What is Cancer?

In this video Paul Andersen answers the very simple question: What is cancer? He explains how damage to the DNA can create uncontrolled cell growth. He explains how malignant tumors can spread the disease throughout the body and gives possible treatments.

Thanks for describing cancer so easily for what my professor took 2 hours online and still failed. Thanks for such a great and smooth informational video.

[irvingcm]

Thank you for that most lucid explanaition

[kalewakalahiki]

I like how he says very simple and then give a 6 minute explanation on what cancer is

Why can't the macrophages and killercells in the immune system kill this tumor? Please like so Bozeman can see this.

Youre so awesome! I love how well you explain things. I will definitely pass my classes thanks to you! :)

Wish you went more into anchorage and density dependent inhibition because that's how it's characterized in AP Biology. But great video they're all so helpful!

[lulubaniqued]

Very informative for a regular person like me! Thank you for doing this video!

[kevinhartzog]

You do much too good a job with these videos! Length is just right, the content is very focused, the excellent examples.

Yes it was helpful. I was recently informed of a large tumor that must be removed, and I will learn if it is cancerous in a few days. Therefore, this short informative video was a great refresher tool to remind me of the cause of tumors. Thank you!

Well done, this is a good introduction video to tumor forming cancers (About 85% of all cancers) 
We desperately need better ways to more accurately Grade and Stage cancers (Truly knowing early-on which mutations are really dangerous ones). Without good low-cost methods to measure the metastatic potential of a cancer the quality of expensive cancer studies has always been compromised.

Perhaps one of Mr Anderson students will be part of the solution one day. You have a really excellent teacher here.

[nevinroyath]

Brilliant! The video was easy to understand. Thank you kindly for the video. I found it very helpful.

[Annibals]

great video. finally understood this matter. flawless flow in speaking

[tuncalikutukcuoglu]

A fine explanation of cancer, but it focuses more on therapy than on causes and prevention. In that sense, a corporate-friendly neoclassical explanation..

im studying medicine and i watching these kind of videos

[coreyzerphey]

Yes this was very helpful, still 6 years later :)
