MOTHER AND ONLY DAUGHTER FOUGHT CANCER SEPARATELY — THEN DIED JUST HOURS APART WITHOUT KNOWING THE OTHER WAS GONE

A mother and her only daughter had once spoken about a fear neither of them wanted to face: living in a world where the other was gone. Cibele Fernanda Marchis, 28, and her mother, Maria Elisabete Nogueira, 56, known lovingly as Bia, were both fighting separate battles with cancer while their family desperately hoped they would have more time. In the end, the two women died roughly 10 hours apart, and neither ever learned that the other had passed away.

Cibele died at around 4 p.m. on Thursday, September 24, 2026, at a hospital in Mogi Guaçu, São Paulo, Brazil. Her mother died at approximately 2 a.m. the following morning at another hospital in the same city. What followed was an almost unimaginable sequence of phone calls that forced one family to say goodbye twice before they had even begun processing the first loss.

Their deaths were not the result of the same illness or a shared medical event. Each woman had been fighting her own cancer, enduring different treatments, different complications and different periods of hope and decline. Yet the timing of their deaths brought their stories together in a way their loved ones could never have prepared themselves to experience.

Cibele’s cancer journey had begun with what relatives described as a rare and aggressive form of the disease originating in her adrenal gland. She underwent multiple surgeries and rounds of chemotherapy as doctors tried to control an illness that repeatedly demanded more from her body. At only 28, she was living through medical challenges that would have overwhelmed many people twice her age.

The treatments left visible reminders of everything she had endured. Cibele lived with extensive scars and a colostomy bag, physical changes that could have easily caused illness to dominate every part of her identity. According to those who loved her, however, she refused to allow cancer to become the only thing people saw when they looked at her.

She continued working whenever she could. She traveled, spent time with people she loved and tried to experience life rather than simply wait for the next appointment or medical setback. Cancer was part of her life, but she did not want it to become the definition of her life.

That determination had already been tested severely before her final hospitalization. In December 2025, Cibele developed infections, and her condition became serious enough that doctors reportedly warned the family she might be nearing the end of her life. Her loved ones were forced to confront the possibility that they could lose her months before the September tragedy eventually unfolded.

During that frightening period, Cibele’s mother responded in the way her family remembered most clearly: with devotion. Maria reportedly prayed and fasted for 24 hours, hoping desperately that her daughter would survive the medical crisis. For a mother watching her only child fight for her life, prayer became something she could offer when medicine seemed to be reaching its limits.

Then something happened that gave the family hope. Cibele improved enough to leave the hospital, turning what had seemed like a possible final chapter into another opportunity to live. For Maria, who had spent those frightening hours praying for her daughter, Cibele’s recovery must have felt like precious borrowed time.

Cibele did not waste that time. She continued moving forward despite everything cancer had already taken from her physically, choosing work, travel and moments with people she loved whenever her health allowed. Her life became an example of refusing to wait for perfect circumstances before allowing herself to experience happiness.

She also spoke publicly about parts of her cancer journey on social media. Earlier in 2026, she reflected on the way serious illness had changed her perspective on problems that once might have seemed overwhelming. Facing mortality had apparently reshaped the scale by which she measured everyday worries.

Yet those reflections did not mean Cibele wanted to be known only as “the woman with cancer.” Relatives emphasized that she continued to work, enjoy herself and live as fully as she could. She was a daughter, relative, friend, traveler and young woman before she was a diagnosis.

While Cibele was navigating that difficult road, Maria was facing a frightening medical journey of her own. The 56-year-old initially believed she was dealing with gallstones, something painful but far removed from the diagnosis that eventually came. Doctors ultimately determined that Maria had pancreatic cancer.

The disease reportedly progressed rapidly. As Maria’s condition worsened, her pain became severe enough that she required morphine. The woman who had once prayed through her daughter’s medical crisis was now confronting a serious illness herself.

