Why can a HeLa cell survive with such an abnormal karyotype?

Why do you think a cell line such as HeLa could survive with a grossly abnormal karyotype whereas an embryo can not?

I understand that HeLa cells are cancerous but I am not sure how to approach this question.

Any help is appreciated =)

Update:

I know that cancer cells are immortal lol I'm just wondering how the karyotype comes into effect.

    Cancer cells are immortal. Thats why it is so hard to defeat cancer. The stuff that kills cancer usually kills tons of healthy cells before even starting to kill the cancerous ones. The cells can divide as many times as they want.
