What is the grading of malignant tumors based on?

What is the grading of malignant tumors based on?

Degree of activity: Tumors are graded depending on how much replication they have the potential of, so if a tumor is very active with a lot of evidence of dividing cells - that is grade 3, so worse the prognosis as spreads faster and gets more resistant to chemo drugs. ...Read more

How do tumors develop from being benign to malignant?

How do tumors develop from being benign to malignant?

Additional oncogenes: Many tumors begin as benign, eventually transforming to malignancy. Small lipomas as they grow develop additional oncogene mutations to become liposarcomas. Adenomatous polyps that are benign can have Cmyc and p53 nutations leading to malignant polyps. Additionally telometrase activity has to be put in place for immortality probably thru EBV transfection. ...Read more
