How does cancer get inherited...in cell level?

Postby Chiabete » Fri Nov 02, 2012 12:04 pm

Hey,

Firstly, forgive me for my probably indecent English.

I was reading about how cancer evolves in a cell and that cancer can become inherited. I need a little brainstroming here so I can understand how this actually happens. So the germline cells that produce sex cells ( ? ) gets the effects of carcinogens/radiation causing there to be mutations in them..so what actually happens that the effect of the mutation gets inherited? In a human. So human A gets radiation in her ovaries? Causing the germline cells to start producing mutated sex cells? But aren't the eggs already been "evolved to the finest" when human A was just a thing in her mothers belly?

I'm so confused and not sure where I went wrong.


>.< I feel like I am doing a terrible job trying to explain what I need to know..but I hope someone gets what I'm trying to ask ><

Cell level is a wrong word to use....gene level is more better.

First, there is difference between cancer and mutation (which may lead to cancer).

What you probably mean, is that the DNA in egg/sperm changes after some treatment (chemical, irradiation) and this mutation is transferred to offspring.

Cis or trans? That's what matters.

Yes, well if you say it like that it makes more sense. So there's an egg/sperm cell and in it happens a mutation that leads to cancer..and it gets inherited..so if this persons has a child it will have a mutation in the DNA and the child might get cancer from that, and the childs child aswell.

Ok, so if this is the case, thank you for clarifying!
