  • not cure... but prevention.... we have to watch our lifestyle.. and be more responsible with our Body.

  • i didn't smoke its because of air polution :(

  • ;((( PRAYING FOR THOSE ONES WITH CANCER!!!!! <33333 D';

  • Right now i'm having lung cancer....

    its horrible i would love to die then live with this disease till the death....

    wish me luck :(

  • @MsRsclips it is your fault for smoking.

  • @MsRsclips After reading your comment i pray and sincerely wish that your Cancer causes you an excruciatingly painful, slow and miserable death.

  • THE HIDDEN CURE. Cancer is a chronic metobolic disease caused by a dietary deficiency of nitrilosides found in bitter fruit seeds and other unpopular foods just like scurvy is a deficiency of vit C - This was discovered in 1952- Big Pharma / FDA racketeers covered up the cure and declared it fraud and quackery. Watch A WORLD WITHOUT CANCER Video and investigate. Many lives have been saved just by adding this to the diet.Keep away from the drug racketeers and get cured.

  • @Tealy855 Bullshit. Don't even say something like that. If a cure existed, companies would fucking trip over each other to be the first to get it out. Do you have any idea how popular and renowned a company would be if it was THE one to cure cancer? Your arrogance to claim a simple "repressed" cure exists offends me, and it offends the memory of every family member of mine who has died of cancer and who lives with it today.

  • @Anonie324 "My wife did take B17, high doses of Vitamin C and did NOT take any radiation or chemo and she has been alive and cancer free for 3 years after stage 2/3 breast cancer. Of course the medical Dr. in our country said masectomy and chemo+raidation was the only way to survive. The older I get, the less I believe what is the so called truth from our so called leaders. I don't really find this funny, better words might be close minded." sonFreeman.///

  • @Anonie324 This is natural and anything in nature cant be patented, therefore no money can be made from it.Thus we have a 60 year supression - I personaly know several who have been cured by (B17) - some went to the clinics in Mexico- I have first read the book ALIVE AND WELL by Philip E. Binzel, Jr., M.D.(free download) and watched the video A WORLD WITHOUT CANCER ( youtube) tells the whole story- during the same time I too have witnessed many more who have died from the chemo and radiation.

  • @Anonie324 Thats "ALIVE AND WELL by Philip E. Binzel, Jr., M.D Whale" for the free book

  • thanks.

  • Your videos and presentation style is so amazing. You are a natural born teacher. Do the world a favor... DON'T QUIT!

  • can u do a video on the full process of apoptosis and necrosis, outlining differences

  • "conlact ihhihu"

    Wow.

    Love you Sal, but wow.

  • Terrible disease!

  • If you have cancer or someone u know do not worry I discovered something 2 heel it just send me a message on YouTube and I will let ya know what u need to do

  • WOW! This is sooooooooo helpful!!

  • @MegaBreyergirl IKR I Use Khans for school =D

  • @20000surfsup

    LOL! Me too!

  • thank you for helping me understand what cancer is and what it does. my class tries to make a regular basis of your website.

  • ang tao ra ang naghimo sa iyang sakit...pwde man maprevent na dili magkasakit, depende na sa tawo unsa niya pagdala iya kaugalingon.

  • 0:40 were those cells making trouble in the neighborhood?

  • 100 Likes, if you wish cancer did not exist

  • Meh-taa-stay-sigh-zzed !

    

  • THey kill themsleves! What great citizens.... wow.....

  • hm.... 7 billion humans! 3:35

  • does fat cells selfdestruct on error? (apoptosis) 2:30

  • .. the reason i chose to do biology. im still 16 so i got a long road to go, but this might be a way for me to have any influence in the world. (:

  • Cellular psychopath lol I was thinking hulk mode xD

  • Interesting video!

  • gotta say, you have got to be the greatest teacher in the world

  • Cancer is a disease caused by a dietary deficiency of nitrilosides/Amygdalin found in seeds and other

    unpopular foods just like scurvy is a deficiency of vitamin C - This was

    discovered in 1952- Big pharma / FDA covered up the cure and declared it fraud and quackery.

    Watch World Without Cancer Video and investigate. Many lives have been saved just by modifying diet and

    just saying no thank you to the Big pharma / FDA chemo/ radiation rackett .

  • nice

    

  • What causes Photo-oncogenes? I thought that any DNA changes were inherited from the parents? Or can they be affected by outside factors (radiation, carcinogens, etc.)? Future oncologist here, so I really would like to know.

  • This is great video! I really didn't know anything about tumors...Great, great! Thank you, Sal!

  • cancer has been one of the serious medical condition especially in my country Kenya. working in public facilities have made me learn more. The problems we are facing are: lack of information about cancer,inadequate diagnostic facilities doctors.