For the family, the situation was almost unbearably cruel. They were no longer supporting one loved one through cancer but watching both a mother and daughter struggle simultaneously. Every medical update carried the possibility of bad news about either woman.

Maria was admitted to the hospital on September 17. Despite her own illness, Cibele was able to visit her mother during the hospitalization, placing the two women together once more while both were carrying illnesses that threatened their lives. Nobody could have known how little time remained.

Several days later, Cibele’s own condition deteriorated. She also required medical attention, meaning mother and daughter were now both seriously ill at separate hospitals in the same city. Their relatives suddenly found themselves emotionally divided between two hospital rooms and two people they desperately loved.

By September 24, the family knew Maria was gravely ill. That knowledge shaped their expectations when a telephone call arrived that day, because they assumed the news would concern her condition. Instead, the person they were about to lose first was Cibele.

Cibele died at approximately 4 p.m. She was only 28 years old. After surgeries, chemotherapy, infections, scars, a colostomy bag and a determination to continue living beyond her diagnosis, her cancer battle had come to an end.

For Cibele’s cousin and Maria’s nephew, Rowilson Leandro da Costa, the call was devastating. He and the family had been emotionally preparing themselves for news concerning Maria, only to learn that Cibele had died instead. Suddenly they had to begin arranging a farewell for the younger woman while her mother remained critically ill elsewhere.

Rowilson helped organize Cibele’s wake. Family members gathered to confront the reality that the young woman who had once recovered from a crisis doctors feared could be fatal was now truly gone. They said goodbye without knowing that another devastating loss was only hours away.

After returning home from Cibele’s wake, the family received another telephone call. This time, the news concerned Maria. At approximately 2 a.m., around 10 hours after her daughter died, Maria passed away as well.

There was barely time to process one death before the second arrived. A family that had spent the evening mourning a 28-year-old daughter was suddenly mourning her 56-year-old mother too. Grief did not come in separate chapters; it arrived almost all at once.

For Rowilson, there was another heartbreaking responsibility waiting. Cibele’s father had already lost his only daughter only hours earlier. Now someone had to tell him that his wife was gone too.

Rowilson became the person who delivered that news. Within the span of one night, Cibele’s father had gone from having a wife and an only child to grieving both of them. There are few combinations of loss more difficult to comprehend.

Cibele had been the couple’s only daughter. Her death alone would have transformed her father’s life forever, leaving an absence no other child could fill. Maria’s death hours later meant the person who might have stood beside him through that grief was gone too.

The timing carried another detail that relatives found especially emotional. Cibele and Maria had reportedly talked in the past about how neither wanted to remain alive if the other died. Each feared the pain of having to live through the loss of the other.

Those conversations could never have predicted exactly what would happen. Yet in an extraordinary and heartbreaking coincidence, mother and daughter died so close together that neither had to receive the news they had feared. Neither woman consciously experienced the moment of being told the other was gone.

When Cibele died, Maria was reportedly already sedated. She never learned that her only daughter had died before her. Whatever awareness she had in her final hours, she was spared that devastating news.

Cibele, meanwhile, died first and therefore never learned that her mother would pass away only hours later. The woman whose mother had once prayed and fasted for 24 hours in hopes of keeping her alive never had to hear that Bia’s own cancer battle had ended. Their family was left to carry both truths for them.

There is something almost impossible to process about the timing. Ten hours can pass during a workday, an overnight journey or a long hospital wait, yet for this family that short span separated two deaths that changed everything. By the time morning arrived, both women were gone.

The illnesses that took them were separate. Cibele’s cancer had reportedly originated in her adrenal gland, while Maria had been diagnosed with pancreatic cancer after initially believing she was suffering from gallstones. Their deaths were medically distinct even though grief would forever connect them.

Their journeys were also different. Cibele had endured a longer series of surgeries, chemotherapy and complications while repeatedly trying to return to ordinary life. Maria’s cancer reportedly progressed quickly, taking her from an unexpected diagnosis to severe pain and hospitalization.

