29-year-old mother diagnosed with stage 4 oesophagus junction cancer after initial heartburn

A 29-year-old mother from Pimpama has been diagnosed with stage 4 oesophagus junction cancer after initially dismissing persistent heartburn and reflux as minor digestive problems.

Jemma Lunson began experiencing reflux and heartburn earlier this year and treated the symptoms with over-the-counter medications. By April she developed difficulty swallowing, with food and eventually liquids catching in her throat. An endoscopy identified a 4-centimetre tumour at the junction of the oesophagus and stomach about 38cm down, and biopsies confirmed cancer. Subsequent scans showed the disease had spread to her liver, the right hip bones and several lymph nodes.

"She just thought it was maybe her diet or something to that effect, but it didn't get better," said her sister, Maddyson Solano, describing how ordinary symptoms delayed suspicion. Solano said Lunson had begun to gag and choke when swallowing and at times had to manually dislodge food. "That's when she went to her doctor and said something's not right," Solano said.

Doctors told the family the diagnosis was rare for a woman of Lunson's age; oesophageal and gastroesophageal junction cancers are more commonly diagnosed in older men with a history of smoking or heavy alcohol use. Clinicians warn those cancers are often aggressive and discovered late because early symptoms—persistent reflux, heartburn or indigestion—mimic common, benign digestive problems.

Medical teams have fitted Lunson with a port and planned a regimen of chemotherapy and immunotherapy to begin in coming weeks. Treatments will be administered at the hospital every two weeks, supplemented by at-home infusions, according to her family. Lunson has stepped back from work to focus on treatment and caring for her 3-year-old daughter, Sunni; she currently relies on pureed and liquid foods because of swallowing difficulties.

Family members described a swift emotional adjustment since the diagnosis. Lunson's long-time partner, Ethan Murdoch, who has known her since childhood and has been in a relationship with her for four years, is supporting her through appointments and day-to-day needs. Friends and relatives have been providing meals, transport and childcare. The family has also established a fundraiser to help cover medical bills, rent and to provide financial stability for Sunni.

"Her initial thought was, I have a three-year-old child. That was her biggest thing—what about my child and what about her future?" Solano said. She said the family hopes Lunson's story will encourage others to seek medical review for ongoing digestive symptoms. "Everyone has heartburn at some point, so you don't think to get it checked. But if it's ongoing, you must."

Clinicians say symptoms that warrant medical assessment include persistent reflux or heartburn, difficulty swallowing food or liquids, food getting stuck in the throat, unexplained weight loss and chest discomfort or choking while eating. Because swallowing problems commonly appear at later stages, physicians emphasize that prompt evaluation of persistent or progressive symptoms increases the chance of earlier diagnosis, when treatment options may be broader.

Lunson's family described her as a devoted, family-focused mother who fills weekends with simple activities—morning coffee, park visits and trips to the beach. They said the diagnosis has been devastating but that they are trying to manage emotionally while organizing practical support for treatment and for Sunni.

As Lunson prepares for systemic therapy, her relatives and friends continue to share updates on her condition and to urge others to take persistent digestive symptoms seriously. The family said they will focus on maintaining Lunson's quality of life and ensuring her daughter has support in the months ahead.
