Clinical Validation of Early Detection Blood Test for Universal Large-scale Breast Cancer Screening
What this study is about
Breast cancer is the most common cancer that spreads beyond the initial layer of tissue it developed in, and grows into surrounding healthy tissue in women worldwide. It is associated with significant illness and death. Identifying the disease in the early stage is important to achieving positive outcomes in response to diagnosis and treatment.
View original scientific description
Breast cancer is the most common cancer that spreads beyond the initial layer of tissue it developed in, and grows into surrounding healthy tissue in women worldwide. It is associated with significant illness and death. Identifying the disease in the early stage is important to achieving positive outcomes in response to diagnosis and treatment. The Syantra blood test has been developed over the past 10 years. This test involves examining blood samples to identify and analyze specific information. This information is run through a software program that then potentially identifies the presence of breast cancer in the blood sample. This test has the potential to increase early stage detection of breast cancer. The main goal of this study is to figure out how well the Syantra blood test identifies the presence of breast cancer in women 30-75 years of age. The study will also look at whether things like ethnicity, geography and certain individual characteristics (including breast density and elevated risk of breast cancer development) have an effect on how well the test works. This study will recruit women who are attending a visit at the site who are aged 30-75 who are undergoing testing for the presence of breast cancer as part of their regular screening or planned follow up imaging and/or biopsy. Participants who provide consent and meet eligibility criteria will complete a baseline questionnaire and have their blood drawn before any scheduled procedures. Relevant information will be collected from their medical record at the time of joining the study and will be reviewed and updated within 60 days and then again at 12 months following the baseline blood draw. Participants will not have to do anything after the initial visit where they may sign consent, complete the intake questionnaire and have their blood drawn.
Primary outcome measures
Sensitivity
Time frame: 3 years
Sensitivity (Se) if the test = TP/TP+FN), ratio of true positives to true positives and false negatives
Specificity
Time frame: 3 years
Specificity (Sp) of the test = TN/ (TN+FP), ratio of true negatives to the true negatives and false positives
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria

- Willing and able to give Written Informed Consent and provide a whole blood sample
Exclusion criteria
- Physical breast symptoms or concerns
- Current or suspected cancer diagnosis
- Prior BI-RADS 3 or higher imaging results in last 12 months
- Breast surgery within the previous 12 months (for any reason) or recent breast biopsy (including needle core biopsy) within the last 12 months
- Previous history of any cancer, except for non-melanoma skin cancer (basal cell carcinoma and squamous cell carcinoma)
- Previous history of invasive or non-invasive breast cancer
- Concomitant or other concurrent anti-cancer therapy
- Blood transfusions within the past 3 months
- Born biologically male B. Recall Inclusion Criteria
- Age ≥ 30 and ≤ 75
- Previous MRI (for women who qualify) and/or screening mammogram (and/or breast ultrasound) indicating follow-up imaging or biopsy recommended
- Presentation of factor(s) indicating elevated risk for breast cancer development o Factors may include germline genetic mutations known to increase risk of breast cancer, very dense (D) breast tissue, family history, and/or clinical risk assessment and scoring at elevated risk (20% or greater lifetime risk, or 3% or greater 10-year risk assessed at age 40, using the Tyrer-Cuzick model (v.7 or v.8) or BOADICEA v6.0 or 1.67% or greater 5-year breast cancer risk using the BCSC model.
- Willing and able to give Written Informed Consent and provide a whole blood sample Exclusion Criteria
- Physical breast symptoms or concerns
- Breast surgery within the previous 12 months (for any reason) or recent breast biopsy (including needle core biopsy) within the last 12 months
- Current diagnosis or history of any cancer, including DCIS, with the exception of non-melanoma skin cancer (basal cell carcinoma and squamous cell carcinoma)
- Blood transfusions within the past 3 months
- Born biologically male
- Recall (Secondary care) Symptomatic population: Women recommended for follow-up due to physical symptoms. This includes recommendation for diagnostic imaging and/or biopsy due to physical symptoms. Inclusion Criteria
- Age ≥ 30 and ≤ 75
- Planned diagnostic breast imaging (mammogram, breast MRI and/or breast ultrasound) and/or breast biopsy, as recall or follow-up from prior examination or to evaluate breast symptom.
- Willing and able to give Written Informed Consent and provide a whole blood sample. Exclusion Criteria
- Current known cancer diagnosis
- Breast surgery within the previous 12 months (for any reason) or recent breast biopsy (including needle core biopsy) within the last 12 months
- History of any cancer, with the exception of non-melanoma skin cancer (basal cell carcinoma and squamous cell carcinoma)
- Blood transfusions within the past 3 months
- Born biologically male
- Asymptomatic average, low or unknown risk population: Women undergoing routine screening for breast cancer. Women in the Screening population would have no physical symptoms and be consented near the time of a screening imaging session (within 3 months). Recruitment may also occur after a screening imaging session with a recommendation for follow-up imaging, or after diagnostic imaging with a recommendation for a biopsy as part of the recall population. Inclusion Criteria
- Age ≥ 30 and ≤ 75
- Screening mammogram and/or breast ultrasound, breast MRI within 3 months
- Willing and able to give Written Informed Consent and provide a whole blood sample Exclusion Criteria

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
