Tumour

A tumour is a lump or growth of tissue which is made up of abnormal cells. This word is often used for a liquid filled growth called cyst and for a solid growth called neoplasm which can be cancerous or non- cancerous, i.e. benign or malignant.

Benign tumours

Benign tumours are non-cancerous growths which grow slowly and do not spread to other tissues. They are not life threatening and most of the benign growth does not cause any problem. But some of the growths can cause problems when they increase in size and start putting pressure in the surrounding areas. Moreover, if benign tumour occurs from the cells in hormone glands then, that can cause severe health problems because of excessive production of hormones.

Malignant tumours

Malignant tumours are cancerous growths which tend to grow very quickly and invade into nearby tissues and organs, which can cause severe damage. Some malignant cells may enter into small blood vessels and spread to other parts of the body through bloodstream and start multiplying there to form secondary tumours.
