Christian is 8 years old, an active and purposeful boy. He studies well at school, makes friends with his classmates, plays checkers and soccer with them. The boy likes to study different plants under a microscope and dreams of becoming a biologist when he grows up.
In December last year Christian got pneumonia, after which his shoulder started to hurt and he suddenly had a fever. After a CT scan, a volumetric mass was found. The boy was sent to the Russian Children's Clinical Hospital, where after examination it was determined that he had sarcoma. Christian patiently endures hard treatment, now he has overcome the surgery and 3 courses of chemotherapy.
For further treatment it is necessary to do a genetic study “Childhood Hereditary Tumors” in order to exclude hereditary syndromes of predisposition to the tumor. This will help to understand the nature of the disease and select an effective treatment.
