Lolita was born and grew up as a healthy child. In December 2023, the girl was diagnosed with severe abdominal pain. The girl was found to have a severe small cell carcinoma in the Belarusian Research Center for Pediatric Oncology, Hematology and Immunology. This is a rare disease that is known for its high aggression. Lolita has already undergone a complex course of treatment: 2 operations to remove the formation, 3 blocks of PCTs and a course of VDHT.

This study is being conducted at the Invitae Laboratory, San Francisco. Assistance was provided within the program «Chance».
