Understanding your genetic risk can be a life-changing step in preventing and managing cancer.
With advancements in precision medicine, Cancer Genetic Testing offers a clearer picture of how your DNA influences your chances of developing certain cancers.
Whether you have a strong family history or simply want to be proactive about your health, learning how genetic testing works—and how to access it through a trusted provider—can lead to better prevention, treatment, and peace of mind.
In this guide, we'll explore the purpose of genetic testing, how it’s performed, who should consider it, and how Premier Hematology premier cancer care & infusion center supports patients every step of the way.
What is Genetic Testing?
Genetic testing is a laboratory method that examines your DNA to identify mutations or alterations that may increase your risk of certain diseases, including cancer.
In the context of Cancer Genetic Testing, the goal is to find inherited mutations—those passed down from parent to child—that are linked to specific types of cancer.
This form of testing can help detect alterations in genes like BRCA1/BRCA2, TP53, MLH1, and others.
These genes, when functioning properly, help prevent cells from becoming cancerous. Mutations may disrupt these processes and allow cancer to develop more easily.
Unlike routine medical screenings, genetic testing does not diagnose cancer—it evaluates your risk of developing it over time.
This proactive approach can lead to early intervention and more effective management strategies.
Genetic Testing for Cancer
Cancer Genetic Testing focuses on identifying hereditary cancer syndromes—conditions where certain cancers run in families due to inherited gene mutations.
This type of testing is particularly relevant for individuals with a personal or family history of cancers like:
- Breast and ovarian cancer
- Colorectal cancer
- Prostate cancer
- Pancreatic cancer
- Melanoma
- Uterine and endometrial cancers
Genetic testing can help inform your healthcare provider about the best strategies for early detection, prevention, and treatment.
For example, individuals with a BRCA1 mutation may benefit from earlier breast cancer screening, while those with Lynch syndrome may need more frequent colonoscopies due to elevated colon cancer risk.
These insights are especially important if you're considering targeted therapies or enrolling in clinical trials that match treatments to your unique genetic profile.
Types of Genetic Testing for Cancer
There are several types of Cancer Genetic Testing, each designed to provide specific information:
Single-Gene Testing
This test focuses on one gene, usually when a specific mutation is already known in the family.
For instance, if a parent has a BRCA2 mutation, their children may be tested for that exact variant.
Multi-Gene Panel Testing
Panel testing examines multiple genes simultaneously.
This approach is helpful when a family's cancer history suggests more than one possible genetic cause.
It's a cost-effective and time-efficient option used in many modern screening protocols.
Whole Exome Sequencing
This method evaluates all protein-coding regions of the genome and can uncover rare or unexpected mutations.
While not typically used for routine cancer screening, it may be helpful in complex cases.
Germline vs. Somatic Testing
- Germline testing evaluates inherited mutations found in all cells of the body.
- Somatic testing focuses on acquired mutations found only in cancer cells, typically used to guide treatment after a cancer diagnosis.
Whether you’re considering genetic testing of colon cancer or evaluating breast cancer risk, the type of test you undergo depends on personal and family history, medical indications, and clinician recommendations.
Why Should I Test?
Many people wonder, "Do I really need genetic testing if I feel healthy?" The answer depends on your risk factors—but the benefits of Cancer Genetic Testing go far beyond peace of mind.
Here's why you should consider testing:
- Risk Identification: Discover if you carry inherited mutations that increase your cancer risk.
- Early Detection: Use your results to create a customized screening schedule that catches cancer earlier, when it’s most treatable.
- Preventive Action: Discuss risk-reducing strategies with your doctor, including lifestyle changes and, in some cases, preventive surgery.
- Family Awareness: A positive result can help family members assess their own risk and consider testing.
- Tailored Treatment: If you're already diagnosed with cancer, test results can guide therapy decisions based on specific genetic drivers.
Knowing your genetic status puts you in a position of power—able to make informed, proactive decisions about your future health.
How is Testing Done?
Cancer Genetic Testing is a relatively simple and non-invasive process.
Most tests require only a saliva sample or a blood draw.
Here's how it typically works:
Step 1: Pre-Test Consultation
You'll meet with a genetic counselor or trained clinician who will review your personal and family medical history. They’ll help you understand what the test can (and can't) tell you.
Step 2: Sample Collection
A blood or saliva sample is collected and sent to a specialized lab that analyzes your DNA.
Step 3: Laboratory Analysis
Genetic scientists look for specific mutations or changes in the genes linked to hereditary cancers.
Step 4: Result Interpretation
Results are shared during a follow-up appointment, where the genetic counselor explains whether you have any pathogenic mutations, benign variants, or "variants of unknown significance."
