A young mother tragically passed away from cancer just weeks after mistakenly believing she was pregnant.

Fiona Gallacher, a resident of Holytown in North Lanarkshire, endured severe stomach ache, bloating, and vomiting for two months.

Initially attributing her symptoms to feeling unwell, Fiona was prompted to seek medical help when a pregnancy test returned negative in January. Following a visit to A&E, test results revealed she was suffering from stage-four adenocarcinoma, an aggressive cancer affecting glandular tissues.

Test results days later revealed she was suffering with stage-four adenocarcinoma, an aggressive cancer of the glands that secrete mucus. Doctors originally gave her between six months and a year to live when Ms Gallacher was diagnosed in January. Pictured, Fiona, left, with sister Kellyann

Upon her diagnosis in January, doctors informed Fiona that she had between six months and a year to live. However, her health rapidly declined, and she sadly passed away just 11 weeks later on March 22.

Devastated by Fiona's sudden loss, her family and friends are urging others not to ignore concerning symptoms and to prioritize regular health check-ups.

Fiona's sister Kellyann shared with the Daily Record, "Fiona started experiencing severe stomach pains but put it down to just feeling unwell. Her stomach suddenly swelled out, and she couldn't keep anything down; she initially thought she was pregnant because of the way she was feeling. She was so swollen it did look as though she might be pregnant."

Adenocarcinoma, nicknamed the 'cancer of the cavities', is often only discovered during tests or treatments for other conditions. It accounts for around 90 per cent of all kidney and bowel cancers, 85 per cent of lung and a quarter of all cervical cancers, according to the Cancer Council, an Australian advice page

Adenocarcinoma, known as the 'cancer of the cavities,' is often detected incidentally during tests for other conditions. It affects various organs such as the kidneys, bowels, lungs, cervix, breasts, prostate, and stomach.

Symptoms can vary widely depending on the affected organ, and some patients may not experience symptoms until the cancer is advanced.

Treatment options for adenocarcinoma include surgery, chemotherapy, radiation therapy, and immunotherapy, depending on the tumor's location and size.

Fiona's family and friends emphasize the importance of regular health check-ups and prompt medical attention for unusual symptoms. Kellyann stresses, "Don't leave it until the last minute — get it checked by your GP as soon as you possibly can."
