Researchers typically use a standard insulin syringe, which is small and has a very fine gauge needle (usually 29-31g)
These findings collectively underscore the critical role of parameter optimization-from alternating magnetic fields enhancing radiotherapy [14] to focused ultrasound-ethanol combinations suppressing metastatic phenotypes [18] -in balancing oncogenic risks against therapeutic precision, highlighting the need for rigorous control of frequency, intensity, and duration
That doesn't mean it has never happened, just that if it has, it must have been a very rare and drastic case
