What's this test for?

This test is ideal if you're navigating a cancer diagnosis and need more information about the specific genetic changes driving your tumor. It looks for KRAS gene mutations, which are common in cancers like lung, pancreatic, and colorectal cancer. Knowing your KRAS status can help clarify treatment options, since some therapies work differently depending on whether this mutation is present.

What's included in this test?

This test analyzes tumor tissue for mutations in the KRAS gene, focusing on the specific hotspot locations where changes most commonly occur. These mutation sites matter because they affect how cancer cells grow and how they respond to certain targeted drugs. Identifying the exact mutation helps determine whether a cancer is likely to respond to particular treatment approaches.

What happens after I get my results?

Your results will be available in your account, with an explanation of what a positive or negative KRAS finding means. If a mutation is detected, the report outlines what that finding typically means for treatment approach and prognosis, and next steps might include discussing targeted therapy options relevant to your mutation type. You can download a standard lab report directly from your account at any time. Since this is typically a one-time diagnostic test tied to a specific tumor sample, ongoing trend tracking isn't usually needed, but the platform supports it if repeat testing is ever recommended.

How can I naturally support my body during cancer treatment?

While no lifestyle change can replace targeted cancer treatment, some habits can support your body through the process. Eating a nutrient-dense diet with adequate protein helps maintain strength during treatment, and staying hydrated supports overall organ function. Gentle physical activity, when tolerated, and stress-reduction practices like meditation can help with fatigue and mood. Always pace these changes around how you're feeling and any specific guidance you've received about your treatment plan.

When will I get my results?

Results for this KRAS mutation analysis are typically ready within about 7 days of your sample being processed at the lab. This turnaround allows time for the detailed genetic analysis required to detect specific mutation sites. You'll be notified as soon as your results are posted to your account.

Who should consider this test?

This test is most relevant for people who have already been diagnosed with a cancer type known to have KRAS mutations, such as lung, pancreatic, or colorectal cancer. It's also useful for those exploring eligibility for targeted therapy clinical trials, since many newer treatments are designed specifically for KRAS-mutated tumors. This isn't a general cancer screening test — it's a molecular analysis used after a diagnosis to guide treatment decisions.

What does a positive KRAS mutation result mean?

A positive result means your tumor cells carry a change in the KRAS gene that affects how they grow and divide. This finding is often linked to a more aggressive disease course and can mean that certain targeted therapies, like some EGFR-directed drugs, are less likely to work well. On the positive side, specific KRAS mutations like G12C now have dedicated targeted treatments being studied and used, so this result can help match you to newer options.

What does a negative KRAS mutation result mean?

A negative result means the specific KRAS mutations tested for were not found in your tumor sample. This can be helpful because it may keep certain targeted therapy options open that work better in KRAS-unmutated tumors. It doesn't rule out other genetic changes, so additional tumor marker testing might still be useful.

What causes KRAS mutations to develop?

KRAS mutations are acquired changes that happen within tumor cells themselves, not something inherited from your parents or caused by daily lifestyle habits. They occur as part of the random genetic errors that build up as cells divide, sometimes influenced by long-term exposures like tobacco smoke in lung cancer. These mutations then give the affected cells a growth advantage, contributing to tumor development.

What should I do if my results show a KRAS mutation?

If your results are positive, it's a good idea to look into treatment options and clinical trials specifically designed for your mutation subtype, such as G12C-targeted drugs. Keep a copy of your lab report handy, since this information is often needed when discussing treatment planning. Consider asking about additional tumor profiling, since cancers can carry multiple relevant mutations beyond KRAS. Reach out for medical care promptly if you experience any new or worsening symptoms.
