Cells are the basic units of living organisms, usually when cells become too old or when they get damaged they die, and new cells start growing and dividing and take their place. It begins when genetic changes take place, and normal cells start growing in an uncontrolled manner, and form a mass of cells which is called tumour.
There are Benign tumours and Malignant tumours. Benign tumours are non cancerous tumours which do not spread, moles in our body are benign tumours, whereas Malignant tumours are cancerous, they grow and spread.
Cancer is divided into 4 types based on its origin, so there are four main types of cancer:
1) Carcinomas and their examples include prostrate, breast, lung cancer, etc.
