The Psychosocial Impact of Screening for
Hereditary Cancers
By Michelle S. Wasserman, PhD
As we forge ahead through the 21st century, scientific
advances, including the human genome project, have
created increasing potential for prevention of illness
such as cancer. As a result, our ability to determine
who may be at increased risk for diseases such as cancer
is among those important advances. Genetic screening for
inherited cancer risk is a simple test in its execution,
but this quick blood draw holds extremely powerful
information for individuals and their families regarding
health and illness across the lifespan. Indeed, the
psychosocial issues that arise from genetic testing
interact with elements of our personality and cognitive
capacity, affect our relationships with ourselves and
with others, and strike at the core of our very
identity.
Decision Making
• Who should pursue screening and why? Before
you pursue testing, you should first consider if the
test would be beneficial to you. Cancer patients and
survivors are often first to consider genetic testing
and in some cases, test results may be used to help plan
cancer treatment. Unaffected relatives of cancer
patients and those with suspected or confirmed family
history of cancer are also considered for testing. For
example, if you are a 30 year old woman with a mother
and maternal aunt who have had breast cancer and a
maternal grandmother with ovarian cancer, it is possible
that the cancer that runs throughout your family is
inherited. Instead of spending nights worrying about
whether or not you have inherited this cancer, genetic
screening for BRCA1/2 may help alleviate some of this
uncertainty and in turn, may help you determine a course
of action to improve your health status. In addition,
determining your mutation status may enable your
physician to individually tailor preventive care.
• Limitations of testing: Despite the benefits,
the choice to not pursue testing is just as viable an
option as choosing to test and it is important to keep
in mind that genetic screening for cancer-causing
mutations is not without limitations. Although genetic
screening can help individuals learn about the presence
of genetic mutations, these tests do not test for cancer
itself, and merely offer a better understanding of the
risk of developing cancer in the future. That is,
testing does not determine if you currently have a
cancer condition, does not explain how or why mutations
occur and does not determine disease onset, course, or
severity. Perhaps most importantly, even if no mutations
are detected by the screening procedure, it does not
mean that you are free from cancer risk. Cancer is an
illness caused by a confluence of mutations in multiple
genes and environmental factors and your may continue to
be at risk for developing a sporadic cancer condition.
Finally, screening is costly and availability of genetic
counselors and testing centers may be limited for some
people. However, as many Ashkenazi Jews undergo testing
for only the founder mutations (“Ashkenazi panel”), the
cost to this population may be lower.
• Concerns about discrimination: Even while
weighing the benefits and limitations of genetic
screening, you may also find yourself worrying about
both health insurance and life insurance discrimination
and the potential misuse of information in other ways.
In the United States, the federal Genetic Information
Nondiscrimination Act of 2008 (GINA) protects
individuals undergoing genetic testing and prohibits
insurers from denying insurance or raising premium or
contribution rates on the basis of genetic information.
One way to manage some of your concerns about life
insurance discrimination is to purchase life insurance
before undergoing genetic testing, so as to eliminate
the possibility of being denied a policy. Also, although
you may be concerned about the potential for workplace
discrimination, it is important to note that GINA also
covers protection from such discrimination and even
before this law passed there were no documented cases of
such prejudice reported.
• Cultural differences: Cultural, ethnic,
and/or sociodemographic factors also influence the
degree to which individuals choose to pursue testing.
For example, in a recent study, African-American women
who declined genetic counseling or testing reported
greater concerns about stigmatization and familial
guilt. Other data demonstrated that among Ashkenazi
Jewish women, those with strong Jewish cultural identity
overestimated their perceived risk of developing breast
cancer even after receiving counseling and those with
greater religious identity were more interested in
pursuing testing after receiving genetic counseling.
As you consider testing: Psychological, emotional and
social implications
• Normal Anxiety and Distress: Most likely, if
you have a family history of cancer, you already
experience a significant level of distress when thinking
about the possibility of your having cancer in the
future. Anyone would be anxious if given an opportunity
to learn if their risk for a deadly illness is higher
than average. Recent research indicates that in
individuals seeking genetic counseling and testing for a
variety of cancer diagnoses, high levels of anxiety were
reported and were particularly high for those with
painful memories of how the illness had affected close
family members. Worrying in this way may actually be
useful in that it serves as a way to rehearse or prepare
for receiving test results. In fact, if you experience
no anxiety about testing, research demonstrates that you
may be more at risk for greater distress after receiving
test results.
