Area of Science:

• Biomedical Optics
• Medical Diagnostics
• Spectroscopy

Background:

• Cervical and breast cancer detection remains a critical area in women's health.
• Current diagnostic methods have limitations in terms of accuracy, cost, or invasiveness.
• Novel non-invasive techniques are needed to improve early cancer detection rates.

Purpose of the Study:

• To evaluate the efficacy of in vitro Raman spectral analysis of human serum for the simultaneous detection of cervical and breast cancer.
• To assess the diagnostic performance of classification models applied to Raman spectral data.

Main Methods:

• Human serum samples were analyzed using Raman spectroscopy.
• In vitro spectral analysis was performed to capture biochemical fingerprints.
• Machine learning classification models were employed to differentiate between cancer and control groups.

Main Results:

• The proposed Raman spectral analysis approach demonstrated a high classification accuracy of 93% for detecting cervical and breast cancer.
• The study identified specific spectral features associated with the presence of these cancers.

Conclusions:

• In vitro Raman spectral analysis of human serum shows promise as a non-invasive tool for cervical and breast cancer detection.
• Further validation and investigation into potential overestimation in classification models are recommended to ensure clinical reliability.
