Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.

Malignancy (from Latin male 'badly' and -gnus 'born') is the tendency of a medical condition to become progressively worse; the term is most familiar as a characterization of cancer.

Like methadone, Suboxone blocks both the effects of heroin withdrawal and an addict’s craving and, if used properly, does it without causing intoxication.
