Skin Cancer/DNA damage/ Cell division Question?

Post by rosarioduniam89 » Sun Jan 11, 2009 11:45 pm

- Scientists believe that some cancers are hereditary. One form of cancer is caused by ultraviolet radiation such as the type produced by the sun. It causes damage to the DNA that controls cell division. Disabling the control mechanisms for mitosis can result in various forms of skin cancer. Could this type of cancer be passed on to one's offspring? Explain with specific reference to mitosis and meiosis.


rough answer I have;

Cancer comes from mutations within the cells that negate inhibitors and cause the cells to reproduce uncontrollably resulting in a tumor or growth. The UV rays you are referring to actually cause the mutations themselves and therefore this type of cancer would not be passed down through hereditary means.

I need something more solid, help please?

Briefly: UV induced skin cancer itself does not get passed on to the offsprings, because the mutations that lead to cancer are located in the skin cells, not in germ line cells.