• Anxiety about managing results: In thinking
about whether to pursue testing, you will likely have
concerns about how others will react. It is also
important to think about what a “positive” finding may
mean for you personally. Will it affect your
relationships with others, choice of employment, plans
for biological children, economic status? In essence,
what will you do with the test result? Research has
supported the idea that people are sometimes reluctant
to pursue testing when they don’t believe that the
result will change their current screening regimen. For
example, if colon cancer runs in your family and you
already have a yearly colonoscopy, you might wonder if
there would be a benefit to learning your genetic status
regarding HNPCC/Lynch syndrome. Of course, the answer
depends on what else you might do with this information
and how your family and future generations might derive
benefit from knowing your genetic status.
• Risk Perception: Interest in pursuing genetic
counseling and testing is often informed by an
individual’s belief that his/her level of vulnerability
to disease is due to a hereditary predisposition in
his/her family. Research has shown that in general, for
example, women overestimate their risk for breast cancer
and some individuals (especially those with an extensive
family history of cancer) are so convinced that cancer
is inevitable, that they believe it is not a question of
if they develop cancer but rather when. In many of these
cases, people hold the false belief that genetics are
responsible for determining their breast/ovarian cancer
risk, but the reality is that only 5-10% of such cancers
are hereditary. Before pursuing testing, it may be
helpful for you to think about your own risk perception
– that is, how likely is it that you will develop a
specific cancer, either in the next year, five years, or
over your lifetime – and speak to a genetic counselor
about how realistic that assessment is. It may also help
you to think about how much you believe genetics play a
role in your estimate of risk to determine whether
learning about your actual genetic risk will provide you
with helpful information.
• Communication with Family Members: Before
pursuing testing, you may want to consider the kinds of
relationships you have with other members of your
family. Does your family share intimate medical details
freely or are there secrets between family members?
While learning of the presence of a genetic mutation in
a family can often bring family members closer together,
there is also the potential for miscommunication and
hurt feelings between family members. Concerns about how
the results might affect your family are normal and
should be thoroughly considered early on in the
counseling/testing process.
• Biological family: Although we hope that
family members will provide the necessary love and
support for individuals who choose to embark on the
genetic screening process, deciding to pursue genetic
testing also has the potential to foster resentments and
general tension within families. Therefore, determining
who you can and want to talk to about your decision to
test is also important. Often, when genetic mutations
are found in one family member, additional family
members are then forced to think about their own desire
to pursue testing. Siblings who are not interested in
knowing the family’s genetic status may feel that such
information was forced upon them. Older family members
may not understand why testing is important or how
technology plays a role in the private health matters of
the family. Similarly, your parents may be resistant to
learning more about your genetic makeup, as they may
fear that you will blame them for a genetic mutation
and/or they may harbor their own guilt for doing so.
Finally, children may not understand the details of a
genetic test and/or may believe that finding a mutation
means their parent is sick right now. You may consider
keeping the information to yourself, but if you’re
planning prophylactic measures, it may be difficult to
keep the truth from close family members.
• Spouse/significant others: Thinking about how
a partner may respond to the presence of a genetic
mutation is crucial for many people. Because the
presence of a genetic mutation may impact an
individual’s desire to have biological children for fear
of passing on a mutation and/or may influence the time
frame in which children are conceived (i.e., prior to
pursuing prophylactic surgery), your age, stage of life,
and whether or not you have children are important
factors which play a role in how your partner may react.
For example, if you already have children, your partner
may react differently than if you are someone who has
recently embarked on a new relationship with someone for
whom having biological children is important.
• Coping/Information Processing Style: Genetic
screening for cancer requires a willingness to attend to
and cope with a large body of abstract and complex
information which is potentially threatening to one’s
personal bodily integrity. When dealing with
health-related information, personality variables can
greatly impact the extent of an individual’s emotional
response and coping. One such personality variable
involves the degree to which individuals are “monitors,”
who tend to focus on threatening aspects of the
information provided, focus on negative outcomes, and
continue to somewhat compulsively search for new
information that they hope will allay their fears, or “blunters,”
who intuitively shield themselves from the threat
component of information provided to them. Research has
demonstrated that for women awaiting BRCA1/2 results,
those who are high “monitors” have greater levels of
anxiety, more intrusive thoughts about cancer, and
higher levels of general distress.
