Why is it so hard to cure cancer? – Kyuson Yun


Why is it so difficult to cure cancer? We’ve harnessed electricity, sequenced the human genome, and eradicated small pox. But after billions of dollars in research, we haven’t found a solution for a disease
that affects more than 14 million people and their families at any given time. Cancer arises as normal cells
accumulate mutations. Most of the time,
cells can detect mutations or DNA damage and either fix them or self destruct. However, some mutations allow cancerous
cells to grow unchecked and invade nearby tissues, or even metastasize to distant organs. Cancers become almost incurable
once they metastasize. And cancer is incredibly complex. It’s not just one disease. There are more than 100 different types and we don’t have a magic bullet
that can cure all of them. For most cancers, treatments usually include
a combination of surgery to remove tumors and radiation and chemotherapy
to kill any cancerous cells left behind. Hormone therapies, immunotherapy, and targeted treatments tailored
for a specific type of cancer are sometimes used, too. In many cases,
these treatments are effective and the patient becomes cancer-free. But they’re very far from 100% effective
100% of the time. So what would we have to do to find cures
for all the different forms of cancer? We’re beginning to understand a few
of the problems scientists would have to solve. First of all, we need new, better ways
of studying cancer. Most cancer treatments are developed
using cell lines grown in labs from cultures of human tumors. These cultured cells have given us
critical insights about cancer genetics and biology, but they lack much of the complexity
of a tumor in an actual living organism. It’s frequently the case that new drugs,
which work on these lab-grown cells, will fail in clinical trials
with real patients. One of the complexities
of aggressive tumors is that they can have multiple populations
of slightly different cancerous cells. Over time, distinct genetic mutations
accumulate in cells in different parts of the tumor,
giving rise to unique subclones. For example, aggressive brain tumors
called glioblastomas can have as many as six different
subclones in a single patient. This is called clonal heterogeneity, and it makes treatment difficult because
a drug that works on one subclone may have no effect on another. Here’s another challenge. A tumor is a dynamic
interconnected ecosystem where cancer cells constantly
communicate with each other and with healthy cells nearby. They can induce normal cells to form
blood vessels that feed the tumor and remove waste products. They can also interact
with the immune system to actually suppress its function, keeping it from recognizing
or destroying the cancer. If we could learn how to shut down
these lines of communication, we’d have a better shot at vanquishing
a tumor permanently. Additionally, mounting evidence suggests we’ll need to figure out how to eradicate
cancer stem cells. These are rare but seem
to have special properties that make them resistant
to chemotherapy and radiation. In theory, even if the rest of the tumor
shrinks beyond detection during treatment, a single residual cancer stem cell
could seed the growth of a new tumor. Figuring out how to target
these stubborn cells might help prevent cancers
from coming back. Even if we solved those problems,
we might face new ones. Cancer cells are masters of adaptation, adjusting their molecular and cellular
characteristics to survive under stress. When they’re bombarded by radiation
or chemotherapy, some cancer cells can effectively
switch on protective shields against whatever’s attacking them
by changing their gene expression. Malignant cancers are complex systems
that constantly evolve and adapt. To defeat them, we need to find
experimental systems that match their complexity, and monitoring and treatment options
that can adjust as the cancer changes. But the good news is
we’re making progress. Even with all we don’t know, the average mortality rate
for most kinds of cancer has dropped significantly since the 1970s
and is still falling. We’re learning more every day, and each new piece of information gives
us one more tool to add to our arsenal.

  1. Cancer is an extremely difficult disease, and the only hope we have to cure it is to understand it. If you'd like to get up to speed on where we are in this journey, the book we recommend at the end of this video is a great place to start. You can download a free audiobook at http://adbl.co/2gauxND. And for even more book recs from our team, visit http://bit.ly/2wKOs9c.

  2. It will never be cured while big pharma holds the licensing for cancer treatment they would not allow it when it makes them 40 billion a year, there has been cures which they just shut them down

  3. there's no cure because there's so much more money to be made in researching and treating a disease than actually curing it. and don't you think i'm crazy for saying that. no one has cured anything in years, if not decades. i have every right to think what i just wrote.

  4. It’s not. The reason it’s “difficult” is because as long as Cancer exist medicine companies keep making money…..

    Ps. Every disease has a cure

  5. The cure for cancer is very early detection. Which would only be possible with socialized healthcare where everyone gets tested frequently.

  6. A cure for cancer isn't the objective, a money making drug or medicine to prescribe for cancer patients is the objective. Any cures discovered are thrown out if a drug isn't able to be created from the discovery. It's all about money folks.

  7. The question is where does cancer cells come from? Infections from a virus? If so, defeat the virus that cause this cell to change. If its not a virus, then its a mutation, in which that is why its hard to detect or cure as it still shares the host cellular properties and the host nurture and provides to its continue survival. Perhaps this is how evolution of cells come from and how we humans became humans or how many other animals, plants and other organisms became what it is. I believe studying how cancer is able to change other cells to become something that its not originally design maybe the key to medical breakthrough. Like making a failing liver to make it healthy or self repairing. If a cancer cell can change nearby cells or duplicate cells using the host cells to replicate, isn't that like self healing? Then again, like a coin, there are 2 sides. This can also comes to an end in the dark side. We may all become zombies due to this uncontrollable cells taking over or become mutants with superpowers.. Time will tell.

