Non-invasive detection of breast cancer can be performed by detecting the increased concentration of _________ in a breath sample.
Methane
Pentane
Acetone
Ethanol
Can you please post any work you have done for all of the questions you posted? Thank you.
after deep analysis i found pentane would be tte answer since its onlt non toxic gases amoung four.am i right?
To determine the non-invasive detection of breast cancer by detecting the increased concentration of a particular substance in a breath sample, we can look at several possibilities. Methane, pentane, acetone, and ethanol are all substances that have been studied in relation to breath analysis for medical purposes, including the detection of cancer.
However, in the case of breast cancer, the substance that has received the most attention is acetone. Acetone is a volatile organic compound (VOC) that can be detected in breath samples. Research has shown that there is an increased concentration of acetone in the breath of individuals with breast cancer compared to those without the disease.
To determine the increased concentration of acetone in a breath sample, analytical methods like gas chromatography-mass spectrometry (GC-MS) are typically used. GC-MS allows for the separation and identification of different compounds present in the breath sample.
It is worth noting that the detection of cancer through breath analysis is an area of active research and development. While some studies have shown promise in using acetone concentration as a biomarker for breast cancer, further research and validation are still needed before it can be widely implemented as a diagnostic tool.
