How do malignant tumors differ from benign tumors?

Benign tumors and malignant tumors exhibit distinct characteristics, particularly concerning their cellular features and behavior. The correct statement elaborates that benign tumors typically display normal cellular features and organization. In contrast, malignant tumors show abnormal cellular structures and characteristics, which can include irregular shapes, atypical sizes, and an increased rate of proliferation.

The distinctions between the two types of tumors are crucial for diagnosing and determining treatment strategies. Benign tumors generally grow slowly, do not invade surrounding tissues, and are less likely to metastasize (spread to other parts of the body). In contrast, malignant tumors may invade nearby tissues, metastasize, and possess atypical cell features that elevate their aggressiveness.

Understanding these differences underscores the importance of accurately identifying tumor types, as it directly influences patient care and potential interventions. This knowledge is fundamental in the fields of genetics and genomics in nursing practice, where assessing tumor characteristics can significantly impact patient outcomes.
