Feedback:
Metastasis is one of cancer's most discouraging characteristics because even one malignant cell can give rise to a metastatic lesion in a distant part of the body. Not all cancerous tumors are large in size. Carcinogenesis is the process of malignant transformation, and it is not a characteristic of cancer. Cancer grows rapidly, not slowly.
