Cancer cells cancer cells generally form benign tumors. have a slow mitotic rate. may exhibit metastasis. are indistinguishable from normal body cells. do not form neoplasms.

may exhibit metastasis

Cancer cells may exhibit metastasis, this is true.

Other choices are not true of cancer cells because:
Mitotic rate of cancer is high, not slow. Benign tumors are not cancer. It is distinguishable from normal body cells, it forms neoplasms. 

The answer is may exhibit metastasis. This is a pathogenic operator's spread from an underlying or essential site to an alternate or optional site inside the host's body; it is commonly talked about accordingly spread by a dangerous tumor. The recently neurotic destinations, at that point, are metastases (mets). 
Malignancy happens after cells are hereditarily adjusted to multiply quickly and uncertainly. This uncontrolled multiplication by mitosis delivers an essential heterogeneic tumor. The cells which constitute the tumor in the end experience metaplasia, trailed by dysplasia then anaplasia, bringing about a threatening phenotype. This threat considers intrusion into the flow, trailed by attack to a moment site for tumorigenesis.
