Developing new methods and approaches for diagnosing cancer and the presence of cancer cells in general, many researchers and technicians often forget that their new approach has objective and very specific flaws and weaknesses. However, given the successes that were achieved by cancer diagnostics specialists from the Kaltek Research Center in the USA, it becomes clear that their research is one of the most promising in this regard. And all because the experts managed to significantly improve the already existing technique of detecting cancer cells in the human body.
This is the so-called PAM scan, which is interpreted as photoacoustic microscopy, which is used directly in the scanning session. Unlike many more traditional and common types of scanning, such as position-emission tomography and fluorescent tomography, PAM scanning involves the use of a laser to induce vibrations and audio waves in a particular study area.
Now, Kaltek specialists have been able to significantly improve this laser diagnosis by adding some additional microscopic sensors that measure the level of absorbed and secreted oxygen by the cells themselves – and cancer cells are known to have a more dynamic metabolism in comparison with healthy cells, which allows us to find them faster with this approach. However, development specialists also say that most likely they will have to reconsider in the very near future an objective approach to the use of such kind of oncological diagnostics, since it also has some weaknesses.
For example, the inability to quickly detect microparticles of cancerous tumors even when using multiple oxygen sensors with PAM scanning. And secondly, specialists need to find a way to reduce the number of oxygen microsensors, ideally creating a pair of sensors that can effectively capture the largest possible area of research of potentially affected areas.
