Answer
The phenomenon that inhibits the formation of tumours in the human body is contact inhibition. In many animal cells, cell division usually stops when the cells come in contact with neighbouring cells. This controls cell division and prevents the cells from growing uncontrollably. Cancer cells lose this control and keep dividing, leading to the formation of tumours.
Plant cells do not show contact inhibition because of their rigid cell walls and follow a different pattern of growth. Plants may develop localised tumour-like growths, but these do not spread through the plant body like malignant tumours in animals.
