Question

A couple who are close family friends of yours are concerned that their children may have a high risk of inheriting cancer from one of them. write a paragraph that describes the steps you would take to 1) Identify if either or both of the parents may contribute to the risk of cancer. 2) explain to the parents how genes may lead to the development of cancers that are not inherited and 3) how they could identify if an embryo ham the genetic components that will lead to cancer?

Answer 1

1.If either or both the parents have cancer,then the risk for contributing in cancer is very high.This can be analyzed with the help of family tree or pedigree analysis.But,its not always that if either one or both parents have cancer than offspring will get cancer.

2.Most cancers are not inherited,most cancers are occur due to genetic changes which a person acquire during his lifetime.The mutations which occur in genes can lead to development of cancer even its not inherited.

3.Tumors may arise from embryonic cells and can be identified by biopsy.
