Family requests to conceal a diagnosis place the clinician at the intersection of ethics, communication, and patient autonomy. A recent case shared by an oncologist highlights how common and complex these situations remain in clinical practice.

“Patient does not know the diagnosis. Family wants to speak with the doctor first.” The note, written on Post-it, was received by Deborah Cotrim, MD, oncologist from Hospital Oncovida, Montes Claros, Brazil. She shared the experience on Instagram, where it drew more than 400 comments and prompted widespread debate.

In her post, Cotrim explained that such requests occur often, particularly among older adults. Families often act out of fear of how a loved one may respond to a serious illness. She noted that although there are no simple answers, one principle remains clear: There is no place for lies in medicine. “I learned, especially in oncology, that there are pains that do not lessen when hidden. They only became more solitary,” she wrote.

She added that the post resonated because it offered no simple answer. “This is a delicate topic, full of nuances, where there are no ready-made formulas, only the constant challenge of acting with ethics, empathy, and humanity,” she explained.

Patient Rights

In an interview with Medscape’s Portuguese edition, she clarified when withholding diagnostic information was acceptable. Cotrim said that the first step is to listen to and support the family. “I explain that, from an ethical and human standpoint, the patient has the right to know their own condition,” she said.

She emphasized that information can be given gradually and in moderation, respecting the patient’s emotional pace. “Not everyone wants to know all the details immediately, and that must also be respected. However, if the patient directly asks for a diagnosis, the doctor has a duty to answer honestly. But lying is never an option for me, based on how I practice and on ethical grounds,” she said.

Cotrim noted that such requests often arise “from love and fear of causing suffering” but also reflect an ongoing cultural difficulty in discussing serious illness, death, and vulnerability.

She referred to the concept of “therapeutic privilege,” which allows physicians, in rare cases, to withhold, postpone, or modulate information if there is a clear risk of serious physical or emotional harm to the patient. This approach should be exceptional and temporary, and never a rule. One example involves patients with severe psychiatric disorders, such as severe anxiety with disorganized thinking or suicidal ideation.

Cotrim recalled an instance in which disclosure was delayed due to severe anxiety. “I only communicated after clinical stabilization and psychiatric support,” she said.

Ethical Limits

Although there are no “magic formulas” for this type of situation, there is a Medical Code of Ethics. The rule is clear: The patient has the right to know the diagnosis and treatment. This duty of the doctor is based on respect for the autonomy and dignity of the person: “[The patient] has the right to participate in decisions about their own health,” said João Roberto Oba, physician specialist in forensic medicine and medical expertise, professor from the Faculdade Santa Marcelina in São Paulo.

He explained that withholding information is allowed only when disclosure may cause harm. In such cases, information should be shared with a legal representative. Even then, the limits apply. “Omission does not authorize lying, permanent concealment, or automatic submission to the family’s wishes,” he said. Decisions must be proportional, justified, and documented in the medical records.

Fabiana Gomes de Campos, MD, and president of the Medical Ethics Committee from A.C. Camargo Cancer Center, São Paulo, Brazil, reinforced this position. “If the patient asks directly, there is no way around it. The physician cannot lie,” she said.

In cases of cognitive impairment, such as dementia, communication should match the patient’s level of understanding, and decisions may involve legal representatives. 

Oba said, “The Statute of Persons with Disabilities establishes that disability, in itself, does not affect full legal capacity, and guardianship is an exceptional measure. Thus, the physician must concretely assess the patient’s capacity for understanding and decision-making, avoiding paternalistic stances or undue generalizations.” 

Parents play a vital role in pediatric care, but clinicians should involve adolescents when appropriate. “If they ask relevant questions about their health condition, a strong relationship among parents, the patient, and the medical team is essential. We must find the best path for everyone,” Gomes said.

Experts have also highlighted the potential legal and ethical consequences. “If the medical team omits or lies, even at the family’s request, it may constitute a very serious ethical violation and even a crime,” Gomes said.

Authors of Bioética para profissionais da saúde argued that even with good intentions, family members can sometimes prevent patients from making final choices about how they want to spend their last moments. They added that a patient’s right to decide about their own life should be set aside only for compelling reasons, and those reasons should be clearly explained and justified.

Disease Perception

Tiago Kenji Takahashi, MD, oncologist from the Hospital Santa Paula, São Paulo, Brazil, noted that public understanding of cancer has improved. People are now more informed and understand that the disease can be treated, with possibilities of cure, and a return to normal life after treatment.

“Today, with all the campaigns we’ve been doing, with the color-coded months like Pink October and Blue November, cancer is demystified and information is more accessible,” says the doctor. “In fact, patients often already see their test results on apps.”

Takahashi supported informing patients directly, even if delivered in stages. “Not everything needs to be said at the first visit. We can break communication into steps, but the patient needs to be informed,” he said.

He warned that withholding information could damage trust. “If the patient discovers there was omission, the relationship is severely compromised. Treatment involves a multidisciplinary team, so silence is almost impossible.”

Clinicians noted that patients often sense when something is wrong. Changes in routine and emerging symptoms may signal an underlying disease. “Many fear that the patient will give up on life or become too frightened to continue treatment. In serious illness, the whole family is affected, but the patient still has that right,” Gomes said.

Cotrim said the discussion resonated because it addressed “something human and universal, which is the fear of suffering and the desire to protect those we love.” She added that even without simple answers, clinicians should aim to balance truth, treatment, and respect for patient autonomy.
