My treatment path was a lumpectomy followed by further surgery to achieve clear margins. After the surgery, I saw a medical oncologist who prescribed chemotherapy, and a radiation oncologist for radiation therapy. The breast surgeon was the one who decided whether further surgery was needed. And you're right—they work together and consult with each other as a multidisciplinary team. I was well guided through the whole treatment and didn’t worry much because I trusted the medical team and their expertise. They had experience in treating breast cancer, but for me, everything was so new and unknown. Take care
