Hormones are peptide or a steroid which is produced by a tissue and conveyed to the bloodstream to the target organs for maturation<br /> Hormones are involved in growth and development of an individual <br />
HORMONE DEPENDENT CANCERS:<br /> Hormones share a strong bond in cancer and its progression and the role in which hormones play in cancer are seen in breast ,prostate and ovaries<br />
ANTI ANDROGENS :Bicalutamide and Nilutamide which block the binding of androgen to receptors are commonly used as a hormonal therapy <br />GNRH AGONIST :Leuprolide acetate or Goserelin acetate can be given which eventually leads to chemical castration <br />
<ul><li>Testosterone hormone stimulates the growth of cancerous cells and it is the fuel for cancerous growth
Luteinising hormone from the anterior pituitary stimulates the release of testosterone from the testes and hormonal therapy in prostate cancer is androgen deprivation which can be accomplished surgically by orchidectomy (castration ) as the body's source of testosterone is removed </li></li></ul><li>
Conclusion <br /> Breast and Prostate tumours have a common feature in that at some stage in their evolution they were hormone dependent cancers, and therefore hormone therapy is an intuitively obvious therapeutic approach<br />
