Drawing from perspectives of both bioethics and anthropology, this article explores how the boundaries between personal and relational privacy are negotiated by patients and practitioners in the context of an emerging domain of cancer genetics in Brazil. It reflects on the place of informed consent in the history of bioethics in North America in contrast to the development of bioethics in Brazil and the particular social cultural context in which consent is sought in Brazilian public health care. Making use of empirical research with families and individuals receiving genetic counselling related to increased genetic risk for cancer, in genetic clinics in southern Brazil, it examines how informed consent is linked to the necessary movement between personal and relational privacy. The paper illustrates the value of a particular tool known as a 'sociogram' to examine the complex interpersonal dynamics that arise in negotiating informed consent at the interface between the family and the individual in Brazil. The paper, therefore, points to the scope of further interdisciplinary exchanges between anthropology and bioethics, confronting the new challenges that arise in the context of medical genetics in developing country.

Two issues are particularly relevant when considering the
specific bioethical challenges raised by developments in genetic
medicine: informed consent and privacy.
The first concerns the challenges of informed consent
given the way that much medical genetics operates at a boundary,
often difficult to separate, between health care and research
(Hallowell 2009; Hallowell et al. 2010). In regular health care
contexts, the patient brings a medical need to be evaluated and
treated by professionals, while in a research scenario, the
researcher offers a possibility of participation in a project. In
genetic medicine, health care necessities are entangled with
research possibilities and potentials. This may create problems
for professionals and patients/participants with respect to
issues such as consent. Patients/participants may find it difficult
to understand the difference between research and health as
separate fields of activity (Bosk 2002). These issues may be
particularly acute in developing and low and middle income
country contexts, such as in Latin American, where public
health is precarious for many people in ways that often make
participation in research a means of accessing basic health
care resources. This is an expression of ethical variability
of institutional or transnational research cultures, particularly
in the context of the outsourcing of clinical trial research
(Petryna 2009).
The second issue relates to privacy. The most common way
to understand privacy and consent is at the individual level.
Developments in medical genetics extend these concepts
beyond the individual, because related persons may become
involved, as they are themselves at genetic risk or in a situation
to benefit from familial information about potential genetic
risk. In this new context, protection of personal sensitive data
takes on a new (expanded) meaning of relational privacy
(Ursin 2008). As a result, informed consent may only be
achieved when addressed within the wider scope of the family
(Hallowell 1999).
This paper makes use of approaches within the disciplines
of bioethics and anthropology to explore the challenges of
informed consent and privacy in the context of the emerging
domain of cancer genetics in Brazil. It pays particular attention
to how the boundaries between personal and relational privacy
are negotiated by patients and practitioners. First, it reflects on
the place of informed consent in the history of bioethics in
North America, in contrast to the development of bioethics in
Brazil; before outlining the particular social cultural context in
which consent is sought in Brazilian public health care
settings. Making use of empirical research with families and
individuals receiving genetic counselling related to genetic
risk for cancer in genetic clinics in southern Brazil, it
illustrates how informed consent is linked to the necessary
movement between personal and relational privacy. This is further
explored in relation to the use of a particular tool, known as a
sociogram, to examine the complex interpersonal dynamics
that arise when negotiating informed consent at the interface
between the family and the individual in Brazil.
The historical evolution of informed consent in North
America and beyond
The theoretical basis for the informed consent rationale has
emerged, especially in the USA, on a contractualist basis
(Beauchamp and Childress 1978). In that context, the
professional has a duty to inform and to respect the voluntariness of
another capable person. This person, after being properly
informed, chooses to accept or reject the offer made to him/her,
exercising his/her autonomy. In this principialist perspective,
the relationship between the professional and the other person
involved is based on duties (Faden and Beauchamp 1986).
Seen in this way, the consent process has certain
preconditions. These include the ability to understand and decide
voluntarily. The process also comprises two components:
information and consent itself, as in (for example) an authorization
for the proposed action (Beauchamp and Faden 1995). The
professional has a duty to inform while the other person
involved must decide whether to allow the proposed action.
Signing of the informed consent form would be understood
as the proof that the process was properly undertaken, based
on the assumption that the person was able to understand and
decide, after being properly informed.
Many projects have been conducted to study the
relationship between the capacity to provide informed consent, age
and level of education. Studies have shown that it is not only
adults who are capable of doing so but also teenagers and the
elderly are able to decide what is in their best interest. The
legal standard for capacity should not be confused with the
ability in itself, which is dependent on psychological and
moral development (Raymundo and Goldim 2008). Similarly, it is
notable that many research participants, almost 50 %, sign a
consent form without having adequate understanding of what
is being proposed (Goldim et al. 2007).
Nevertheless, from within the social sciences, there has
been a strong critique of the principle o (...truncated)