  8. I encourage everyone interested to donate their computing power via BOINC software.
    Your computer participates in a pool of computers all sharing their processing power to help scientist teams make large scale calculations on various projects, as would a super-computer do.

    Among current projects:

    – Smash Childhood cancer
    – Microbiome immunity project
    – Mapping Cancer Makers
    – …

  9. because they want people to have cancer. That's why they poison all the food with chemicals. They make $BILLIONS selling the "treatment"

  10. Quran say (Muslims holy book) : Allah (God) never gave disease without already have the medicine to cure it "in nature", cancer cure medicine already exists in nature, but we don't know it yet, we have to search for it and find it, this is true and we believe in it.

  11. Im a cancer survivor!!! Cancer is freaking HARD!!!!! ALWAYS BE A REAL FRIEND IF YOU KNOW SOMEONE WHO HAS CANCER!!!! THEY REALLY NEED YOU DURING THAT HARD TIME.

  12. The reason why cancer hasn’t been cured? Big Pharmacy and Hospitals make big money off patients. It’s more profitable to them if you stay sick. That’s why.

  13. Here! 2 teaspoons of baking soda,1 teaspoon of mollasses,1 cup of water,drink it warm. Repeat every day as needed.Get plenty of sunshine on your skin to produce vitemin d3,also google "Dr. Batman"(not joking).Google-coral calcium & chemist Robert Barefoot and youtube-italian docter uses baking soda to cure cancer.Hope this helps.

  14. Well that’s a simple question to ask… it’s a multi billion dollar industry. They don’t want you to find the cure for cancer or HIV/AIDS. If you cure it no more money $$$

  15. Keep your PH at 8 or slightly higher. Cancer requires acid to live. A PH that is slightly alkaline will kill the cancer cells and prohibit any new cancer cells from forming. PH 7 is normal. PH test strips are sold at WalMart..

  16. it is difficult because so many people get so fkg rich and there is no way they are willing to give up their wealth source.

  17. Cancer is hard to cure,because it is an
    Abnormal Disease within the body.It can
    affect any part of the body.You get
    cancerous cells.The Question is what
    causes these cells to occur in the first
    place.Could it be the defensive system
    in the body that cannot protect us.It
    could be that these cells are immune
    to our defensive system.There needs
    more research into this matter.

  18. Radiation And Chemo WILL NOT BE EFFECTIVE FOR LONG.. BIO-THERAPY IS THE ONLY WAY TO DEFEAT CANCER ONCE AND FOR ALL.. Starting With The T-4 Cell.. There's NO OTHER OPTIONS.. There Will Have To Be Developed T-4 CELLS That Specifically Seek Out And Destroy CANCER CELLS At Their Most Basic Genetic Level.. T-4 Cells That Directly Attack The Make Up Of The Cancer Cell.. And, NOT THE CANCER CELL ITSELF.. Elaboration.. T-4 Cells Cultured To, And Developed To, Destroy THE GENETIC MAKE UP Of The Cancel Cell..

    T-4 Cells SPECIFICALLY DESIGNED To Seek Out. Connect To/Infiltrate The Cancer Cell. And Then Destroy It From Within The Cancer Cell.. We May Even Have To Use MODIFIED/CROSS BRED T-4 CELLS AND CANCERS CELLS Which Have Been Basically Reprogrammed To Allow The New Modified T-4 CELLS To Connect To And Destroy The Cancer Cells FROM WITHIN… A "Trojan Horse" T-4 Cell.. So To Speak… The Question Now Is.. CAN IT BE DONE…

  19. There is a cure but they dnt want to cure it because it's big business……
    Cancer ïs causen by the kind of food we eat and lock of certain vitamin in the body…..

  20. Chew carefully raw vegetables, whole grain to secrete more enzymes and eliminate acid from our cells. That’s the key to alkaline body and wake up protect gene also cytokine system work efectively. should not eat animal because it make acid enviroment and cytotoxic.

  21. Hearing that metastasised cancers are almost incurable really knocked the wind out of me.

    My grandad has just been diagnosed with Stage 4 metastasised stomach cancer.

  22. Because it is suppressed so by Big Pharma that sells drugs to Blanket it versus cure it. Having sick people with bogus drugs, MAKES MONEY !!!! Where is the Human Soul in Big Pharma ??? Wake up. Pharma is not your Friend…..

  23. I find it hard to believe that Cancer is self forming and that we have such a self-destruction coded just waiting to essentially be triggered…what's wrong with that story? We should start by getting rid of the poisons in our food and water. We can start with fluoride and aluminum as they have NO purpose and CANNOT be justified

  24. The only standing in the way of an actual cure to cancer is the corrupt monetary profit motive. All the money being generated in the for profit cancer research INDUSTRY is in the continuous expensive cancer treatments. Not the actual cure. Because if the cancer research industry was actually in the business of finding the actual cancer cure/ solution. They would be in the business of putting themselves out of business.

