Site-Specific Factor 1

Separate Tumor Nodules - Ipsilateral Lung

Notes

**Note 1:** Information about separate tumor nodules in the ipsilateral lung (same lung) are collected in T as an element in anatomic staging. It is also collected in this field as it may have an independent effect on prognosis. See distant metastasis for separate tumor nodules in the contralateral lung. **Note 2:** Separate tumor nodules can be defined clinically (by imaging) and/or pathologically. **Note 3:** If separate tumor nodules are not mentioned in imaging and/or pathologic reports, use code 000. **Note 4:** For in situ tumors, code Site-Specific Factor 1 to 000.
