A malignant tumor is considered cancerous because it has the ability to invade surrounding tissues and spread to other parts of the body, which is a defining characteristic of cancer. Unlike benign tumors, which remain localized and do not invade nearby tissues, malignant tumors can grow uncontrollably and may metastasize, leading to further complications and making them significantly more dangerous. Understanding the nature of malignant tumors is crucial in the field of health and medicine, as they necessitate different treatment approaches compared to benign tumors, which can often be managed with observation and are less likely to pose serious health risks. This distinction highlights the importance of accurate diagnosis and treatment planning in oncology.