  25. I lost my only sister today from cancer 😢😢 she died a slow agonising death …she gave up ..The pain was so unbearable .. I hope my heart heals ….she resting now …no more pain n worries .

  26. People don’t realize that even if your the healthiest person alive, you still have a chance of getting these disease. The only thing we can do is lower the chances.

  27. Just found out today that my mum has Multiple myeloma in her lower back and it’s fast spreading. Tbh I’m terrified about what’s going to happen.🥺

  28. Cancer will likely never be cured it's not that there is no cure because there likely is obviously but they won't release it because of money

  29. Thank you for sharing this. This article also provides a great summary of what we know so far about cancer, which is hopefully bringing us ever nearer to a cure. https://www.careworkshealthservices.com/caring-for-cancer/

  30. It's sad people are still promoting the lie of "no cure for cancer" here we are getting information from a damn animation video smh, if you don't know about the burzenski case you don't know whats really going on, and thats just the tip of the ice berg

  31. Too much philosophy about the disease and rarely about healthy ways of eating, living, avoiding toxic medications, polluted environment etc. Cancer is a product of bad lifestyle.

  32. There are many cures for cancer, but they are kept from all because there is no profit in curing it. Also every person is different and uniquely put together. There will never be one cure for cancer, modern medicine is a misinformed and under educated group of doctors who do not look at the big picture.

  33. Going on a no sugar diet literally starves the cancer. My mom knows someone who over came cancer several times with her no sugar diet

    I believe they do know a cure but the world is corrupt….. :/

  34. I think it will be cured when the people that say it can't be done get out of the way of the people doing it. Billions of dollars all going to the cause of the human cell mutation. What if the human cell isn't mutating and we are dealing with a parasitic mycilium. If it's not, why would a mass of mutated HUMAN cells be destroyed by anything anti fungal. I've seen it destroyed by CHAGA mushroom and I've been studying this mushroom for 7 years now. I've heard of the effects of TURKEY TAIL and red reshi also. This disconnection appears to me to be deliberate.

  35. I think i going to have a colon cancer😭 and i feel bad for myself.😭 i don't want to die😭 Please Pray For me😭 Its a BIG HELP for me. I haven't consult a doctor yet😢 I don't wanna die, i want to live longer. Until my last breath😭 i want to achieve my DREAMS in my LIFE so Please Pray FOR MEEE😭😭😭 I don't want to. I'm not Joking its not a joke. We don't have enough money to afford. Were not Rich If i had 1 wish, just 1 wish. I Want to live A Longer Life😭 and with my FAMILY I WANT TO STAY WITH THEM. And i want to live a longer life. So Please, please. Pray For me please? Anyone?😭 1 pray for me is a BIG HELP. 🙂😭😢
    From:Philppines.
    Philippines is not a Rich Country. Many of us is Poor.

  36. There isxone animal that never gets cancer? Who is it? The shark. Why because its body is made from cartalidge. You might want to look into it.

  37. the question is why dont they want to release the cure,big money is made on cancer, kill the greed , find the cure

  38. if you broke u die,only the rich live for threatments n pills, sick world, cancer patients walk in hospitals and first thing they look at is their wallet , if you are broke they send you home packing saying you have this amount of time to live , sick governments sick doctors , this world is sick

  39. ITS MORE ABOUT HOW TO PROFIT FROM YOUR CANCER THAN IT IS TO SAVING LIVES , HOW ARE NORMAL PEOPLE SUPPOSE TO FIGHT IT>?? WHEN THE AVERAGE COSTS FOR TREATMENT RISE TO 150 THOUSAND A YEAR OR 12 THOUSAND A MONTH FOR ONLY ONE DRUG. THIS IS A SICKENING WORLD WE LIVE IN , ALL DOCTORS AND SCIENTIST SHOULD BE DISGUSTED WITH THEMSELVES FOR ALLOW DRUG COMPANIES AND HOSPITALS TO DO THIS. CANCER IS ABOUT IF YOU HAVE MONEY WE HAVE THE TREATMENT , MONEY MAKING CASH MACHINE AND THEY MAKE BILLIONS OF PEOPLE . HUMANITY IS BEYOND SAVING, IF YOUR NOT A MILLIONAIRE OR RICH YOU HAVE TO WATCH FAMILY DIE , I HOPE A PLAGUE COMES AND WIPES OUT HALF THE WORLDS POPULATION SO WE CAN START OVER

  40. Cancer is one of the easiest things in the world to cure!!  There are nearly 400 KNOWN NATURAL cures for it and some of them you can buy in your grocery store for a couple dollars!!  So far, this is the best cure I've found.  https://youtu.be/Yti2w1hBcZg

  41. https://www.youtube.com/watch?v=GLGieyWlU8g my video about….
    You rarely die of cancer itself, you die from the chemical treatments… Get some knowledge docu series "the truth about cancer". YOU don't have to die!!!

  42. Amygdalin, laiatril, vitamin b17, apricot kernels etc.!!!!! Cheap and never fail if administrated in time, I mean not after experimenting with radiation and chimo..wake up people. They want your money, and those that have lot sof money want you dead. It's that simple
