Scientists have developed a blood test using infrared spectroscopy that may diagnose two types of cancer, lymphoma and melanoma. The findings, published in the journal Scientific Reports, suggest infrared spectroscopy can detect biochemical changes induced by non-Hodgkin's lymphoma, a solid tumorous condition of the immune system, and subcutaneous melanoma, a deadly form of skin cancer. The technique has diagnostic potential as a screening technique for these cancers, according to researchers, including those from Georgia State University in the US.
They used mid-infrared spectroscopy to analyse blood serum derived from experimental mice and differentiate mice with non-Hodgkin's lymphoma and subcutaneous melanoma from healthy mice and also between these two tumorous conditions. The mid-infrared spectral region of the electromagnetic spectrum is frequently used to characterise biological…
