    Possible cure. Remember Nixon's War on Cancer

    It is early days yet but a research team from the University of Coimbra in Portugal has announced this week that a first clinical trial on human subjects has revealed positive results in treating cancer of the head and neck - and in one case the tumor disappeared completely.

    It is called photodynamic therapy. The molecule, redaporphine, was developed by a research team of the University of Coimbra. It is activated by infrared light and when it comes into contact with oxygen it produces other molecules which destroy all the tissues around it, so it can be steered directly to the tumor it is targeting and the dosage is adjusted to the level of highest efficiency. The molecule then springs into action, destroying the tumor but not the healthy tissue surrpunding it.

    Patient in palliative care sees tumor disappear
    The trials were conducted on a group of fourteen patients with advanced head and neck cancer, over two years. The most remarkable result was that of a patient who was already so ill he was in palliative care - and the tumor disapeared completely.

    That's a pretty clever way of localizing the effect, using infrared as activator.

    I lost a lot of loved ones in cancer. I hope this is true.

    The research has been ongoing for quite some time, that part is true. That it is a "cure for cancer" has not been proven - especially for such a small study and only one success out of fourteen cases.

    I have cancer and have lost loved ones to it.

    I saw this and looked it up here: https://en.wikipedia.org/wiki/Photodynamic_therapy

    It seems to be a well-known, if still new, therapy that relies on stimulating a molecule into a state with unpaired electrons (a "triplet"), which can react as a free radical and generate unstable species that kill cells. The article is long on photochemistry but unfortunately short on what it is that makes the photosensitive agent accumulate predominantly in cancer cells, which is obviously key to any success in cancer treatment.

    Unsurprisingly, Pravda (yes, really, that's where the OP got his info) was not very helpful on that score either.........

    Try to find molecule developed in Portugal. (redaporphine,) which react with infrared band

    OK here is a link to what looks like the real thing: https://estudogeral.sib.uc.pt/jspui/handle/10316/29825

    The name they have given to the molecule is actually spelt "redaporfin", not "redaporphine".

    I quote a line from the abstract: "This work describes the nonclinical development of a new fluorinated sulfonamide bacteriochlorin, redaporfin, with very promising properties for anticancer PDT: simple and affordable synthesis, high purity and stability, molar absorptivity of 140000 M–1cm–1 at 743 nm, high quantum yields of ROS formation, photostability, solubility in biocompatible formulations, low toxicity in the dark and high phototoxicity. "

    However I can find no reference to any publication of results of human trials of this substance.

    I also note that the links in the Pravda article you provided take the reader to irrelevant topics: a pack of lies about NATO and something about soccer. So as expected there is a fake news component to the Pravda article. I would not take it at face value.

    I don't take Pravda seriously, but the is always something open my eyes.

    I agree on Pravda. Especially Putin's Pravda. Nothing quite like that combo of old-style KGB and the Russian Mafia.

    We have not reached a point at which we can say that a "cure" for cancer has been discovered. Nonetheless, many treatments have been developed that greatly increase the life expectancy of cancer patients.

    Chemotherapy has been used for decades to kill cancer cells. Unfortunately, it has a terrible side-effect: such bad nausea that makes the patient almost incapable of eating. Intravenous feeding is simply not a long-term strategy. Fortunately, now that marijuana is in the process of decriminalization, chemotherapy patients can use it to overcome the nausea and increase their appetite. (Or as it's commonly called: "the munchies.")

    A couple I knew 25 years ago had a son who was dying from cancer and starving from chemotherapy. They planted a marijuana garden in their backyard and, last I heard, he had lived fifteen more years. Yes, the neighbors and even the police knew about it, but they loved the kid so they all just looked the other way.

    I think you will find that control of nausea and other side effects of chemo has advanced considerably in the last couple of decades. My wife died of ovarian cancer last summer, having had it for seven years, during which she went through 6 different courses of chemo, involving 5 different agents. In all cases the nausea was so well-controlled that she was able to function almost normally, and barely lost a day's work until the last 3 months. And she didn't smoke anything!

    I got the chemo nausea side effects immediately, usually during breakfast in the morning. :barf: I use a Pax portable vaporizer, no smoking anything ever. The nausea attacks have faded, haven't had one in a month now. Am not looking forward to going back into chemo, but will do what I have to to stay alive a while longer.

    My Labs vet has ovarian cancer, got spayed a while back and got chemo as well. Her hair has just grown back so we shared a minute of being happy between treatments. Neither of us has been 'cured' though, so we know it is just a matter of time.

    ...as it is for all of us.....but the issue I guess is how much.

    They are working on nano technology to create millions of seek and destroy cancerous cells nano missile.
    Of interest may be that bee venom is an excellent cancer cell killer, unfortunately is it is just as effective on healthy cells, which makes it mandatory to deliver the toxin to the cell itself. Remarkable stuff.

    The entire clip is enjoyable and informative, but if you want to see the bee venom segment go to 45:00 setting.

    Fascinating video and technology, thanks.

    I sincerely hope that they can get it to work...soon. While I can most likely kick the can down the road a bit further with 1st round chemo and then 2nd, 3rd....it would sure be nice to be rid of this crap and not have to think about it any more.

    'Course, I am also allergic to honey bee stings.......

    I'm sure that when they succeed in finding the cure for cancer, the first place they'll publish it is on SciForums. So I strongly recommend that you remind all of your friends and neighbors to keep up with this website everyday, so they don't miss the wonderful news!

    Depends on the cancer, the stage and the chemo.

    I am optimistic that one of these new directions in research will give us a breakthrough, mostly as there is a bunch of them in process and there have been some serious progress.
