what is the difference between a benign and a malignant tumor?
Compare difference between benign and malignant tumors. 1) Benign: Grow slowly/ Well-defined capsule/ Well-differentiated/ Low mitotic index/ Does not metastasize. 2) Malignant: Grow rapidly/ Not encapsulated/ Poorly differentiated/ high mitotic index/ Metastasis. î î î.
One of the most important factors in classifying a tumor as benign or malignant is its invasive potential. If a tumor lacks the ability to invade adjacent tissues or spread to distant sites by metastasizing then it is benign, whereas invasive or metastatic tumours are malignant.