    The information you are giving will enrich people in terms of knowledge and take appropriate measure in controlling its menace.

  • Sheeitt Kahn knows everything...

  • Cellular Psychopath :D

  • Will i get a claw like x-man if i got cancers? Is that possible? LOL

  • @kalepensel no... generally you'd just... die... o.O

  • cannabis cures cancer...Watch"RUN FROM THE CURE" it is uploaded on youtube

  • Really helpful video!!!

  • cellular psychopath lol'd when you said that

  • good teacher! thanks,

  • Terry Fox

    Please support his Marathon of Hope.

    

  • 6 people have not seen the george and sherlock cancer story video

  • Cell citizens, cell psychopaths, thanks for making me imagine cells as little people that either commit suicide or are very rude. Love your videos.

  • Cancer: A disease I'm all too familiar with. Lost both of my paternal grandparents, my uncle, and my mother, all to cancer. My husband also lost his grandfather to it, last year. NOW....my maternal grandfather was just diagnosed and there's no hope for him, in addition to another one of my uncles, who is currently fighting it. So basically, it's wiping my family out, one by one. We need to find a cure for this damned disease, and we need it NOW!

  • @babygiraffe123 google ( electrical properties of cancer cells ) i live in ireland what i read hear is the FDA is corrupt. cancer treatment is a trillion $ a year industry. nature is savage. look at the movie lorenzo oil .it's inspiring. allso google ( testimonies to laetrile )

  • @babygiraffe123 lost both of my grandparents to cancer two :(

    seriusly we nead a cure!

  • Comment removed

  • @babygiraffe123

    Sorry, but two critical points you must know if you don't already. 1) Merck, GSK, Pfizer, etc (Big Pharma) would not let this happen in a million years. If they can make $30,000 from chemotherapy drugs, do you really think they wan't to "cure" cancer? No, it's harsh but there are approx. 7,000,000,000 so what difference is 1 person gone? It's insignificant. We are nothing. Secondly since there are many different types of cancer, it's irrational to say "a cure for cancer".

  • @jumb0mumb0 finally someone gets it.

  • @babygiraffe123 Weed kills cancer cells. Just sayin.

  • Cure for cancer with no side effect /watch?v=H0ibsoqjPac

  • I don't know why these fuckers with cancer just don't stop whining and stop sucking -.- only the weak get cancer, i've got it before and i just told it to fuck off and it did. Thats called manliness.

  • Cancer cells avoid immune destruction either because they don't change their ID, they develop some other "stealth" ways, they use decoys or they simply divide so fast that the immune system cannot cope with that It's a real war and war strategies what gives cancer its growth and final defeat over the human body We must find ways to kill it or prevent it, like we did with some viruses with the help of the vaccines Sure we need to undestand the enemy and this video helps us a little bit, good job!

  • You can actually help work towards a cure for cancer and many other diseases by watching the video on my channel. Your computer can actually be used as a scientific research tool.

  • IMPORTANT!

    The producers of this powerful film are allowing a full and FREE preview through June 13th! Please tell everyone you know to watch this film in it's entirety through June 13, 2011.

    This is the story of a medical doctor and Ph.D biochemist named Dr. Stanislaw Burzynski who won the largest, most convoluted, and intriguing legal battle against the Food and Drug Administration in American history.

    Google this!

    "Burzynski The Movie - Cancer Is Serious Business"

    Pass it on!!

  • It is a great video, it gives me an idea about the implication of tumour.  I realy enjoyed watching it.

  • It is a great video, it gives me an idea about the implication of tumour. I realy enjoyed watching it.

  • cancer is a funny disease that makes old ugly people look even uglier by making them go bald then killing them LOL

  • I had to watch this in my year 7 science class the other day!

  • i knew nothing about cancer when the doctor told my wife she had pancreas cancer all i knew was that he told her that she needed surgery right away or she would pie a slow painfull death and no one wants to see a loved one die the kind of death he said she would die but know i wish that i would have told him to kiss off

  • I think it shows how simple cancer can be explained i already had good knowledge of cancer before watching this but it shows easy to explain and we know exactly what we are dealing with and how difficult the solution is/are. Because its our own body not some foreign entity effecting the body but our cells mulfunctioning.

  • i type in cancer and i get videos of some screamo metal band.

  • neoplasm neoplasm...neeeooplasmmm. really chewing on your words eh?

  • R.I.P Molly! My Dog :( She had Lymphoma

  • @wordbird1 I had a dog named Molly too, she just passed away yesterday, she had Lymphoma as well.

  • @Gejorotto

    What kind of dog? :'(

  • Oh nevermind, my bad. I'm just tired, lol.

