How does Lysodren work? What will it do for me?

Mitotane belongs to the group of cancer-fighting medicines known as antineoplastics. It is used to treat certain kinds of cancer that affect the adrenal cortex (the part of the body responsible for making steroid hormones like cortisol). Mitotane reduces the amount of adrenocorticoid hormones produced by the adrenal cortex and affects how steroids are broken down in the body.
