Which statements are true regarding neoplasms?

Neoplasms, particularly malignant ones, are characterized by their ability to grow by infiltration, which means they invade surrounding tissues and disrupt their structure and function. This infiltrative growth pattern is a hallmark of cancerous tumors, leading to tissue damage and often complicating treatment and recovery. This invasive nature distinguishes malignant neoplasms from benign ones, which typically grow by expansion and do not invade nearby tissues.

In contrast, some other options suggest features that either do not apply universally to neoplasms or specifically to benign tumors. Specifically, certain neoplasms may resemble the tissue of origin, but they can exhibit a range of growth behaviors depending on their nature—malignant tumors generally do not resemble normal tissue as closely as benign ones. Additionally, the statement about consistent slow growth and always being benign is not accurate since malignant neoplasms can also exhibit rapid growth and aggressive behavior.

Thus, the understanding that neoplasms can damage surrounding tissues through infiltrative growth is essential when studying their implications and behavior in the body.
