Metastasis will happen and cancer cells invade nearby healthy cells, tissues, lymph nodes, organs or will migrate to distant organs.
The two different types of stem cells broadly classified as are Embryonic stem cells and adult stem cells. Embryonic stem cells are obtained from the blastocyst layer of the embryo and are pleuripotent. Whereas adult stem cells are the undifferentiated cells from tissues of an adult or a child. They can be unipotent or multipotent.
Explanation:
Cancer cells migrate to other parts of the body via blood and lymphatic system. This is called as metastasis. Cancer cells when becomes tumour they develop their own blood vessels and obtain nutrients from them. Once the tumour gets big it pushes the normal healthy cells of the neighbouring tissues and keeps on spreading.
Stem cells obtained from the embryo can differentiate into any types of cell and when grown in-vitro can dramatically form the three germ layers.
The adult embryo cells are found in less quantity, their role is to repair the tissue they reside in.

In general terms, “sex” refers to the biological differences between males and females, such as the genitalia and genetic differences. “Gender” is more difficult to define, but it can refer to the role of a male or female in society, known as a gender role, or an individual's concept of themselves, or gender identity.
