Can a workout fight breast cancer cells? new study investigates
NCT ID NCT07439458
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how a single session of aerobic exercise—either moderate or high intensity—affects breast cancer cells in the lab. Researchers will take blood from breast cancer survivors before and after exercise, then see if that blood slows the growth of breast cancer cells. They will also measure proteins released during exercise that might fight cancer. The goal is to understand which type of exercise might be best for cancer survivors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- aerobic exercise (high or moderate intensity)
- What this could lead to
- If successful, this could help identify the best exercise type and intensity to potentially slow breast cancer cell growth in survivors.
- What could go wrong
- This is a small, early-stage study (40 people) looking at lab effects, not patient outcomes. Results may not translate to real-world cancer control or apply to all breast cancer types.

Inclusion Criteria (intervention group): * Reproductive age (premenopausal); * Diagnosis of Stage II-III Triple-Negative Breast Cancer (TNBC) (negative for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2)); * Timeframe of 3 to 9 months after completion of surgery, adjuvant chemotherapy, radiation therapy, and/or immunotherapy; * Physician-certified (cardiologist) physical fitness for exercise testing, supported by echocardiography (ECHO). Inclusion Criteria (control group): * Reproductive age (premenopausal); * No current or prior diagnosis of any type of cancer; * Matched by age, body constitution, and physical fitness to the breast cancer participant group. Exclusion Criteria: * Pregnancy; * Autoimmune diseases (e.g., thyroiditis, inflammatory bowel disease, atopic dermatitis, etc.); * Endocrine disorders (e.g., metabolic syndrome, diabetes); * Cardiovascular diseases; * Diagnosis of any other type of oncological disease; * Any condition for which physical activity is contraindicated (e.g., asthma, COPD, spinal disc herniation, severe iron deficiency anemia).
