Which of the following is a characteristic of malignant tumors?

Malignant tumors are characterized by their ability to invade nearby tissues. This invasive nature allows malignant cells to spread through the surrounding environment, making it challenging to contain the cancer and often leading to metastasis, where cancer cells spread to distant parts of the body. Unlike benign tumors, which tend to grow slowly, remain localized, and do not invade surrounding tissues, malignant tumors exhibit aggressive growth patterns and can disrupt normal functions of the organs they invade. Their properties are directly related to their potential to cause significant health problems, including the spread of cancer throughout the body.
