Chelsea Green Pharmacy
Early detection plays a vital role in effective breast cancer management, not only during initial diagnosis but also after treatment has ended. Many patients who have completed their therapy often ask whether a blood test can help detect recurrence early. At Chelsea Green Pharmacy, we believe understanding your ongoing health is key to peace of mind, and regular monitoring can form an important part of recovery. Below, one of our clinicians answers the most common questions about the breast cancer recurrence blood test, including what it measures and when it is recommended.
Q: Can a blood test really detect breast cancer recurrence?
A blood test can provide important information that helps doctors monitor for signs of recurrence. While it cannot diagnose breast cancer on its own, it can detect specific proteins or tumour markers in the blood that may increase if cancer cells return or grow elsewhere in the body. These tests are typically used alongside imaging scans, physical examinations, and clinical assessments to build a complete picture of your health.
The main advantage of a breast cancer recurrence blood test is that it can pick up changes before symptoms appear. However, results must always be interpreted by a qualified clinician, as other conditions or factors can also affect marker levels.
Q: What markers do these blood tests measure?
The most common blood markers used to monitor breast cancer recurrence are CA 15-3 and CA 27.29. These proteins are sometimes released by breast cancer cells into the bloodstream, and rising levels can signal that the disease may have returned or progressed.
Some clinics also use tests that look for circulating tumour DNA (ctDNA), which detects tiny fragments of genetic material shed by cancer cells. This newer technology is still being researched but is showing promise for identifying recurrence at an earlier stage than traditional tests.
It is important to understand that these markers are not always elevated in everyone who experiences recurrence. For this reason, your doctor or pharmacist may recommend blood tests as part of a broader follow-up plan rather than as a single diagnostic tool.
Q: When are blood tests for recurrence usually recommended?
Blood tests are often used during regular follow-up appointments after treatment for breast cancer has finished. The frequency of testing depends on individual risk factors such as the type and stage of cancer, your treatment history, and your overall health.
In some cases, your specialist may order a breast cancer recurrence blood test if you develop new or unexplained symptoms, such as persistent fatigue, bone pain, or changes in weight. For many people, these tests are part of ongoing care rather than emergency assessments.
If you are concerned about recurrence or want to take a proactive approach to monitoring your health, you can book blood testing in London through our pharmacy. We work with trusted laboratories to provide reliable, confidential results and clear explanations of what they mean for you.
Q: Are blood tests a replacement for scans or check-ups?
No, blood tests do not replace other monitoring methods such as mammograms, MRIs, or ultrasounds. Instead, they complement them. Imaging provides a visual look at tissues, while blood tests detect biological changes that might not yet be visible. Together, they give a fuller picture of your recovery and ongoing health.
At Chelsea Green Pharmacy, we often recommend combining regular check-ups, imaging, and laboratory testing for the most effective follow-up plan. This approach ensures that potential changes are caught early and investigated quickly if needed.
Q: How accurate are these blood tests?
Accuracy depends on several factors, including the type of test and individual biology. Tumour marker tests like CA 15-3 and CA 27.29 are useful for monitoring trends over time rather than as a one-off measurement. A single elevated result does not necessarily mean cancer has returned, but a consistent rise across multiple tests may prompt further investigation.
For patients seeking reassurance, tracking these results over time can provide valuable peace of mind. It allows clinicians to identify patterns early and take appropriate steps if anything unusual arises.
Q: What happens if my test results are abnormal?
If your blood test shows higher-than-expected levels of tumour markers, your clinician will usually recommend further tests, such as imaging or additional blood work. These follow-up checks help determine whether the change is due to recurrence, treatment effects, or another condition.
It is natural to feel anxious when results are unclear, but it is important to remember that elevated markers can occur for many reasons. The key is to have ongoing professional guidance and regular follow-up to interpret your results in the right context.
Q: Can I arrange a breast cancer recurrence blood test privately?
Yes, private testing is available for patients who want more control over their monitoring schedule. At Chelsea Green Pharmacy, we make it simple to book blood testing in London for ongoing health checks, including cancer recurrence markers. Our clinicians explain which tests are appropriate, how often to repeat them, and what to expect from your results.
Private blood testing can be particularly helpful for those seeking additional reassurance between NHS follow-up appointments or who prefer a more flexible schedule. Results are shared confidentially and can be discussed directly with our pharmacists or your healthcare provider.
Q: What should I remember about breast cancer blood tests?
Blood tests are a useful tool in post-treatment care but work best as part of a broader monitoring plan. They provide insight into biological changes that might indicate recurrence, offering an extra layer of protection and reassurance.
