Early Detection of Recurrent Breast Cancer Using Metabolite Profiling

In her seminar, Leiddy Z. Alvarado talked about using metabolite profiling (or metabolomics)

as an alternative method for the detection of breast cancer. She used nuclear magnetic resonance

(NMR) and mass spectrometry (MS) for analyzing hundreds of small molecules in biological

samples. She could not analyze the biological samples with NMR or MS alone, both had to be

present. She also explained the difference between sensitivity and specificity. Sensitivity refers

to people who have the disease, and specificity refers to people who do not have the disease.

Leiddy explained very well her research and made it very understandable. I loved the idea that

she is one of the authors of the paper we read.
