A cancer-free surgical margin is often a sign that all the cancer was removed. In this
case, observation is recommended. However, the chance of remaining cancer cells is
higher for some stage IB cancers. In these cases, chemotherapy may be received.
When cancer is found in the surgical margins, a second surgery is the preferred
treatment. Radiation therapy is another option. If you have stage IB cancer,
chemotherapy may be added to surgery or radiation therapy.
If you are unable or refuse to have surgery, you may be treated with radiation therapy.
The goal of radiation therapy for stage I is to cure the cancer. You may receive
conventional radiation therapy. Conventional radiation therapy gives radiation in small
doses for weeks and targets both the tumor and some normal tissue. One example is
3D-CRT. A newer type of radiation therapy—SABR—is also recommended.
