What term is used to indicate the presence of cancer cells?

The term "malignant" is used to indicate the presence of cancer cells. Malignant tumors are characterized by their ability to invade surrounding tissues and spread to other parts of the body. This invasive behavior is a hallmark of cancer and is what distinguishes malignant tumors from benign ones, which do not invade nearby tissues or spread. The presence of malignant cells typically indicates the existence of cancer and necessitates medical intervention. Understanding this distinction is crucial for medical assistants, as it helps them recognize the seriousness of a diagnosis and the potential treatment options that may need to be considered for patients diagnosed with cancer.
