What is Genetic Testing for Cancer Risk?

Genetic testing for cancer risk looks at your DNA to find changes, called mutations, that could raise your chances of getting certain cancers. These tests do not find cancer itself. They only show if you have inherited a gene mutation that increases your risk.

Genes control how your cells grow and divide. If certain genes change, cells can start to grow in an abnormal way and form cancer. Most cancers are not inherited, but about 5 to 10 percent are caused by genetic mutations passed down from parents.

Genetic testing usually uses a blood or saliva sample. If a mutation is found, it means your risk is higher, but it does not mean you will definitely get cancer. A genetic counselor can help you understand what the results mean for you and your family.

What cancers are linked to Hereditary Gene Mutations?

Inherited gene mutations can increase the risk of several cancers, including:

• Breast cancer
• Ovarian cancer
• Colon cancer
• Prostate cancer
• Pancreatic cancer
• Kidney cancer
• Stomach cancer
• Thyroid cancer
• Uterine (endometrial) cancer

Researchers have identified 400+ genes linked to hereditary cancer risk. These genes fall into three main groups:

• Tumor suppressor genes, such as BRCA and TP53, usually stop cancer from growing.
• Proto-oncogenes help cells grow, but if they change, they can cause cells to grow out of control.
• DNA repair genes fix damage in your DNA. If these genes have mutations, they cannot repair the damage.

Who Should Consider Genetic Testing?

Your doctor might suggest genetic testing if you or your family show signs of inherited cancer risk.

You may need testing if you:

• Had cancer at a young age
• Have more than one type of cancer
• Have cancer in both organs (e.g., both breasts)
• Have rare cancers for your age or sex
• Have symptoms of inherited cancer syndromes

You may also need testing if your family history includes:

• Multiple relatives with the same cancer
• Cancer at a young age in relatives
• Known genetic mutations in the family

A healthcare provider or genetic counselor can help you decide if genetic testing is right for you.

How Does the Test Work?

Types of genetic tests include:

• Single mutation test – looks for a known mutation
• Single gene test – examines one entire gene
• Panel test – checks many genes at once

Today’s panel tests can find common inherited mutations with just one blood sample.

What to Expect Before the Test?

Before the test, you will meet with a genetic counselor who will explain:

• Whether testing is needed
• Which test is best for you
• Benefits and limitations
• Cost and insurance coverage
• Impact on you and your family

During and After the Test

• A blood or saliva sample is collected
• Results usually take 2–3 weeks
• Your privacy is protected by medical laws.

At-home tests are available, but they may not be as accurate or complete. Getting tested at a hospital is more reliable.

What are the test Results?

There are three possible results:

• Positive: A mutation is found; cancer risk is higher
• Negative: No inherited mutation found
• Variant of Uncertain Significance (VUS): A mutation is found, but its risk is unknown

A genetic counselor will explain what your results mean and help you with the next steps.

What are the benefits of Genetic Testing?

Genetic testing can help you in several ways:

• Reduce fear of the unknown
• Detect cancer early
• Plan preventive care
• Guide family planning
• Inform family members about their risk
