Why Heart Cancer Is So Rare It (Almost) Never Happens

- The heart is practically immune to getting cancer. 2 in 100,000 of those who have cancer are those with a primary cancer of the heart. That is an astonishing low number. So, what is so special about the heart that it rarely, if ever, gets a primary cancer? The answer is linked to how the heart cells can divide and repair themselves.

Just imagine if our schools adopt these kind of videos for teaching instead of those cheap books with poor sketches for illustrations
Now imagine those same schools with cheap books having the budget to buy and maintain proper AV equipment.
Who says thats schools is for learn, it just for instruct you make things
I’ve always wondered about this! Thanks for sharing this important fact!
Glad it was helpful!
Again, great job. Way to put out information in a very logical and thought provoking manner. You guys always post great content. Thank you very much!
Our pleasure! :)
Very interesting!!
Very well done.

Anand now you just jinxed us, thanks!
This video made me feel really bad, even though I live mostly a healthy lifestyle. 😣

Good video, this is edutainment
Guys and girls, if you're an anime fan, you can watch Cells at Work Season 1, Season 2 and Cells at Work Code Black, to understand more better of human body
I recommend these anime
You're basing your argument about the rarity of cancer of the heart on the fact that cardiac myocytes are terminally differentiated type of cells that rarely divide if ever and also they're not oftenly exposed to carcinogens. If your point is correct, then why do neurons get cancer way more often than cardiac myocytes although they share these same properties, and actually the brain is even more protected from carcinogenes by the blood brain barrier?
Great question!
Similar to cardiomyocytes, neurons actually don't becomes cancerous often either. Cancers of the brain occur because of other brain cells such as glial cells (gliomas), outer covering of the brain (meningiomas) or the blood vessels in the brain. Glial cells divide and replicate throughout your life, interact with the blood brain barrier, and are involved in generally taking care of your brain. Also, 70-80% of the heart is made of cardiomyocytes, while neurons are about 50% (or even less according to some estimates) of the brain, rest being glial cells. So, if you consider the whole organ (every cell type), heart cancer is less likely to happen than brain cancer.
Take a look at these two sources:
seer.cancer.gov/statfacts/html/soft.html (freq. of heart cancer in USA)
seer.cancer.gov/statfacts/html/brain.html (freq. of brain cancer in USA)
