What is the difference between a benign and malignant tumor?
Answer
A benign tumor is slow growing and is encapsulated within the cell wall. It is well-differentiated from the healthy tissues surrounding it. It is non-ulcerated and non-metastatic. It is not extended or fixed into surrounding tissues. It can become malignant so it needs to be monitered. Problems exist when it needs to be surgically removed and healthy tissue is destroyed in the process.
A malignant tumors is grows rapidly with very fast cell division. It is ulcerated and very poorly differentiated from the surrounding tissue. It fixes itself to healthy tissue mixing in with regular cells eventually destroying them. They can be metastatic and spread to other areas of the body via the lymphatic system.
