Whether you need chemotherapy in addition to radiation depends on your specific breast cancer situation. These treatments serve different purposes and are often used together as part of a comprehensive treatment plan.
Chemotherapy circulates throughout your entire body to kill cancer cells or prevent them from growing, while radiation therapy targets specific areas where cancer cells might remain after surgery. Your oncologist will determine if you need one or both treatments based on factors like:
- The size and location of your tumor
- Whether cancer has spread to lymph nodes
- The timing of your treatments (before or after surgery)
- Results from specialized tests like Oncotype DX that help show who will benefit most from chemotherapy
Many breast cancer patients receive both treatments, but thanks to advanced testing methods, some individuals can now avoid chemotherapy if it's unlikely to benefit them while still receiving radiation as part of their treatment plan.
