Metastasis refers to the spread of cancer cells from the original site to distant parts of the body. It is a characteristic feature of malignant or cancerous cells, which can invade neighboring tissues and spread through the bloodstream or lymphatic system to form new tumors in other parts of the body. Option A is incorrect as helper T cells are not directly related to cancer cell invasion. Option B is incorrect as mutation is a normal process in the development of cells, but it does not necessarily lead to metastasis. Option D is incorrect as infiltration refers to the initial invasion of cancer cells into adjacent tissues, which is only the first step in the process of metastasis.
