Teen's cancer misdiagnosed as anxiety, given months to live
14 Feb
Summary
- Madi was diagnosed with a rare adrenal cancer after symptoms were dismissed.
- Doctors initially mistook her condition for anxiety and depression.
- She received a prognosis of 15-18 months but is fighting for survival.

Madi Foster, a 20-year-old, was diagnosed with adrenocortical carcinoma, a rare cancer with odds of one-in-three million for her age group. Initially, at age 17, her symptoms of breathlessness and fatigue were misattributed to anxiety and depression by a GP.
Her condition worsened with back pain and sweating, leading to a hospital admission where a 15cm tumor wrapped around her spleen was discovered. After confirmation of the rare cancer, Madi had the tumor removed, but faced complications including septic shock.
In February 2024, the cancer returned in her abdomen and liver, with doctors estimating 15 to 18 months of life remaining. Her parents refused to accept this prognosis and sought treatment in Maryland, USA.
Thanks to over £45,000 in public donations for travel and accommodation, Madi underwent crucial surgeries in August 2024, including the removal of half her liver and radiation therapy. Madi remains hopeful and aspires to study oncology.
Madi's journey began in 2021 when she was a fit teenager playing rugby for Stafford Rugby Club. Her initial symptoms were subtle, leading to the misdiagnosis of anxiety and depression, with doctors even suggesting antidepressants.
By June 2023, her health significantly declined, characterized by profuse sweating and persistent back pain. Despite seeking medical attention multiple times, her worsening condition was initially attributed to a kidney infection. An ambulance was eventually called, leading to her hospitalization.
During her hospital stay, a consultant identified a large mass on an ultrasound scan. This revealed the 15cm tumor compressing her spleen. Subsequent tests confirmed it as adrenocortical carcinoma.
In September 2023, Madi underwent a major surgery to remove the extensive tumor. While the surgery was initially successful, complications arose in November 2023 when her abdomen filled with fluid, causing septic shock, multiple organ failure, and requiring three resuscitation attempts.
After recovering over several weeks, Madi was unable to undergo chemotherapy. A February 2024 scan revealed the cancer's recurrence, classifying her as stage four. Her parents, Nicola and Craig, actively searched for alternative treatments.
They discovered the National Institutes of Health in Maryland, USA, through a support group. Madi traveled to the US for treatment, with her first surgery on August 19, 2024, followed by another on August 27, 2024, which involved removing part of her liver and addressing tumors on her spine.
Madi's positive attitude has been a constant throughout her ordeal, and she draws strength from the immense support and donations she has received.
