My understanding of cancer is that an organ’s cells tgo rogue. It starts to multiply uncontrollably and this affects certain functions of that organ. Moreover, this behaviour spreads to other organs resulting in uncontrollable cell multiplication of that organ and so on.
What I don’t understand is how does the uncontrolled cell multiplication of one organ “spread” to another wherein that impacted organ also begins to show this behaviour? How can say breast cells impact lungs by spreading to them considering they are both different organs, functions, cells.
In: Biology
Cells have molecules on them that make them stick together which is why you don’t fall apart into a blob of mush. These molecules are produced by genes in a cell. Cancer cells turn these genes off, so cancer cells no longer have these molecules. Which means that they stop sticking to other cells and can start moving around. So that cell, when it divides, can migrate directly onto another organ or slip into your blood or lymph and get carried down the river (so to speak) until it falls out like silt. Cancer cells from a body all originate from the same cell (unless you have more than one cancer which is rarer)
