I never paid attention to these videos in school, now here I am 7 years later watching them out of interest 😂

Mom died of Stage 4 SMALL CELL CARCINOMA LUNG CANCER on 10/9/11.  This doc explains SO much 2 me. I just followed docs orders, showed love and support & prayed.  Thanks this REALLY HELPED! RIP to my beautiful mom.

My dearest uncle just died because of cancer last month..... It made me curious about cancer and how it works. Then I found this video. It's very informative and great. Thanks for this video and to the researches who studied and continues to study about it. I hope we find a cure soon so that ppl won't die because of this disease anymore. Losing my uncle really killed me on the inside

While this video is a great start to understand the basic mechanisms behind cancer, it should be noted that cancer research has progressed significantly since this video was published. For example, cancer does not always have to be linked to mutations in genetic material aka changes in DNA. Cancer can emerge through various developmental biological processes, such as through epigenetic changes, which involve changes to chemical attachments to DNA. These changes affect gene expression without changing the underlying DNA sequence.

rip auntie Olie.She fought hard but unfortunately fell to cancer today...

God bless those poor people and children in hospitals dying day by day in hospitals because of stupid cancer!

I have the highest respect and admiration for people doing this research.

I lost my cousin four days ago to cancer 😢kindly say a prayer for for him when you come across this 🙏

Wow, who else is watching in 2026?
This is very explanatory. Thank you very much

Thanks YouTube! I understand it,I would say 10 minutes YouTube vedio is important than 16 years school books

My mum lost her battle with small cell lung cancer on 4th Feb 2021, she was diagnosed early January 2021, it took one month to take her away from us, one month to shatter our hearts into pieces. If anyone that smokes ever reads this - Quit now, it’s not worth it. I’d do anything to go back and stop my mum from smoking for the first time to maybe stop this from happening, even if it was at the cost of my own life. Such a selfless, caring and amazing person taken far too early. This planet and this life can be so evil.

Thank you. Great animation. Cancer, HIV both giving us problems in Africa

This video was absolutely fantastic. Easy to understand and straightforward. Thank you. :)

Want to be a doctor one day, so I'm watching this rn and learning about serious illnesses like these.

Am i only the one watching this in 2020 😵

It's just insane to me that a cell can just function improperly and turn into a life threatening disease. I'm actually a major hypochondriac and I constantly convince myself I have cancer and the word even freaks me out but it's so interesting to learn about.

used this for as human biology revision thank you

Thank you! This video really helped me grasp the concept quite well.

I love how he equates us to chairs.

Thank you for taking the time to make this video. My mother was diagnosed with cancer yesterday and it left me with a lot of fear, confusion and questions. This information will be helpful as we navigate this illness and treatment.
