There is no one definition that describes all cancers. They are a large family of diseases which form a subset of neoplasms, which show some features that suggest of malignancy.
A neoplasm or tumor is a group of cells that have undergone unregulated
growth, and will often form a mass or lump, but may be distributed
diffusely.[7][8]
Six characteristics of malignancies have been proposed: sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis.[9] The progression from normal cells to cells that can form a discernible mass to outright cancer involves multiple steps
