A 40-year-old woman is fighting for her life after a persistent cough and fatigue were initially misdiagnosed, leading to a late-stage discovery of aggressive breast cancer. Ella Cieslak's cancer had spread to her lungs, lymph nodes, liver, spine, and brain by the time it was diagnosed.
Cieslak had sought medical attention multiple times over nine months, starting in September 2025, for a range of symptoms including stomach pain, itchy skin, changes in bowel habits, fatigue, and pain in her left side. She visited her GP surgery on three separate occasions, each time seeing a nurse who performed blood tests. These tests, which included checks for liver function, iron, vitamin B12, and folate levels, consistently returned normal results. At one point, she was treated for a common stomach infection, Helicobacter pylori.
By February 2026, her symptoms had progressed to include constant pain down her left side, unusually swollen veins in her limbs, and extreme fatigue. In March, further blood tests checking her thyroid, liver, and kidney function also came back normal. Cieslak began to suspect something was seriously wrong but was repeatedly told her blood work was fine.
In May 2026, a relentless dry cough developed, becoming so severe it impacted her sleep, ability to walk, and speak. She finally secured an appointment with a GP on May 21, who, concerned by the combination of symptoms, ordered a chest X-ray. The X-ray revealed abnormalities, and Cieslak was prescribed antibiotics while specialists considered possibilities like tuberculosis or other lung infections.
Further investigations, including a CT scan, an MRI of her brain, and a PET scan, raised more serious concerns. A radiologist delivered the devastating news that she had stage four breast cancer. A subsequent biopsy confirmed it was HER2-positive breast cancer, an aggressive form characterized by an overproduction of the HER2 protein, which fuels rapid tumor growth.
Cieslak had not felt any lump or noticed changes in her breast, a common warning sign. Approximately one in six women diagnosed with breast cancer after developing symptoms do not initially present with a lump, according to a UK study. Symptoms can include nipple changes, breast pain, or skin changes, but more rarely, the first signs can be due to cancer that has already spread.
Just four days after her diagnosis, Cieslak began chemotherapy with docetaxel, along with targeted drugs trastuzumab and pertuzumab. However, doctors also had to address the 23 tumors identified in her brain. She underwent Gamma Knife radiosurgery, a precise form of radiation treatment, in Bristol.
Doctors have informed Cieslak that her cancer is incurable, with treatment focused on managing the disease for as long as possible. She now relies on friends for support and has had to relinquish much of her independence, unable to work or drive due to the brain tumors. Despite the challenges, Cieslak remains determined to fight and holds onto future aspirations, including attending her favorite band's concert and celebrating her 50th birthday in the Maldives.
