After watching how the human body gets resistant to chemotherapy, radiation, and other anti-cancer agents, wouldn’t someone have to keep getting radio frequency and nanoparticle treatments forever and wouldn’t the body finally get resistant to this? Do we have even one case of cancer cured in animals with this method?
If there really were no side effects, having to keep going in wouldn't matter :) People could go in every 3 months or whatever for a prophylactic nano/RF treatment just to clean themselves out. Like getting a regular teeth-cleaning. Big deal. Much better than going to radiation/chemo... and having recurrences...
And too much cost? But if this really works, we're gonna stop spending countless billions on chemo and radiation equipment and supplies and research (and put some big corporations out of business, and medical workers out of work along the way)... so we'll have plenty.
As for resistance: the resistance sometimes seen to e.g. radiation treatments has specific biological causes, like hypoxia... and/or the radiation kills many of the cancer cells but not all, those left behind recover (and you can't keep going forever because after some threshold you'll cause complications in normal tissue, so some fraction of cancer is inevitably left behind)... But perhaps with this nano/RF treatment, there's no parallel to any of that. If the RF waves go through the whole body with equal strength, if the nanoparticles can "tag" any cancer cells no matter where they are (with an efficiency that's indifferent to biological variations such as hypoxia), if the fraction of cancer cells killed by an RF treatment is essentially 100%, etc., then maybe there'd be no equivalent of the resistance seen with radiation.
But yeah, there are some ifs involved. For one thing I still don't understand how you can possibly engineer (what I gather are) RF-sensitive nanoparticles capable of finding & attaching themselves to the category "any cancer cell". (1) that's a big category, cancer cells come in wide variety. (2) even in a specific *type* of cancer cell (which is probably what they envision doing - use nanos X to find the pancreatic cancers, use nanos Y to find the breast cancers, etc), it's hard to fathom being confident the nanoparticles will find each and every one of them, if you have to rely on the bloodstream, or diffusion, or something like that to spread those nanos. Some cancer cells would inevitably get lucky and successfully hide from the nano cancer-cell-dragnet, I'd think... (unless it doesn't matter as long as 99.9% are found?)
But maybe I've misunderstood. Either way, there's a lot of details swept under that rug I imagine.