Yet throughout both stories, the bond between mother and daughter remained impossible to overlook. When Cibele became dangerously ill months earlier, Maria prayed and fasted for her survival. When Maria later entered the hospital, Cibele went to visit her despite facing serious health challenges of her own.

That visit now carries a meaning nobody could have understood at the time. It was not simply a sick daughter checking on her sick mother. It became one of the final opportunities for two women whose lives were approaching their endings almost simultaneously to be connected in person.

Their family will likely remember details from those final days differently. Some may remember hospital calls, others may remember the wake, and others may remember the shock of learning that Maria had died before Cibele’s funeral arrangements had even fully settled into reality. Trauma often preserves moments people desperately wish they could forget.

But Cibele’s family has also emphasized the life she lived before those final hours. Cancer changed her body, but it did not eliminate her desire to work, travel and enjoy the people around her. Even after facing a medical crisis in December, she returned to living rather than simply existing.

Her scars told one story. Her colostomy bag told another part of the medical reality she carried. Yet neither told the complete story of Cibele Fernanda Marchis.

She wanted to be more than what cancer had done to her. That desire mattered because serious illness can sometimes consume a person’s public identity, reducing years of personality, relationships and experiences to a diagnosis. Cibele resisted that reduction.

She continued making plans and creating memories. She allowed herself to travel and enjoy life even though there was no guarantee about how much time she had left. Those choices now give her loved ones memories that exist beyond hospitals and treatment rooms.

Maria deserves the same kind of remembrance. Loved ones described her as loving, joyful and generous, someone deeply devoted to the people around her. Her identity was larger than the pancreatic cancer that ultimately took her life.

Her response to Cibele’s December crisis perhaps captures that devotion most powerfully. Faced with the possibility of losing her only daughter, she prayed and fasted for an entire day. Whether viewed through faith, maternal love or both, the act showed how desperately she wanted her daughter to remain alive.

Cibele did survive that crisis. She left the hospital and received additional months with her family, months in which she could work, travel and continue living on her own terms. Maria’s prayer became part of the family story surrounding that unexpected period of recovery.

No one could have known that Maria herself would soon need the same hope. Her diagnosis changed the family’s situation dramatically because the mother who had been supporting a sick daughter was now seriously ill too. Suddenly there was no healthy half of the mother-daughter relationship standing outside the hospital bed.

Both needed care. Both faced pain. Both were moving toward outcomes their family desperately wanted to prevent.

The final week compressed those fears into a devastating reality. Maria entered the hospital on September 17, and Cibele visited her while she could. Days later, Cibele’s own body weakened enough that she required medical care too.

Then came September 24. A phone rang, and relatives thought it would bring an update about Maria. Instead, they learned that Cibele was dead.

Then came the early hours of September 25. Another phone rang after the family had already been saying goodbye to Cibele. This time, Maria was gone.

For Cibele’s father, those two calls represented the collapse of the family life he had known. His only child was dead. His wife was dead.

There would be no wife beside him to mourn their daughter. There would be no daughter beside him to mourn her mother. He had to face both absences simultaneously.

Eventually, Cibele and Maria were buried together in a joint funeral. Family and friends gathered not for one farewell but two, mourning a mother and daughter whose lives had ended within roughly 10 hours. Their separate cancer battles had led them to one final resting place together.

A joint funeral can make loss visible in a way words cannot. Two lives, two sets of memories and two relationships with everyone present must be acknowledged at once. For this family, there was no time to finish grieving one woman before beginning to grieve the other.

Yet perhaps the funeral also reflected the closeness relatives had described between them. Mother and daughter had feared separation so deeply that they had talked about not wanting to experience life after the other’s death. In the end, even their final farewell took place together.

Their story is not remarkable because cancer took two members of one family; sadly, many families endure multiple diagnoses over time. What makes the circumstances so difficult to absorb is the extraordinary closeness of the timing and the emotional history surrounding their bond. The daughter died in the afternoon, and before the next morning had fully begun, her mother was gone too.

