Breast Cancer Doctor's Own Diagnosis Transforms Her Patient Care and Purpose

Sue Hwang was running on fumes. A radiation oncologist specializing in breast cancer, a single mother of three boys in three different schools on three different baseball teams, three dogs at home, and a practice so busy she was planning her retirement party. In January 2024, her best friend Devina McCray, a breast surgeon, essentially dragged her to get a mammogram she kept postponing. Hwang was 46 and felt invincible. She had no family history. She was healthy. The mammogram could wait until summer.

It couldn't. On January 25, the radiologist found calcifications—nothing alarming, she thought. Stage zero, easily handled. Then came the ultrasound. Five masses. Not calcifications. Five distinct tumors hiding in her breast tissue, invisible to touch, the kind doctors call sneaky. A biopsy confirmed what she already knew would be bad: Stage 2 invasive lobular carcinoma. Hwang had spent her career explaining this diagnosis to other women. Now she was the patient, and the terror was real.

The hardest conversation wasn't with her oncologist. It was with her sons. James, her oldest at 15, immediately shifted into problem-solving mode—how would they treat it, what was the plan? Sam, 13, went quiet and started doing his math homework on his phone. Nathan, 11, asked if death was dark. A year earlier, the mother of one of James's close friends had died of breast cancer. Hwang had to tell her son he had the same diagnosis and somehow convince him it would be different. She scheduled her double mastectomy within days of the diagnosis.

When surgeons opened her breast during the operation, they stopped counting tumors after ten. She endured four cycles of chemotherapy over two months, working through most of it. Her friend Tracy Kelly flew down and slept beside her in bed during recovery, managing her own family and her own radiation oncology practice back home. Hwang returned to work after just two weeks, wearing scrub caps to hide the bald spot that appeared two and a half weeks into chemo. She had planned to keep her diagnosis private, to slip back into her life as though nothing had changed. Her hair had other ideas.

Once patients could see she was sick, she stopped hiding. She told them the truth: she had just had mastectomies. She had survived chemotherapy. They could too. The effect was immediate and profound. Women who had come in terrified, resistant to surgery, suddenly let their guard down. They asked personal questions. They trusted her differently. There was a bond that hadn't existed before—a shared understanding that she wasn't speaking from theory anymore. She was speaking from the operating table.

In July 2024, she underwent a hysterectomy and oophorectomy. Lobular cancers feed on hormones, and she chose to eliminate the source rather than manage it with injections. She started endocrine therapy and a CDK4/6 inhibitor. The physical treatments ended, but something else began. During her December break from work—a month away from breast cancer, from patients carrying the same fear she carried—she read the messages flooding her social media. Women told her they felt abandoned after treatment ended. The protocols stopped. The appointments thinned. The fear didn't.

She came back to work with a new purpose. She had written a book about her journey, released in January 2026, and she was now focused on survivorship—on guiding women through the years after treatment when the real psychological work begins. Her sons were now 17, 15, and 13. The fighting between them that used to drive her crazy now felt like a gift. She had become a better doctor because she had become a patient. Her recommendations were no longer vague platitudes about diet and exercise. They were specific, tested, lived. She meditated. She lifted weights. She protected her sleep. She was still standing, and she wanted other women to know they could stand too.