  • Is 100 trillion not 1000 billion?

  • @Gabumon54321 1 trillion is 1000 billion. 100 trillion is 100,000 billion.

  • The Cure for Cancer is Chuck Norris's tears too bad he doesnt cry much. 

  • i don't know what's more interesting, this video or the fact that CANNABIS kills cancer cell growth ? u decide ! :) hemp will help save the planet whereas cannabis (don't get me wrong, it's the same shit only more active substances) will help cure sick people even terminal cancer patients... take a look at my channel, and u'll all see great documentaries ! :)

  • Why not use a retrovirus to reintroduce the self-destruct mechanisme?

  • Thanks for sharing this. You made Cancer a lot easier for me to understand better on how it starts with the growth of the healthy cells and unhealthy cells by simplifying it.

  • A really good overview of cancer! be careful about saying benign neoplasms aren't dangerous- they can still cause problems through local invasion & pressure, hormone synthesis, etc.

    Thanks Khan

    :-).

  • I hate cancer.

  • How is apoptosis different from phagocytosis??

  • @kpaniracrbk

    hi.

    apoptosis is programmed cell death. it is mediated by the cell due to either intrinsic (within the cell) or extrinsic (outside the cell) signals. proteins are broken around but importantly the cell membrane remains intact- "blebs" are given off which are then "phargocytosed" by phagocytes.

    Phagocytosis is the process by which phagocytes (cells of the immune system) remove & destroy bacteria, viruses, fungi, and our own cells from the enviroment.

    Hope that helps? M

    I have been VOLUNTEERING with the Cure Drive almost 20 years. Cured my own herpes - 2 kinds - HSV-1 and 2-- got it in '66 -- 28 years of outbreaks. I have helped people cure cancer, Graves' disease, lupus, CFS, fibromyalgia, FLU, many others - the main movie on CureDrive's Channel is me helping someone cure LEUKEMIA. Call me - I will help you - I'm Bayard Henry Barnes on Facebook.

  • swallow your spit!!. arghh. can't stand this

  • 0:23 SMILY FACE

  • This is serious... The answer for a cure is right under our noses and no seems to know. I watched a documentry recently called Healing Cancer From Inside Out and found information that everyone needs to know about cancer. It's upto you to educate yourself and learn many reasons why the system has not let the people know what they can do to heal cancer and prevent cancer.

  • @Ericshun6969 and what is it?

  • amazing thank you

  • Cancer is a joke...People need to grow up and stop bitching..."wah i have cancer" get over it...Take some tylenol and walk it off you fat whores.

  • @Lolatcancer dude or dudette-quite possibly, u need to stop trolling here, millions of people die of cancer every year and millions more are affected by it-it's not a joke. u need to grow up and mature abit AND unwad ur panties here son, i'm pretty sure if it happened to ur mother or father or somebody u cared about u wouldn't go online and joke about it-grow a pair.

  • "If you have a lump..God forbid if you have a lump either way...it can kinda stick around, no damage done"

    "..grow like crazy"

    "..some sort of cellular psychopath" <--- LOL

    I don't know why I found what he said funny. =='

  • wow u r good !

    lol @ cnt say metastasized coz i think somethings wrong wth my brain

  • actually weed cures cancer, but its illegal. the things that cause cancers are legal. So in fact all those stupid people who do the walk for cancer are wasting their time because they've been brain washed to think weed is harmful to people. Welcome to 1984 my friends :D

  • @127miles You can't be seriously saying that Cannabis is NOT harmful to the human body? Are you absolutely ludicrous? Go educate yourself.

  • @LowCaffeine You're argument is invalid. Support it with at least a few facts that Cannabis is harmful to you're body. GO SMOKE SOME FOR FUCK SAKE.

  • Lack of aptosis seams to be the problem.

    If you can find a treatment that can kill cells that does not have the aptosis gene functioning, then you can cure cancer.

    But how can that be done? The aptosis gene doesn't give off a protein market on it's cellular membrane does it? If it did, then you can create a treatment based on that.

    The only way I can think of, is engineering a virus with the aptosis gene that inserts that gene.

  • @Chnamanjx

    The only way I can think of, is engineering a virus with the aptosis gene that inserts that gene.

    My first Idea as i watched this video, too :)

  • @Chnamanjx

    clever idea hmmm

  • @Chnamanjx Genius? 

  • @Chnamanjx doctors are engineering vaccines that make our defense system realized the mutated cancer cells and kill them. Pardon my English.

  • @Chnamanjx Yes, you are right, but inserting the apoptosis gene to all cancer cells is harder. If you insert the gene to normal cells, the normal cells may die early, too bad :(

  • @Chnamanjx

    problem with that is, that there is no single "apoptosis-gene". this process is highly regulated and controlled by a number of different factors.

