Paraneoplastic Syndromes is a group of symptoms related to a rare form of Lung Cancer and are not fully understood.

Some neoplasms have the ability to secrete hormones or other proteins that results in changes in symptoms .

Symptoms may be related to Endocrine Disorders

This can occur in up to 20% of lung cancers

Importantly this can cause changes in:

1.)  Emotions

2.)  Physical nature

3.)  or other aspects of the person

It does not necessarily mean that metastases have occurred.

It differs from having a neoplasm in the affected area that these hormones are typically released.

Some examples would be:

  • Inappropriate antidiuretic hormone
  • Abnormal increase of calcium
  • ACTH or Adrenocorticotropic hormone
