Introduction
Everybody carries some genes that are protective against cancer; these genes correct any DNA damage that occurs naturally: when cells divide. However, some genes are not altered and when they are inherited they raise the risk of developing cancer.

History of Genetic screening
2008 brought a slew of internet offerings regarding DNA-based tests pitched to wealthy customers. Testing babies for phenylketonuria started more than a century ago. Phenylketonuria is an inborn malfunction of metabolism: amino acids accumulate in the blood tissue resulting in retardation. Blood is obtained from the infant’s heel and used for testing in the lab. In case the child is found to have Phenylketonuria, strict dietary measures are taken to preserve the brain function, this is among the first genetic tests, it made treatment of the diseases easier, it did not have any possibility of mistakes, and all people can be

Most aspects of genetic testing often end up in ethical dilemmas; these aspects are the limitations that are present in genetic testing, unwanted results after a genetic test, existence of false positive or negative results and potential consequences. Recently, medical ethics has become an issue of great concern in medical studies. Medical technologies like genetic testing and cancer screening have caused bioethical dilemmas to be experienced by physicians. Every patient has the right to access of full information regarding their medical condition. This ethical dilemma revolves around the voluntary informed consent of the patient and the harmonious relationship between benefit and risk to the patient. A lot of questions are asked concerning breast cancer screening. Ethical principles in breast cancer screening, aim at reducing unnecessary harm to the participating
The Human Genome Project is the largest scientific endeavor undertaken since the Manhattan Project, and, as with the Manhattan Project, the completion of the Human Genome Project has brought to surface many moral and ethical issues concerning the use of the knowledge gained from the project. Although genetic tests for certain diseases have been available for 15 years (Ridley, 1999), the completion of the Human Genome Project will certainly lead to an exponential increase in the number of genetic tests available. Therefore, before genetic testing becomes a routine part of a visit to a doctor's office, the two main questions at the heart of the controversy surrounding genetic testing must be
Heredity also plays a role in the development of cancer. If a person’s relatives have a history of cancer, then that person has a higher risk of developing cancer. Genetic variations, particularly those influencing how the body responds to carcinogens, may create a greater vulnerability to cancer.
It is patients’ right to opt for genetic testing on their own DNA, although they are accepting a great risk by doing so.
What are the most serious genetic diseases and what are the pros and cons of genetic testing?
Genetic testing has brought about many changes in the way many couples look at conceiving and raising families. Through genetic testing you are able to screen for the increased chance that a fetus may have one of many congenital disorders, or even identify gene changes that are responsible for a disease that has already been diagnosed (Genetic Testing, March 2015). Unfortunately genetic testing is not always exact, in some cases giving parents false negatives or false positive results. Even if the results are accurate, there is the burden of knowledge once you know the results indicate a genetic abnormality such as Down’s syndrome. While caring for a 2 year old male patient with developmental delays and anotia, I learned that genetic testing had been started but never completed on the child. Genetic testing could help to identify genetic disorders that led to the child’s developmental delays and possible future disorders that may develop. The ethical dilemma I will be discussing to the ANA Ethical dilemma of the impact of informed consent of genetic testing on children for adult onset diseases and disorders.
In chapter four of her book Genetic Dilemmas, Dena Davis asserts that it is unethical for parents to subject their children to genetic testing for the markers of adult-onset genetic diseases because it places an unfair constraint on a child’s right to an open future. It both removes the child’s ability to choose whether to be tested as an adult and has the potential to negatively alter the overall trajectory of their lives. While the current consensus amongst medical professionals is that such testing should be prohibited (Davis, _____), many concerned parents correctly point out that discouraging such testing creates a conflict of interests between the “beneficence model of patient care and the rights of parents to their own autonomy”
The inclusion of genetic testing into Electronic Health Records impacts the overall healthcare of patient’s because it informs the physicians and other medical professionals the selection of effective treatment or preventive action. A manager’s responsibilities are to implement policies to protect the confidentiality, privacy, and security of genetic tests results and information of patient’s. Policies contributing to potential discrimination acts are also advised because genetic/genomic testing reveals a patient’s physical characteristics.
