Malignant tumors tend to have
-
Irregular borders.
-
Smooth borders.
-
Regular borders.
-
Nonexistent borders.
Correct Answer
A. Irregular borders.Explanation
Malignant tumors tend to have irregular borders because they are characterized by uncontrolled growth and invasion into surrounding tissues. Unlike benign tumors, which typically have smooth and well-defined borders, malignant tumors often invade and infiltrate nearby tissues, causing irregular and jagged borders. This is due to the aggressive nature of malignant tumors, which can spread and metastasize to other parts of the body. The irregular borders of malignant tumors are an important characteristic that can be observed through imaging techniques and used to differentiate them from benign tumors.Rate this question:
