When does neoplasm occurs?

Answer 1

Neoplasm is a group of deformed cells developed from even a single normal cell in the beginning and which increases in number to form a malignant or benign tumour. The question as to when and how it occurs is still unknown; whether it could be the result of frequent consumption of certain kind(S) of food or else is still not absolutely clear, but there is a general belief that it is triggered by long term depression. It's going to be the most stunning achievement of the modern medical science if we can find out how neoplasm occurs.
