Testing for a strong genetic mutation linked to an increased risk of breast cancer has increased significantly in women over 40 who have been diagnosed with the disease, according to a new study.
Overall, within a year of diagnosis, 87 percent of women who had breast cancer screenings were tested for breast implants.

Organic matter. Mutations in any of these genes increase a woman’s risk of having breasts later in life, her risk of developing breasts at an early age, and her risk of developing ovarian cancer.
Hereditary Breast Cancer Risk And Genetic Testing
The number of women tested increased steadily over the seven-year period of the study from about 77 percent of those diagnosed in 2006 to almost all women in 2013.
A genetic mutation can not only affect the patient’s treatment decision, but it can also affect the patient’s family. That’s why doctors often encourage girls who have been diagnosed with breast cancer to get tested
Mutation tests are low in the minority of women diagnosed with breast cancer, about 20 to 25 percent, Dr. Rosenberg and colleagues observed. However, visibility

The current study included nearly 900 women diagnosed with breast cancer aged 40 years or younger between August 2006 and December 2013 and treated at 11 academic or community centers.
In the first two years of the study, 70-80 percent of participants were tested within a year of diagnosis. This percentage increased significantly in the following years, when all but a few of the women diagnosed in 2012 and 2013 received a test (96.6 percent and 95.3 percent, respectively). About 80 percent said they received their test results within 3 months of diagnosis.
“More awareness may make women more likely to present genetic risks to their doctors, which may lead to more testing,” Dr. Rosenberg said in a press release.
About 30 percent of women who were tested and had positive or negative results (some women had inconclusive results) reported that it affected their care. In this group, 86 percent of those who received a
Non Brca Gene Mutations That Raise Breast Cancer Risk
In the mutation, both the affected breast and the healthy breast are surgically removed (secondary mastectomy), as opposed to the affected breast; 53% had their ovaries and fallopian tubes removed (salpingo-oophorectomy).
More than half of the women in this group who did not have a replacement also had a second mastectomy, although only a few had a salpingo-oophorectomy.
The mutation test, about half said it was because they didn’t think they could get the mutation or because their doctor thought it was unlikely they would get the mutation.
A trial among young women receiving treatment in the community. For example, nearly all study participants had health insurance, and all were treated at centers with comprehensive counseling and testing services, they wrote.

The test will probably be too low in that case,” says Lyndsay Harris, MD, of the NCI’s Division of Clinical Research. It may also be less familiar with the recommendations.
, Jeffrey Weitzel, MD, of the Hope Institute in Duarte, Calif., and colleagues noted that they were “guilty” to see more girls diagnosed with breast cancer undergoing genetic risk counseling. But the research was not effective, they continued.
“Worryingly, 48 percent of those who were not tested reported that they and/or their doctor did not agree.
Those with mutations,” she said. “So it raises the question of whether there is bias in informing women.”

Mutation with a second mastectomy “may suggest that there is a need for better communication about the low risk of breast cancer in non-carrier women… and that a second mastectomy is not associated with a better survival. “
Women who are diagnosed with breast cancer and are expanding the use of other genetic tests, Dr. Weitzel and colleagues wrote. The next series “brings a new era” of testing for genetic changes.
Some of the women in this study may have had genetic changes detected by these multigene tests, such as mutations
But “the majority of moderate and low-level diseases currently in multigene panels do not reach a level of risk that would justify” the method, they warned. Genetics is the study of genes. Genetic testing can be very helpful in identifying increased risk for certain types of cancer in patients and their families. Our genes instruct our cells for normal cell growth and development. A genetic error is called a mutation. Cancer cells develop when cells change and cannot function normally. According to DNSc’s Suzanne M. Mahon, “One of the most important things you can do to reduce your chances of developing cancer is to know your family history and seek risk assessment and genetic counseling if there are multiple cancers in your family.” your family.”
Brca Testing In Young Cancer Patients
Somatic or “acquired” mutations are the most common cause of cancer. A mutation occurs during a person’s lifetime, usually as a result of something or something called a carcinogen. A carcinogen is something that causes cancer, such as tobacco and other toxic chemicals.
Mutations in the family line, or “inheritance”, are passed directly from parent to child. When it comes to cancer, certain inherited traits or genetics can make a person more susceptible to cancer. About 10 percent of all cancers are hereditary. Each person has 2 copies of a specific gene, one from each parent. If a person inherits a gene mutation from either parent, they still have one normal copy. This does not mean that a person will develop cancer, but the possibility is higher because of the mutation.
The potential benefits, limitations, and risks of genetic testing, as well as the individual’s psychological readiness, should be discussed with a healthcare professional (HCP) before genetic testing is offered. In the past, genetic testing focused on one or two genes. However, the introduction of multigene testing for hereditary cancer types has changed the screening of at-risk patients and their families. These tests simultaneously analyze genes associated with a specific disease. Multigene testing is more cost effective and increases the likelihood that genetic variants will be found. It is a good idea to check coverage with other insurance companies before getting genetic testing. Many plans, such as Medicare, have specific testing requirements.
Health care providers ask patients to fill out a questionnaire with information about family medical history, which includes first and second relatives on both the mother’s and father’s side. It must be as detailed and accurate as possible. HCP uses a chart called a pedigree to chart family history. A blood or urine sample is required for testing, and results are available after 2-3 weeks. This information will help determine if further tests are needed.

Biologists recommend that a person keep in touch periodically to see if there are any additional tests. Genetic risk assessment is a dynamic process and may change if other relatives are diagnosed with cancer.
A positive diagnosis means that a mutation has been identified that increases the risk of developing cancer. A positive mutation cannot predict when or if the disease will occur.
Bad truth means that the person did not inherit the replacement. A person has the same risk of developing cancer as normal.
A variant of unknown origin (VUS) means that the test has detected a mutation, but it is not yet known whether it is a harmful mutation.
Do You Have A Family History Of Breast Cancer? Genetic Testing
According to the NCCN, the goal of genetic counseling is to enable an individual to make an informed decision about genetic testing, cancer screening, and cancer prevention. Factors that increase the risk of developing breast cancer include family history, age, race/ethnicity, breast size, and lifestyle factors such as alcohol consumption, obesity, and long-term use of hormones.
Risk-reducing behaviors focus on maintaining a healthy lifestyle, such as exercising, maintaining a healthy weight, and quitting smoking. Those with positive results should talk to their HCP about risk reduction in particular. Those who test positive may be eligible for risk-reducing surgery, either mastectomies (removal of both breasts) or hysterectomy with salpingo-oophorectomy (removal of uterus and ovaries). Although this helps reduce the risk, it does not eliminate the risk of cancer. Some people may take medications prescribed by an oncologist to reduce the risk of certain cancers.
An authorized or qualified genetic counselor must provide advice after the test and include explaining the results and discussing the meaning of the results, as well as the choice of medical treatment and care. If there are differences, talk to the other family members involved
