Genetic testing is critical in determining cancer treatments and potential risk of family members for developing the disease. However, when an individual decides to review them, they may not know what to expect.

In a recent interview with CURE®, Dr. Ami P. Vaidya, co-head of the gynecological oncology division and vice chair of the Obstetrics and Gynecology department at Hackensack Meridian Health University Medical Center, outlined the process and encouraged people to undergo genetic testing if they were eligible- can.

The process will begin with a consultation, either with a genetic counselor or a member of the cancer care team. Family history will be collected, including the cancer history of family members and the age when they were diagnosed.

How Hereditary Genetic Testing Results Impact

Then, individuals are more likely to draw blood – although some tests allow for a buccal swab to be collected from inside the cheek. “So there are two ways to do tests, both of which I would say are minimally invasive,” Vaidya said.

The sample is then reviewed, where experts look for various genetic mutations that may be associated with an increased risk of cancer or help decide treatment options for someone who has already received a diagnosis.

“The test results are processed and run in different labs. Typically, the turnaround times we see are about two weeks, during which a very detailed report is generated,” Vaidya said. explaining that the next step is another consultation where the results are explained to the patient or family member.

In this complex process, patients and their loved ones may worry about the cost of genetic cancer tests – especially since those tests have come at a high price in recent years.

Genes And Cancer

“There are so many (insurance) plans, and every plan is different, but I can tell you that most plans – including Medicare and Medicaid plans – cover what we call Cascade genetic testing,” Vaidya said, explaining that Cascade testing looks for a certain genetic mutation in the direct family member (s) of a cancer patient known to have such a mutation.

“Tests running in the thousands of dollars are in the hundreds of dollars now (price range), so it’s really a big change in price,” Vaidya said. “Waterfall testing is one of the areas where we can make a big, positive impact. So (genetic testing companies) are very, very willing to work with individuals – especially those without insurance.”

Genes carry instructions for making proteins, which do great work in our cells. Certain genetic changes can cause cells to avoid normal growth controls and growth. For example, some genetic modification causes an increase in the production of a protein that makes cells grow. Others result in the production of a deformed and therefore dysfunctional form of a protein that normally repairs cell damage.

The Genetics Of Cancer

The genetic changes they promote can be inherited from our parents if the changes are present in germ cells, which are the body’s reproductive cells (eggs and sperm). Such changes, called germline changes, are found in all the cells of the offspring.

Caused by genetic changes can also be acquired throughout life, as a result of errors occurring during cell division or exposure to carcinogens that damage DNA, such as certain chemicals in tobacco smoke, and radiation, such as ultraviolet rays from the Sun. Genetic changes that occur after conception are called somatic (or acquired) changes.

There are many different types of DNA changes. Some changes affect only one unit of DNA, called the nucleotide. One nucleotide may be replaced by another, or it may be completely absent. Other changes involve larger stretches of DNA and may include rearrangements, deletions or duplication of long stretches of DNA.

Sometimes the changes are not in the actual DNA sequence. For example, adding or removing chemical markers, called epigenetic modifications, to DNA can influence whether the gene is “expressed”, i.e., if and how much messenger RNA is produced. (Messenger RNA, in turn, is translated to produce DNA-encoded proteins.)

In general, cells have more genetic modification than normal cells. But each person has a unique combination of genetic changes. Some of these changes may be results rather than causes. As it continues to grow, there will be further changes. Even within the same tumor, the cells can have different genetic changes.

Inherited genetic mutations play an important role in approximately 5 to 10 percent of all cancers. Researchers have linked mutations in specific genes to more than 50 hereditary syndromes, which are diseases that can motivate individuals to develop certain diseases.

Genetic testing for inherited syndromes can determine if someone in a family who shows signs of such a syndrome has one of these mutations. These tests can also show if family members without obvious disease inherited the same mutation as a family member with the associated mutation.

Many experts recommend considering genetic testing for risk when a person has a personal or family history that suggests an inherited risk condition, as long as the test results can be properly interpreted (i.e. is, they will clearly know if there is a particular genetic change (or not) and when the results provide information that will help guide a person’s future medical care.

A Step By Step Guide To Cancer Genetic Testing

Diseases not caused by inherited genetic mutations can sometimes “run in families”. For example, a shared environment or lifestyle, such as tobacco use, can cause similar feelings to have family members. However, certain specific patterns in a family – such as the types that form, other unconditions observed, and the ages when it is formed – may suggest the presence of an inherited syndrome.

Genetic testing for mutations that cause inherited syndromes is usually ordered by a person’s doctor or other health care provider. Genetic counseling can help people consider the risks, benefits and limitations of genetic testing in their particular situations.

A genetic counselor, physician, or other health care professional trained in genetics can help an individual or family understand their test results and explain the possible implications of the test results for other patients. family member.

People considering genetic testing should understand that their results may be known to other people or organizations with legitimate and legal access to their medical records, such as their insurance company or employer, if the employer provides the patient’s health insurance as a benefit. Legal protections are in place to prevent genetic discrimination, including the Genetic Information Non-Discrimination Act of 2008 and the Privacy Rule of the Health Information Portability and Accountability Act of 1996.

The page on genetic testing for inherited suceptibility syndromes has more information on what tests are available and who may want to consider them.

Lab tests called DNA sequencing tests can “read” DNA. By comparing the DNA sequence in cells with normal cells such as blood or saliva, scientists can identify genetic changes in cells that may be driving an individual’s growth. This information can help doctors determine which therapies may work best against a particular tumor. For more information, see Testing Biomarkers for Treatment.

Tumor DNA sequence may also reveal the presence of an inherited mutation. In fact, in some cases, genetic testing of tumors has shown that a patient may be associated with an inherited syndrome unknown to the family.

Like testing for specific mutations in inherited syndromes, clinical DNA sequencing has implications that patients need to consider. For example, they may inadvertently learn about having an inherited mutation that can cause other illnesses, either to them or to their family members. treatment in accordance with guidelines. see more

How To Get Genetic Testing For Cancer

ANN ARBOR, Michigan – Women with early -stage breast cancer who test positive for an inherited genetic variant do not always receive cancer treatment that follows current guidelines, according to a new study.

An inherited gene can increase the risk of developing secondary breast cancer, so techniques such as removing a woman’s breasts or ovaries are aimed at preventing future cancer. But women who have been diagnosed with breast cancer should also consider how best to treat the existing tumor.

“Cancer treatment options are increasingly complex for patients., MPH, senior author of a study led by the University of Michigan Rogel Cancer Center and
