Home breast cancer testing is a convenient and easy way to screen for the disease. Learn about the different types of home tests available and how to choose the right one for you.

Testing For Breast Cancer At Home

Breast cancer is the most prevalent cancer worldwide. Researchers predict that it will account for 1 million deaths by 2040 and 3 million new cancer cases.

Learn about the different home testing options for breast cancer screening. These tests can help you detect breast cancer early, when it's most treatable.

Introduction

While the exact cause of breast cancer remains unclear, hormonal, environmental<a href="#accordion">[1]</a>, and lifestyle factors are known to increase the risk in people. Approximately 5 to 10% of breast cancers are a result of inherited genetic mutations<a href="#accordion">[2]</a>. Mutations in the breast cancer 1 and 2 genes (BRCA1 and BRCA2) are most commonly implicated in hereditary breast cancers, accounting for 3% of cases and 10% of ovarian cancer<a href="#accordion">[3]</a>.

Although not all individuals with these mutations go on to develop <a href="https://merisehat.pk/disease/types-of-breast-cancer">different type of&nbsp; breast cancer,</a> those with a strong family history of breast or ovarian cancer are often recommended for genetic testing. Genetic testing is traditionally done in a medical setting, but recent advances have brought this technology to people&rsquo;s doorstep. 
&nbsp;

Understanding At-Home BRCA Gene Test

At-home breast cancer genetic tests provide a convenient and accessible option for women to understand their genetic predisposition to breast cancer. These tests usually involve collecting a saliva sample and sending it to a certified laboratory for analysis. Results are then shared securely with the individual, eliminating the need for a clinic visit and reducing the burden on healthcare facilities.

In 2018, the US Food and Drug Administration (FDA) authorized the first direct-to-consumer test for BRCA1/BRCA2 gene mutation<a href="#accordion">[4]</a>. The test analyzes DNA from a self-collected saliva sample and can indicate if a person has an increased risk of breast, ovarian, or prostate cancer. It can take around 3-4 weeks for the results to return. However, it only detects three out of over 1,000 known BRCA mutations, so a negative result doesn&#39;t rule out other cancer-related gene mutations. 
&nbsp;

As per FDA&rsquo;s statement, the test can not be used to make treatment decisions, such as anti-hormone therapies or preventive surgeries. Confirmatory testing and genetic counseling are necessary for such decisions. The test also doesn&#39;t provide overall cancer risk information, and most cancer cases are not caused by hereditary gene mutations alone. Lifestyle factors like smoking, obesity, and hormone use also contribute to cancer risk.

Several other at-home genetic tests are now also available to detect the risk for breast cancer in individuals. These include ColorGenomic&rsquo;s cancer test, FuturaGenetics&rsquo; DNA test, and the Ultimate Genome Sequencing Breast Cancer Package by Sequencing. 
&nbsp;

If you get a positive result on an at-home genetic test, it&#39;s essential to talk to your healthcare provider and confirm the results. They might suggest more specific genetic tests that consider your family history and risk factors. In some cases, additional diagnostic tests like imaging and biopsy may be recommended. 
&nbsp;

For certain breast cancer gene mutations, women might opt for preventive surgeries like mastectomy (breast removal), oophorectomy (ovary removal), or hysterectomy (uterus removal) due to the increased risk of ovarian or uterine cancer.

Decisions about further testing and treatment are complex and life-changing, so it&#39;s crucial to seek advice from experienced medical professionals who understand cancer outcomes and treatment options<a href="#accordion">[5]</a>. 
&nbsp;

The exact reasons behind breast cancer are not fully understood. Most cases are not linked to genetic mutations or family history, and many people who get breast cancer have no previous family history of the disease.

It&#39;s crucial not to assume that a normal test result guarantees you won&#39;t develop breast cancer. At-home genetic tests can only detect a small number of breast cancer genes. Even if your genetic test is normal, regular breast cancer screening is still essential for you. Early detection remains vital in catching any potential issues<a href="#accordion">[5]</a>. 
&nbsp;

At-home breast cancer genetic tests have both pros and cons. On the positive side, these kits offer convenience and are usually more affordable, costing around $200 to $300, compared to similar tests at healthcare clinics. They can be beneficial for individuals with limited access to genetic testing through their healthcare provider.

However, there are some drawbacks to consider. Many at-home kits can only detect a few of the most common BRCA mutations, missing out on the full range of over 1,000 possible mutations. This can lead to potential false-negative results, where a person might have a gene mutation but the test doesn&#39;t detect it.

Moreover, at-home tests lack direct genetic counseling. Without proper counseling, individuals may misinterpret results or miss crucial information about their risk.

In conclusion, while at-home breast cancer genetic tests offer convenience and affordability, they have limitations in detecting mutations and lack professional guidance. It&#39;s essential to use these tests as an initial step, but always consult with a doctor or a genetic counselor for accurate and comprehensive information about your breast cancer risk. 
&nbsp;

When it comes to genetic cancer testing, medical-grade tests are the way to go. These tests are ordered by doctors or genetic specialists and use noninvasive methods like blood or saliva samples.

Medical-grade testing is designed to answer important medical questions, such as whether you carry a mutation in a hereditary cancer gene. On the other hand, at-home testing kits are more for entertainment purposes and are not meant to provide medical answers.

The key differences lie in the thoroughness and accuracy of the tests. Medical-grade testing, like for BRCA gene mutations, analyzes thousands of gene variant options, while at-home kits usually consider only a few. Studies have shown that some direct-to-consumer test results include false positives, leading to misleading health risk assessments.

Another factor to consider is the impact of ethnicity on test accuracy. Medical-grade testing is more reliable across different ethnicities compared to at-home tests, which may miss certain gene mutations, especially in individuals of Asian or African American descent.

Medical-grade testing uses advanced laboratory techniques and validation methods, ensuring more accurate and reliable results. So, if you want accurate and meaningful information about your genetic cancer risk, it&#39;s best to rely on medical-grade genetic testing ordered by a professional. 
&nbsp;

Conclusion

At-home breast cancer genetic tests provide a simple and accessible means of understanding genetic predisposition, helping individuals take proactive steps in managing their breast cancer risk. As technology and research continue to evolve, these tests will likely play an increasingly significant role in early detection and prevention, ultimately contributing to a future where breast cancer mortality rates are significantly reduced. However, it is vital to remember that these tests are just one piece of the puzzle, and regular screenings, healthy lifestyle choices, and open communication with healthcare providers remain essential in the fight against breast cancer.
