Have you ever talked about mitosis, in biology class?
Mitosis what we call the process in which our cells copy themselves, by dividing.
And through this, more and more copies of cells are made.
Now, our cells usually know when to stop dividing.
There's something in biology called the "density-dependent inhibition of growth."
In other words, our cells only create as many more copies as our bodies need.
But a cancerous cell is different, because it doesn't know when to stop dividing. It just keeps on dividing, and dividing.
And what's more is that it divides really fast. Cancerous cells divide uncontrollably, and much more quickly than normal cells.
Cancer is basically a malfunction in mitosis.
It's where cell division has basically gone horribly wrong.
cancer cell has : 1- continous proliferation. 2- genetic mutations 3- overexpression of oncogenes. 4- invation and metastasis
