3-D Model of Breast Cancer in the Lab 71

Posted by ScuttleMonkey from the just-add-water dept.
Roland Piquepaille writes "According to BBC News, U.K. researchers have built a 3-D version of breast cancer in a test tube. Their model contains cells from normal and cancerous breast tissue. The researchers used a collagen gel to form 3-D structures to create structures similar to the ones found in a woman's breast. So far, they focused on a common pre-cancerous condition known as 'ductal carcinoma in situ' (DCIS). With this model, they hope to reduce experiments done on animals such as mice. In fact, these experiments are not always useful because similarities can be poor between mice and humans. Now it remains to be seen if this model will be endorsed by the scientific community."

    Tests on other mammals weren't close enough. So they decided to test on a bunch of 3D meshes.
    That should be close enough to humans.

    Sarcasm aside, 3D simulations can help in areas where animal testing can't, but scientist have assumed too many things in the creation of those models. Nature usually surprises in a ways a model can't predict.

    The tests done on humans during the World War II in the nazi camps were cruel and inhumane. But no one can reject how useful they were in advancing medicine and providing valuable facts about human anatomy and biology, information used widely even today.

    I wonder, could we somehow put the interests of the many before the interests of the one? We're currently eating every day food additives many claim cause cancer. But there's no way to prove it, since causing cancer in test human subjects is illegal.

    Just consider: since testing those substances is illegal, thousands upon thousands probably die from cancer eating basically poisonous food we distribute in our food chains.

        Many of the medicines you use (or people you know use) were tested on humans. If they weren't, those people you know wouldn't be able to take advantage of them.

        The problem with testing for cancer is the dogma that a test that is likely to cause cancer is like intentionally killing a human. Thing is, even with drugs that were tested on humans and not supposed to have serious side eff

      So why do you abstract yourself from these tests, making yourself a third party? After all, you're a thinker, you're not the testee, you're the tester. Right?

      Maybe you should ask yourself if YOU want to be the one the tests are done on. And if you say, "Well, it would benefit everyone else," then you are in serious need of mental help. You should be excited about these models; they can be used

        No. If men were funding breast cancer resarch because they were worried about their women becoming mono-breasted then they'd be even more keen to ensure that they didn't become mono-testicled (assuming the parent means testicular and not prostate cancer). If that was the problem we'd just invent better fake breasts anyway.

        I think Dylan Moran summed up the problem well...

        "A big erm health scare on for men for testicular cancer, now that's a pretty scary thing there... women don't get that so much. And it's a very difficult thing coz you have to look for a lump...in a bag of lumps, and that can take a long time. And you have to do it yourself, because nobody actually wants to touch male genitalia anyway coz it looks like some kind of deep sea fish, you know that became extinct after about an half an hour, it just didn't do very well. And it's a very difficult thing, you have to do it yourself, you have to touch yourself. And as a man you are designed to be aroused by most naturally occurring phenomena on the plant. You know if you see a big bag of wheat or a bit of falling masonry, that can get you going. So...actually to touch yourself can be very dangerous, you can have 38 erections in a half an hour and get a very bad nose bleed. And its extremely important not to tell anybody if you do find one coz you know what will happen, they lift you shoulder high through the streets going "lump, lump, lump!" and throw you in prison. And then little men will come in and beat you with spoons. That's what happens, they cover it up but that's what happens."

        Scary stuff.

        Actually, the usual reason given for the lower funding for prostate cancers is that men, as a generalisation, are less willing to discuss the issues than women. Men tend to shy away from it, and thus it doesn't receive the same level of publicity, ergo not the same level of funding.
        • Men are generally, also unwilling to discuss testicular cancer. Bring it up at the next dinner party you attend. All the males present will flinch and then slowly move away. Same with prostate cancer.

          Because everyone is more comfortable discussing breast cancer, it gets more attention and more funding.
