Cancer cells are wonder cells and an Italian surgeon had discovered another amazing trait of cancer cell by using just a microscope around a decade back. Francesco Durante the surgeon had found that the cells in the most malignant cancers are very similar to the embryonic cells of the organ where the cancer begun from.

They observed that cells in human basal-like breast cancer share features with the embryonic mammary stem cells which are the progenitors of all cell types in the mammary
