Washington: Scientists have come up with an important tool in the fight against the most serious type of skin cancer. Being aware of a patient`s melanoma stage is crucial when it comes to choosing the best course of treatment. When the cancer has progressed to the lymph nodes, a more aggressive treatment is needed. Examining an entire lymph node for cancer takes much effort and time. Now, researchers at University of Missouri are studying how photo acoustics, or a laser-induced ultrasound, could help scientists locate the general area of the lymph node where melanoma cells could be residing. This new technology could help doctors identify the stage of melanoma with more accuracy.
The laser causes the cells to heat and cool rapidly, which makes them expand and contract. This produces a popping noise that special sensors can detect. This method would examine the entire biopsy and identify the general area of the node that has cancer, giving pathologists a better idea of where to look for the cancer.The study was published in the Journal of Biomedical Engineering.
