Nogueira, died at 02:00 the following Friday while hospitalized at a separate facility in the same city.

Cibele Marchis had been battling a rare and aggressive form of adrenal cancer since her 2024 diagnosis. Despite undergoing multiple surgeries and chemotherapy, her condition worsened significantly in December 2025 due to complications from infections. Family members noted that the two women provided each other with significant emotional support throughout their illnesses, with the mother reportedly fasting and praying for her daughter's recovery during the most difficult phases of the treatment. The deaths have shocked the local community and received widespread media coverage, highlighting the profound impact of the simultaneous loss.
