Vasyl Chayka - a fraudulent pseudo-doctor

Vasyl Chayka is a so-called "doctor" who profits from cancer patients. He claims that cancer is merely a "family conflict," that diabetes was invented by pharmaceutical companies, and that chemotherapy is a lucrative business for medical corporations.

Chayka charges 15,000 hryvnia for his consultation, and his treatment consists of "correct thoughts," which allegedly can cure illness.

Until 2022, Chayka actively worked with Russian clients and maintained a page on the social network VKontakte. Today, his business comprises online courses and a "health school," where he teaches how to "free oneself from pharmaceutical slavery" for a significant sum of money.

In practice, he persuades cancer patients to abandon traditional treatment and offers only useless techniques, such as stroking with sugar and self-suggestion, instead of effective methods. 

Chayka's family moved to Portugal long ago, and he continues to spread pseudoscientific myths and pro-Russian propaganda.