Neither knew. Maria did not wake to hear that Cibele had died. Cibele never had to discover that her mother’s final hours were approaching.

That fact may offer the family a complicated kind of comfort amid overwhelming grief. They themselves had to endure both deaths, but the two women they loved were spared the particular heartbreak each had once feared. Neither had to look into a world and consciously understand that the other was no longer in it.

For everyone left behind, however, the pain is doubled. There are now two empty places at family gatherings, two birthdays carrying absence and two lives to remember. Every story about one woman may naturally lead to a memory of the other.

There will be memories of Cibele working despite everything she endured. There will be stories of her traveling, living with scars and a colostomy bag without allowing those realities to dictate whether she could still enjoy herself. There will be memories of a 28-year-old woman determined to remain more than her illness.

There will also be memories of Maria’s joy and generosity. Loved ones will remember the mother who devoted herself to those around her and the woman who responded to her daughter’s medical crisis with prayer and fasting. Those memories belong to the family in a way no medical record ever could.

Cancer explains why Cibele and Maria died. It does not explain who they were. Their family, friends and the lives they touched hold that much larger story.

Cibele’s own words and actions suggest she understood something about that distinction. Serious illness had changed her perspective on life’s problems, but she still chose to participate in life instead of retreating from it completely. She could acknowledge cancer without surrendering her entire identity to it.

That may be one of the most enduring parts of her story. She did not get to choose how long she would live, but she repeatedly tried to choose how she would use the time that remained. Work, travel, relationships and ordinary enjoyment remained worth pursuing even when her body carried visible evidence of everything she had survived.

Maria’s story leaves a similarly powerful image. A mother who once spent 24 hours praying and fasting for her daughter eventually found herself in a hospital fighting for her own life. Even then, her bond with Cibele remained at the center of the family’s final memories.

Their deaths arrived only hours apart, but their relationship had been built across 28 years. There were decades of ordinary mother-and-daughter moments before cancer entered their lives, countless conversations and memories the public will never know. Those years matter more than the 10 hours that now make their story so striking.

For Cibele’s father, Rowilson and the rest of the family, grief will continue long after attention surrounding the unusual timing fades. They must learn how to live with a silence left by two people instead of one. They must carry the memories of mother and daughter forward together.

Perhaps one day the shock of those two phone calls will become less immediate. Perhaps the memory of hospitals and cancer treatments will slowly make more room for memories of travel, laughter, family gatherings and ordinary conversations. Grief does not erase the final days, but with time it can sometimes allow the rest of a person’s life to become visible again.

Cibele was more than a 28-year-old cancer patient. Maria was more than a 56-year-old woman with pancreatic cancer. They were mother and daughter, deeply connected in life and, through an extraordinary and heartbreaking turn of events, separated from that life only hours apart.

They once reportedly feared the idea of one having to live after losing the other. Neither woman ultimately had to receive that news, even though the family around them was forced to endure both losses. It is one of the most haunting details in a story already filled with grief.

Cibele died first, after spending years refusing to let cancer become the entirety of who she was. Maria followed approximately 10 hours later, after her own rapidly progressing illness had brought her to the hospital. The mother who had once prayed for her daughter’s survival and the daughter who had visited her sick mother were gone before another full day had passed.

Their family then brought them together one final time. Cibele Fernanda Marchis and Maria Elisabete “Bia” Nogueira were laid to rest in a joint funeral, surrounded by people grieving two lives at once. Mother and daughter had fought separate battles, but their final goodbye became one.

Their story will inevitably be remembered for the extraordinary timing of their deaths. But the 10 hours between them should not overshadow the 28 years they had together, the devotion Maria showed her only daughter, or the determination Cibele showed in continuing to live despite everything cancer demanded from her. In the end, those are the memories that reveal why losing both women at once has left such an enormous emptiness behind.
