This is a really nice question related to the nature of how cancer forms.
00:04
And it all is about dna and the transformation of the cell from a regular cell to a cancer cell.
00:11
So this is caused by mutagens and mutagens can cause mutation and they can be carcinogens, right? just because you mutate your dna doesn't mean it's going to immediately cause cancer.
00:21
But some mutagens are carcinogens.
00:24
And these include things like radiation, chemicals, and viruses.
00:27
This creates dna damage, which things like cross -linked bases, oxidation of the base itself, and double -stranded brakes.
00:39
Also, single -srended brakes that need to be fixed.
00:42
Normally, your body's really good at fixing the mutations or having programmed cell death if it gets too bad.
00:50
Also, a lot of these mutations, like i said, don't really do anything significant, and the cell's totally fine.
00:55
Sometimes, however, these different metagens can cause increases in cell growth and increase in cell movement, which are hallmarks of cancer cells that can go out of control.
01:07
So to answer your question, heredity is obviously going to be one way you can get cancer because you might inherit a bunch of mutations from your parents of things like that.
01:22
The environment obviously is a factor here, radiation, chemicals you're exposed to, definitely one factor that causes cancer.
01:31
Viruses can cause cancer.
01:33
So there's a specific connection between things like, for example, the human papilloma virus and hepatitis.
01:41
Replication errors can cause us as well.
01:43
There could be absolutely no problems here, but you could still get cross -length dna, problematic bases, incorrect mutations that can cause these things...
