The availability of gene tests now allows everyone to glean into their genetic makeup to learn all sorts of things, from the elements shaping one’s personality and behavior via a personality DNA test in Singapore to identifying defective genes that could lead to developing certain diseases.
Misconceptions about genetic testing may confuse those unfamiliar with it. It is crucial for anyone considering this type of test to have all the right information before making a final decision. Below are some of the common gene testing myths and the truth behind them.
1. People with inherited cancer risk are guaranteed to develop the disease
There is a misconception that you are guaranteed to develop cancer if you have hereditary cancer syndrome. When an individual has the syndrome, it only means they will more likely get cancer but not for certain. Because of this increased risk, these individuals will need to make sure they undergo regular screenings.
2. Most cancer is attributed to an inherited risk
A genetic factor in your family does not cause most cancer cases. In fact, only around 5-10% of cancers have this kind of cause. For families with an inherited disease such as ovarian or breast cancer and uterine or colon cancers, a pattern can usually be noticed at much younger ages than sporadic cases would produce.
Other factors that may increase the risk of developing cancer are rare cancers like pheochromocytomas or medullary thyroid cancer, which have a higher portion because they’re passed down. In families with genetic disorders such as inherited cancers, genetic counselors can recommend screenings and prevention strategies that will help decrease the chances of getting them earlier in life. Knowing your family’s history is crucial if you want to be proactive about your risk for cancer.
3. Genetic testing for cancer risk is solely for women
It is equally vital for both men and women with a family history of cancer to undergo predictive genetic testing or be evaluated by a genetics professional. Everyone has genes that are supposed to protect them from cancer, and everyone can be born with gene mutations that increase their risk of developing the condition.
For instance, a BRCA gene mutation in someone’s family could lead to female relatives developing ovarian or breast cancer. In contrast, male relatives could have an increased risk of developing their own cancers, primarily prostate cancer, pancreatic cancer, or male breast cancer. Thus, it is recommended for men with a family history of female relatives developing breast cancer to get evaluated themselves.
4. Gene tests are expensive
Many people still assume that genetic testing will set them back thousands of dollars. While that may have been true years ago, the rise of competition and increase in insurance coverage has inevitably brought the price down to the point that it is now more affordable. Furthermore, genetic conditions are very stable. As a result, your DNA is unlikely to change throughout your lifetime. This makes it unnecessary for you to do another genetic test again after getting tested once.
Conclusion
Due to the complexity surrounding genetic testing and what it offers, it is only natural that mistruths would arise around the topic. If these myths are left unchecked, those interested in taking the test could be misguided, affecting their decision-making. Hopefully, with the contents above and proactive research, individuals can make a more informed decision.