  • @Chnamanjx That's the solution, gene therapy.

  • @Chnamanjx yes, but how are you supposed to do that when there is a huge number of cells? And if you dont insert the gene in one of the cells, it will keep on duplicating, and it just keeps on growing.

  • carcinogens Look them up...and avoid them... I think the world should come up with alternative methods to get things done and rid the world of all

    carcinogens When human kind stops worrying about winning the war and concentrates on preventing a war, the fight would be won, because there would be no fight.

  • Thank you doctor. I wish i could get you as biology professor. your explanations are very clear and way understandable compared to that of my professor. Good job!!

  • great video

  • @secretthreesome : but they do apoptosis

  • neoplasm.. neoplasm...neoooplassmmm

  • great video ! really enjoyed it... Can you tell me which software i cud use to create blackboard videos like these ??

  • THC (Rick Simpson's Cancer Cure Hemp Oil) achieves this wizardry by binding to protein receptors on a cancerous cell's surface. Once attached the THC induces the cell to make a fatty substance called ceramide, which prompts the cell to start devouring itself. "We see programmed cell death" Velasco says. What's more, noncancerous cells don't make ceramide when they come into contact with THC. The healthy cells don't die.

  • the whole cancer industry is the most herendous fraud ever portrayed. Dr ralph moss was fired from slaon kettering in 1977 foe exposing sk for lying about laetrile.one out of many points. life today is little more than life in an open pit mind control experiment. to those of you who rolls your eyes prove me wrong or admit your cowardice.

  • you are so kind !

  • How rare is cancer i mean wouldn't cancer happen more often?

    and thank you so much for putting this video up!

  • how do you prevent testicular cancer

  • @Theroguesunit6 if you find the answer, let me know.

  • @Theroguesunit6 u cant

  • @Theroguesunit6

    Castration.

  • @Theroguesunit6 one in three male develops testicular cancer in the sense that they will get tumor. But they are not deadly. Most people die with testicular tumor, but not from it. So don't worry too much about it.

  • @hunterbender thanks doctor. i'll just ignore the next lump i find on my balls and not worry about it...

  • Wow! I like learning stuff just to know it. If u could make more videos like this ( and the brain teasers I love those) I like learning stuff even though I don't need to know it especially about the Human body and space. Thanks for the awesome an easy to understand video

  • Cured: A Cannabis Story (A film by David Triplett) My story

  • @kei1010101010 contact inhibition

  • I am not a medicine student, but I live in a family of MDs, so I know a think or two about cancers. This is an absolutely wonderful presentation for a layperson. Keep it up.

  • i new it was a crazy thing to try and cure... but now im thinking its just not possible.

    so what exactly are these charitys etc like cancer research UK and stuff actually doing? working there way through each cell type or what?

  • that was great!! thnx

  • im afraid to watch this video so im skipping it

  • Good Stufff... YORK EXAM HERE I COME!

  • wow, without a doubt the best video i have seen yet.

    i wish you were my teacher!

    really easy to understand, yet you still conveyed everything i needed to know!

    thanks! :D

  • Congratulations!! You have a  fantastic way of transmiting knowledge, simple and easy, perfect technic.!

  • excellent video keep up the great work

  • cellular cycopath :DDDD looll

  • who is the guy narrating?? hes awesome!! :D

  • @xGIAKANAx Salman Khan, he's on the frobes magazine's names to know.

  • Cancer and viral celsl both use teh single cel lhelicase, t oavoid Telomere abrasion stopping division

  • I honestly could have never seen my self getting into Biology, but with an academy as excellent as the Kahn Academy, and a teacher as brilliant as Sal, I couldnt help but resist. My goal is to just watch everything!

  • /agree i study biology but am now watching the videos because i couldnt help myself to watch all of the economic ones...

  • Alhamdulilah. You have a great base of knowledge.

    I wish you were my teacher, I'd probably be more interested to go to school, hehe. But I love Khan Academy, it's helped me more than a porcupine with quills.

  • Proven in laboratory dishes but not willing to test on humans or animals!

    A purified and concentrated form is RICK SIMPSON'S CANCER CURE HEMP OIL!!

  • xD just like learning from school

  • If I believed in Angels, you'd definitely be one Khan. lol Your videos are amazing!

  • No copy is perfect by the way. We science educators must steer clear of saying "perfect".

  • Funny how i also have the same problem saying Metastasis...

  • Very Simple Yet Very Helpful ... Beautiful

  • Very interesting.

    I enjoyed watching this, you're a really good teacher.
