Question:

What is the reasons for cancer?

Answer:

​ The staple reason for cancer is the rapid cell division. When the cell division of a particular place grows  non-stoppable then cancer occurs in that organ. The first symptom of cancer is cyst. But it doesn't mean that all the cyst cell or tumor cell should be cancer cell.

The main difference between a cancer cell and a tumor cell is that, the growth  of a tumor cell is stoppable but the growth of a cancer cell never can be stopped.

It should be noted that, as per the recent scientific report an woman had died long ago due to uterine cancer and during her postmortem her cancer cell was preserved and still that cell is growing and it was kept in a warm ventilation with all the life-sustaining components.
