Another early and unusual sign of lung cancer is the development of a suite of symptoms caused by paraneoplastic syndromes. These conditions appear when the lung cancer tumor puts out proteins that damage other parts of the body.
Paraneoplastic syndromes are associated with small cell lung cancer, but they can be associated with other types as well. There are multiple forms of this syndrome, based on how the tumor is impacting the body and the organs involved:
- Syndrome of inappropriate antidiuretic hormone(SIADH)
- Cushing syndrome
- Lambert-Eaton syndrome
- Paraneoplastic cerebellar degeneration
- Hypercalcemia
