Question

Which kind of tumor grows slowly and is surrounded by membranes that prevent it from spreading from the original site?
a. benign
b. metastasisc. malignant

Answer 1

The answer is benign this is because a benign tumor is the only tumor that can not spread making it non cancerous. The other two words have to do with cancerous tumors.  Metastasis is a secondary caner growth which means where the cancer spread. Malignant is an original tumor that is cancerous which means it is able to spread
