Learn about hereditary cancer
Knowledge of an increased genetic risk enables you to work with your healthcare provider to create a personalized plan designed to prevent or detect cancer at an earlier and more treatable stage.
10-15% of most cancers are due to inherited genetic mutations.1, 2, 4, 13
Hereditary cancer is caused by an inherited genetic mutation. It is typical to see a recurring pattern of cancer across two to three generations—like multiple individuals diagnosed with the same type of cancer(s) and individuals diagnosed with cancer much younger than average.
Familial cancer refers to cancer that appears to occur more frequently in families than is expected from chance alone. While no specific mutation has been linked to these cancers, familial cancer may have a hereditary component that has not yet been identified.
Sporadic cancer refers to cancer that occurs due to spontaneous mutations that accumulate over a person’s life. Sporadic cancer cannot be explained by a single cause. There are several factors, such as aging, lifestyle, or environmental exposure, that may contribute to the development of sporadic cancer.
A mutation can greatly increase your risk for developing cancer.
Mutations in the genes covered by Color’s Hereditary Cancer Test are not common, but when present they significantly increase the chances of cancer.
For example, a BRCA1 mutation can increase a woman’s chance of breast cancer up to 81% by age 80.5 An APC mutation can increase a man or woman’s chances of colorectal cancer up to 70-100% by age 80 without surgical intervention.6, 7
Your provider may adjust your screening plan if you have a mutation.
Knowing that you have a mutation that increases your risk of developing cancer allows you and your healthcare provider to create a personalized screening plan, which increases the chance of early detection.
Detecting cancer early improves the odds of survival.
The 5-year survival rates for the cancers covered by Color’s Hereditary Cancer Test increase dramatically when they are caught at an earlier and more treatable stage.8
Knowing your risk can help you take action
You can work with your healthcare provider to create a personalized screening and prevention plan, designed to help reduce your risk of developing cancer. This might include:
Earlier and more frequent screenings
For example, if you have an increased risk for breast cancer, your healthcare provider might recommend mammograms at an earlier age.
Your healthcare provider may suggest preventive measures, such as certain medications that can reduce your cancer risk.
Proactive care for your family
As hereditary health disorders run in families, your results can help your loved ones understand their hereditary cancer risk.
How mutations impact women
A mutation can greatly increase a woman’s risk for developing hereditary cancer.
For example, a BRCA1 mutation can increase the chances of breast cancer up to 81% and ovarian cancer up to 54% by age 80.5
Mutations in the BRCA1 and BRCA2 genes are rare—found in approximately 1 in 300 individuals in the general population and in 2% of Ashkenazi Jewish individuals9 —but they significantly increase the chances of cancer. Mutations in other genes are more common, but have less of an effect on the risk of developing hereditary cancer.
How mutations impact men
A mutation can greatly increase a man’s risk for developing hereditary cancer.
For example, an APC mutation can increase the chances of colorectal cancer up to 70-100% by age 80 if untreated.6, 7
Mutations in the APC gene are rare—accounting for less than 1% of all colorectal cancers—but they significantly increase the chances of cancer. Mutations in other genes are more common, but have less of an effect on the risk of developing hereditary cancer.
A test you can count on. Based in evidence.
Unlike recreational genetic tests, we focus on thorough sequencing of genes to give you meaningful insights. We provide an affordable clinical-grade test that historically has cost thousands of dollars.
Thorough gene analysis
Just looking at snippets with recreational tests means you miss information – we take a more complete look.
Genes recognized by the CDC
We include all 10 genes recognized by the CDC as important for public health.10

This means no mutations associated with hereditary cancer were identified. It’s important to share your results with your provider to create a personalized healthcare plan.

It is common to see a genetic change that requires further research to determine if it is associated with an increased risk for developing a hereditary cancer. To date, most of the variants of uncertain significance that are further classified have been found to be harmless, though this process can sometimes take years.11
Knowing that you have a mutation that increases your risk of developing cancer allows you and your healthcare provider to create a personalized screening plan, which increases the chance of early detection. This is important because detecting cancer at its earliest stage improves the likelihood of a favorable outcome.8
A positive result, or finding a mutation, is not a cancer diagnosis, and does not mean that you will develop cancer. For example, most women have a 10% chance of getting breast cancer by the time they are 80, while a woman with a mutation in the BRCA1 gene can have up to an 81% chance.14 , Most men have a 2% chance of getting colorectal cancer by the time they are 70, while a man with a mutation in the MLH1 gene can have up to a 41% chance.15 ,16 The level of increased cancer risk differs from gene to gene.
