Eligibility Criteria:
Inclusion Criteria:~* Ability to understand and the willingness to sign a written informed consent document~* Pathologically confirmed limited stage (LS)-SCLC or extensive stage (ES)-SCLC~  * LS-SCLC - stage I-III (Tany, Nany, M0) that can be safely treated with radiation doses.

- Minimum Age: 22 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Prevention (TTFields therapy, questionnaire) (Type: EXPERIMENTAL): Patients undergo TTFields therapy over 18-24 hours daily. Cycles repeat every 4 weeks for 12 months in the absence of disease progression or unacceptable toxicity.