Genetic testing has become a highly controversial issue among both the general population and the scientific community. It is a process that exposes a person’s entire genome sequence, allowing it to be read and evaluated to identify potential risks for genetic diseases or diseases that could be passed onto offspring (Holt Productions, 2012). With thousands of genetic tests already being used, and more being established, it seems logical to put this growing technology to use. Some agree that it is a person’s right to know and understand his or her genetic makeup. However, others argue that, despite the benefits of genetic testing, caution should be used to carefully inspect the risks associated with this new technology.
Prenatal testing and genetic testing developed hand in hand. Many genes, the basic unit of heredity, are now known through the human genome project (Pence, 2011, pp. 273-274). Genetic testing can identify the existence of genes that carry potentially life impacting and threatening conditions. However, prenatal genetic testing can determine much more than simply the abnormalities or negative factors. It can indicate sex, hair and eye color, temperament,
The Goal of the Human Genome Project is to obtain genetic mapping information and to determine the complete sequence of all human DNA by the year of 2005. The project started in 1990 and 180 million dollars are being spent on it annually. This adds up to a total of over 2 billion dollars for the 15 year budget. Of this 2 billion dollars budgeted, 5% is spent annually on the ethical, legal and social issues. This report focused on some of these issues.
The testing is not a bad idea as such but it should not be done to children. This regards to personal autonomy where it would be better if the testing is delayed until an individual is old enough to make his or her own decision about the test. A person’s genetic information should be private and counselling should be done to elucidate the basis for and consequences of the test in question. Individuals should be allowed to choose when and which
With so many advances in medical technology, ethical dilemmas often accompany the advances. Genetic testing continue to be one of the most heated ethical debate in today’s health care. In 1963, newborns began to be tested for phenylketonuria (PKU), an amino acid buildup in the blood that causes mental retardation. This is the earliest genetic testing documented in the health care of the United States. Today, more than 2,500 available genetic testing are available to the public where the lowest cost reported is a DNA home kit for one hundred dollars. In 2013, the famous actress, Angelina Jolie, undergone a preventive double mastectomy after the BRCA genetic tests that revealed she was at a high
In one side if the results are negative will provide great relief and peace of mind, while a positive result will facilitate the prognosis, early treatment and a positive effect on quality of life and life expectancy. Two important examples of the benefit of having more access to genetic information are the newborn screening and cancer screening. The first one allows the detection and early management of serious conditions such as phenylketonuria in newborns. The second one is of vital importance in the early detection of cancer as long as the evaluation and follow-up in those patients who have higher predisposition to suffer this disease. The regular screening of prostate, breast, and ovarian cancer, to mention some, have helped to identify individuals at risk based on their family history and to improve the management of the condition increasing their regular check-ups
In the 20th century, genetic testing was initiated to determine whether an individual had a genetic disorder or not. Newborns were tested for a condition known Phenylketonuria (PKU). PKU is a condition where by a buildup of an amino acid known as phenylalanine in a baby’s body leads to intellectual impairment and possible brain damage. This amino acid is built up when a baby lacks an enzyme that converts phenylalanine into another amino acid called tyrosine. The screening tool used is known as the Guthrie test whereby blood is collected from the heel of a new born and tested for the presence of PKU. If the PKU content is above 1-2mg/dl, then the baby has PKU. Early detection of this condition has helped to preserve the brain function of the child. Also, the child is
genetic testing, everything has changed. She notes that clinicians now have the ability to diagnose, treat, and monitor a patient’s illnesses or disease progression in an entirely different manner. This is a far cry from the old medical model of responding to a disease (or defect) only after it appears, and then prescribing the recommended medication or intervention. These genetic medical advances sound miraculous and promising, but the ability to test, screen and provide early intervention does not come without many major ethical dilemmas.