Step 5: Action Plan
If a mutation is found, your care team at a premier cancer care & infusion center like Premier Hematology will guide you through screening, monitoring, and preventive care options.
Turnaround time can vary, but most test results are available within 2–4 weeks.
Where Can I Get Tested?
When searching for genetic cancer screening near me, it's essential to choose a reputable provider that offers both testing and follow-up support.
You can get tested through:
- Academic medical centers with oncology departments
- Certified genetic counseling clinics
- Specialty practices like Premier Hematology that offer integrated Cancer Genetic Testing services
- Telehealth services, which are becoming increasingly common for pre- and post-test consultations
The right testing environment includes not just lab results, but also expert guidance and coordination of care.
At Premier Hematology, we deliver a full-service experience from testing to personalized treatment planning.
Who Should Be Tested?
Not everyone needs Cancer Genetic Testing, but certain individuals are at higher risk and should consider it. You should be tested if you have:
- A personal history of early-onset cancer (before age 50)
- Multiple relatives with the same or related types of cancer
- More than one cancer diagnosis
- Ashkenazi Jewish ancestry with breast or ovarian cancer history
- Known genetic mutations in the family (e.g., BRCA1, MLH1, MSH2)
If you’re unsure whether you qualify, schedule a risk assessment with a specialist or premier cancer care & infusion center.
A qualified provider will evaluate your medical history and determine if testing is right for you.
Genetic Testing Colon Cancer
Colorectal cancer is one of the most common cancers with a strong hereditary component.
Inherited syndromes like Lynch syndrome and familial adenomatous polyposis (FAP) significantly increase colorectal cancer risk.
That's why genetic testing colon cancer is critical for early diagnosis and intervention.
Key points:
- Lynch Syndrome: Caused by mutations in genes like MLH1, MSH2, and MSH6. It also raises the risk of endometrial, ovarian, stomach, and other cancers.
- Testing Recommendations: People with family history of colon cancer or polyps should consider genetic testing by age 40—or earlier in some cases.
- Prevention Options: Patients with Lynch syndrome may benefit from frequent colonoscopies, low-dose aspirin, and even preventive surgery in some cases.

FAQs
What is the main purpose of Cancer Genetic Testing?
The primary purpose of Cancer Genetic Testing is to identify inherited genetic mutations that increase a person’s risk of developing cancer. This proactive screening helps individuals understand their long-term cancer risk based on DNA changes passed down from parents. Knowing your genetic status allows you and your healthcare provider to take preventive steps, schedule earlier screenings, or consider personalized treatments tailored to your genetic profile.
Is Cancer Genetic Testing the same as a routine cancer screening?
No. Cancer Genetic Testing is different from screenings like mammograms or colonoscopies. While those tests look for existing signs of cancer, genetic testing identifies inherited mutations that may increase your future risk. For example, genetic testing colon cancer helps detect Lynch syndrome long before any cancer develops, enabling earlier interventions.
Who is a candidate for Cancer Genetic Testing?
You may be a candidate for Cancer Genetic Testing if you have:
- A personal or family history of cancer (especially under age 50)
- Multiple family members with the same or related cancers
- A known mutation in the family (like BRCA1/2 or MLH1)
- Certain ethnic backgrounds (such as Ashkenazi Jewish heritage)
If you’re unsure, consult with a premier cancer care & infusion center like Premier Hematology to assess your eligibility.
How accurate is Cancer Genetic Testing?
Modern Cancer Genetic Testing is highly accurate at detecting mutations in the genes being analyzed. However, not all mutations are fully understood. Some results may show “variants of uncertain significance” (VUS), which require further study or family testing. Genetic counselors at Premier Hematology help interpret your results with clarity and context.
Can Cancer Genetic Testing help if I already have cancer?
Yes. If you've been diagnosed with cancer, Cancer Genetic Testing can guide treatment. Some mutations may indicate that you'll respond better to certain targeted therapies or immunotherapies. For example, a BRCA mutation could make you eligible for PARP inhibitors. This is why genetic testing colon cancer or breast cancer is sometimes recommended during or after diagnosis.
Is my privacy protected when I get genetic testing?
Yes. Your genetic information is protected by federal privacy laws, including HIPAA and the Genetic Information Nondiscrimination Act (GINA). At Premier Hematology, all Cancer Genetic Testing is conducted in a secure, confidential manner. Your results are shared only with you and your authorized medical team.
How often should I repeat genetic testing?
Typically, Cancer Genetic Testing only needs to be done once. However, in rare cases, you may need retesting if new mutations are discovered in the future, or if your personal or family history changes significantly. Multi-gene panels and updated tests may also become available. Your care team at Premier Hematology will guide you if follow-up testing becomes necessary.
