Osteosarcoma of the pelvic bone❗URGENT HELP for Paulina❗

When pain turned out to be the beginning of the fight for health

Paulina is undergoing treatment in Warsaw, and her illness began very inconspicuously. At the beginning of September 2025 , she experienced pain in her left buttock during a physical education class. It was not severe, did not restrict her movement, and did not cause much concern. However, the pain increased week by week. It was accompanied by radiating pain in her left leg, severe discomfort when sitting, and then the first neurological symptoms and limping. That was when intensive diagnostics began.

In October 2025, Paulina was consulted by many specialists—a pediatrician, physical therapist, orthopedist, rheumatologist, surgeon, and neurologist. Numerous imaging tests were performed. It was only a contrast-enhanced MRI scan, performed in early November, that revealed the cause of the pain: a large tumor involving the pelvic bone, the left hip joint, and infiltrating the surrounding muscles. A few days later , a biopsy of the tumor was performed, and on November 24, 2025, Paulina was admitted to the oncology ward. Throughout most of November and December, the pain was so severe that she was unable to sit or walk. The diagnosis was osteosarcoma of the pelvic bone.

Treatment full of uncertainty

Treatment began in November. Unfortunately, the first chemotherapy did not bring any improvement – the pain persisted and imaging tests showed that the tumor had clearly grown. This forced an immediate change in the treatment protocol. The new chemotherapy, administered in mid-December, brought the long-awaited improvement. On Christmas Eve, the pain in her leg completely disappeared, and tests showed calcification of the tumor, which is a positive sign of effective treatment. Paulina underwent two more cycles of the same chemotherapy, each lasting several days. At the end of February 2026, a very serious operation is planned, involving the removal of cancer-affected bones and tissues and the implantation of bone implants. After the operation, Paulina will undergo long-term rehabilitation and further oncological treatment.

Chemotherapy is extremely toxic to the body. Paulina struggles with nausea, loss of appetite, and extreme weakness. Her blood counts often drop dramatically, requiring multiple transfusions, antibiotic therapy, and strict isolation to protect her from infection. Every day brings uncertainty: will she develop a fever, will her blood results allow her to continue treatment, will she have the strength to get out of bed? The family's daily life revolves around the IMID hospital in Warsaw, their home in Kąty Wrocławskie, and Przylądek Nadziei (Cape of Hope) in Wrocław, which supports Paulina when her blood parameters drop. Paulina's mother is with her all the time. Her father has taken on the role of logistical support and care for Paulina's older brother, Tomek, a second-year high school student, while her mother and Paulina are in the hospital.

Childhood frozen in mid-step

Paulina has not been attending school since the end of November. Since January 2026, she has been studying remotely on an individual basis. The management and teachers at Primary School No. 1 in Kąty Wrocławskie are doing everything they can to help her get through this difficult time. Paulina had to give up what she loved most—dancing. For years, she was a member of the MASKA modern dance group at GOKiS. After the summer holidays, she danced for only two months. She also gave up pottery and meeting her peers. From an active, cheerful girl, she became a child confined to the four walls of her home and hospital. Her older brother is very upset about his sister's illness and asks about every test result, worries and tries to cheer her up.

Biggest challenges

The biggest unknown is each new day. Monitoring blood parameters, struggling to ensure proper nutrition despite a lack of appetite, balancing the parents' professional lives with treatment and childcare – everything is subordinated to one goal: Paulina's health. The funds raised will be used for non-refundable treatment and the costs of long, intensive rehabilitation, which will be crucial after the planned surgery. Every donation is real help on this difficult, long road and support for Paulina, who is fighting with great strength and courage to recover, dance, and have a normal childhood.
