Tumours can develop anywhere on the surface or in the interior of the body. Not all tumours are however, cancerous. Two general types of tumours are recognised:
1. Benign or non malignant and
2. Cancerous or malignant.
1. Benign or non malignant and
2. Cancerous or malignant.
Benign or Non malignant Tumour vs Cancerous or Malignant tumour
| Benign or Non malignant Tumour | Cancerous or Malignant tumour |
| It is enclosed in the connective tissue. | It is not enclosed in any specific tissue. |
| It remains confined to the site of its origin. | It is not confined to the tissues. |
| It may grow in size but does not spread to other parts of the body. | The cancerous cells are carried by blood or lymph to other parts of the body where they spread secondary cancers or metastasis. |
| Growth of tumour may cause some pain if it is processed against some vital organ or tissue. A benign tumour may turn malignant and due to his reason it is removed as soon as it is noticed. | As the cancerous cells grow rapidly, they destroy other normal cells. The spread tumours is invariably very fatal. |
