Cancer is ultimately the result of cells that hysterically grow and do not die. Cells can experience uncontrolled growth if there are mutations to DNA, and therefore, alterations to the genes involved in cell division. Cancer occurs when a cell's gene mutations make the cell unable to correct DNA damage and is unable to destroy itself. There are over 100 different types of cancer each classified by the type of initially affected cell. Isoniazid, a well-known antitubercular agent has been reported to exhibit some cytotoxic activity...
