Cancer (malignancy is synonymous) refers to neoplasms with malignant potential, i.e. for local invasion and metastasis. This article is a list of different cancers or relevant tumor classification systems, although noting that not all tumors are cancerous. For a list of cancer staging systems, see the separate article.

Cancer is often used synonymously with carcinoma, but this is erroneous as whilst all carcinomas are certainly cancers, many cancers are not carcinomas, e.g. lymphomas and sarcomas.

Neoplasms and tumors can be benign or malignant, and therefore should not be used as synonyms for cancer.