Receiving results: Psychological, social and emotional
considerations
Should you decide to pursue testing, you will
likely experience a range of different emotions
throughout the process.
• Waiting for your results: Depending on where
you live, you may be waiting for your results anywhere
from several weeks to several months, or even longer.
This period of time can be very challenging. You have
likely made a firm decision to be proactive about your
health, weighed the pros and cons of testing, and are
now having to manage the uncertainty of a lengthy
waiting period. The best thing to do during this period
of time is to be optimistic, focus on other aspects of
your life, and to take good care of yourself. It is not
useful to dwell on whether or not testing was a good
idea and/or to worry about the test result. Time will
pass and the results will eventually reveal themselves.
• Positive result – learning you have a mutation:
It is common to experience increased anxiety
after receiving a “positive” result, because you are
suddenly aware of your increased risk. In fact, you may
begin to wonder if you or others will define yourself by
your genetic status. You may feel increased stress over
having to decide the best cancer prevention strategy for
yourself. Depression and sadness are also somewhat
common, especially in cases where an individual has lost
a close family member to cancer in the past. Some
speculate that resolution of grief is helped by being
able to differentiate oneself from the person who has
died, and this is made more difficult by linking one’s
relative’s cancer with oneself. That said, you may also
experience relief from knowing your risk status and can
now increase your cancer surveillance efforts or take
steps to reduce your risk. In general, most people cope
well in the face of learning of their increased risk.
Talking to a genetic counselor, psychologist, or
oncologist may help provide clarity about many of these
issues.
• Negative result – learning you do not have a mutation:
Although somewhat counterintuitive, learning
that you do not have a genetic mutation may also
increase your level of distress. Many people have looked
for the testing to provide an explanation about why
there is so much cancer in their family and in the
absence of a mutation they are left feeling more
confused. Others may feel guilty if they do not have a
mutation while others in their family do – a type of
“survivor” guilt. Most often however, when individual
test results are negative, and there is a known mutation
in the family, individuals feel a huge sense of relief.
Regardless, it is important to remember that even with a
negative test result you still remain at risk for cancer
– the same amount as in the general population.
• Unclear results – variants of unknown/uncertain
significance: In some situations, test results
are neither positive nor negative, but rather, identify
a gene alteration that hasn’t been seen in other
families and/or there isn’t enough information about the
mutation to know whether it causes an increased risk of
cancer. This result may also increase confusion and
anxiety about cancer risk and may leave you feeling
frustrated over the lack of useful information and the
current state of medical science.
• Responses from family to presence of a mutation:
After receiving results indicating the presence
of a genetic mutation, even if all family members are
not aware of their genetic status, the existence of a
mutation in the family is now “known” as a certainty.
Some family members may be concerned about
confidentiality and may require you to be particularly
guarded with this information. As a result, your
relationships with them may change. Alternatively,
discovering the presence of a mutation may deepen ties
to other affected family members as each of you may feel
better able to support each other in making decisions
regarding your genetic status.
Spouses and significant others may also be impacted by
these results, as they may be concerned about what your
genetic status may mean for them. In essence, the same
ideas that concern you about your life plan may also be
of concern to them: career choices, pursuing
relationships, having children. If you already have
children, they may also be concerned about your having
passed the same mutation to your children and if so, may
feel resentment toward you and other of your biological
relatives for this situation.
As genetic screening for hereditary cancer becomes more
available and widespread, our understanding of how this
process impacts individuals, family life, and society
will also likely improve. At present, research indicates
that although there are many psychosocial issues to
consider, the benefits of discovering one’s genetic
status are quite significant and have the potential to
reduce mortality over the long term. If you are
considering pursuing genetic screening, you should only
do so after consulting with a genetic counselor who can
help you make an informed decision. Speaking to a
psychologist or other mental health professional, who
has knowledge of the genetic screening process, may also
help you further explore these psychosocial issues in
more detail. In addition, for those pursuing testing for
BRCA1/2, Facing Our Risk of Cancer Empowered (FORCE) is
a wonderful organization which provides support for
those who have increased genetic risk for breast and
ovarian cancer. More information about their
organization can be found on their website.
