CyPath® Lung improves diagnostic clarity in patients with multiple lung nodules

In this case study, CyPath® Lung “Unlikely Malignancy” result supported physician’s decision to wait before ordering an invasive lung biopsy

In a clinical study, noninvasive CyPath® Lung test demonstrated 92% sensitivity, 87% specificity and 88% accuracy for detecting lung cancer in small nodules less than 20 millimeters

bioAffinity Technologies, Inc. (Nasdaq: BIAF; BIAFW), a biotechnology company advancing noninvasive diagnostics for lung cancer and other lung diseases, today released a new clinical case study that highlights the benefit of adding CyPath® Lung, a noninvasive test for lung cancer, to the diagnostic pathway for a high-risk patient with multiple pulmonary nodules.

The patient is a 71-year-old former 20-pack-year smoker with a history of pneumonia in the right lower lobe. His current medical condition includes obesity and mild restrictive lung disease. Low dose CT scans revealed scattered pulmonary nodules, with one measuring 7 millimeters (mm), a size that has a greater potential for being cancerous and often leads to invasive bronchoscopy or biopsy.

“Multiple small nodules in a high-risk patient pose a diagnostic challenge, which can be exacerbated by the patient’s understandable anxiety about a potential cancer,” said Daya Nadarajah, MD, the patient’s pulmonologist. “In this case, the patient’s CyPath® Lung result was negative, indicating a low likelihood of malignancy, and together both the patient and I were comfortable in waiting for a follow-up CT scan in three months.”

The follow-up scan in October 2025 showed the suspicious nodules in the right upper lobe had resolved, indicating benign inflammation, and a small nodule located in the fissure between the upper and lower right lobes remained unchanged.

“This is another patient case study that illustrates how CyPath® Lung provides accurate results and greater confidence in pulmonary nodule management, supporting physician decision-making, reducing patient anxiety, and lowering healthcare costs by avoiding expensive, invasive and often risky procedures when they are not necessary,” said Gordon Downie, MD, PhD, Chief Medical Officer of bioAffinity Technologies.

About CyPath® Lung

CyPath® Lung by bioAffinity Technologies is a noninvasive test designed to aid in the early detection of lung cancer in patients at high risk for the disease. CyPath® Lung uses advanced flow cytometry and proprietary artificial intelligence (AI) to identify cell populations in patient sputum that may indicate malignancy. CyPath® Lung incorporates a fluorescent porphyrin that is preferentially taken up by cancer and cancer-related cells. In a clinical study, CyPath® Lung demonstrated 92% sensitivity, 87% specificity and 88% accuracy in detecting lung cancer in patients at high risk for the disease who had small indeterminate lung nodules less than 20 millimeters.
