Important Safety Information:
Radiosurgery may cause side effects that can vary depending on the part of the body being treated. The most frequent ones are typically temporary and may include, but are not limited to, fatigue, nausea, skin irritation, and hair loss. Treatment sessions may vary in complexity and time. Radiosurgery is not appropriate for all brain tumors. Cancer patients should discuss the potential for side effects and their severity as well as the benefits of radiosurgery with their doctors to determine if radiosurgery treatments are right for them.
