The secret was given out by an oligarch close to him.

The oligarch, who has close ties to the Kremlin, allegedly said that Vladimir Putin had developed blood cancer.

The informant said that the Russian president was “severely ill with blood cancer.
In addition, this informant added that “Putin completely destroyed the economy of Russia, the economy of Ukraine and many other world economies, because he has problems with his head.”
“One crazy person can turn the world upside down,” he says.
As UNIAN wrote, earlier there were rumors about Putin’s thyroid cancer or cancer in the abdominal cavity.
Recently, rumors about the illness of Russian President Vladimir Putin and his upcoming operation have been increasingly emerging in the media.
Russian human rights activist Mark Feigin noted that there is no direct evidence of the illness of the aggressor of the Russian Federation, because this is the main state secret, but this betrays his appearance. He says Putin is an old 70-year-old man with a load of diseases.

“He says Putin is an old 70-year-old man with a load of diseases.”
Not just Putin, but the whole of Russia is one cancerous tumour that needs chemotherapy.
Evil has its price and it is being exacted on one of it’s demons now. I guess the obvious question would be, is there one oligarch in putin’s toilet with any patriotism?
Wow I can only wish blood cancer. That’s painful and given the pain this scum sucker has given Ukraine, I think it’s a deserving end.
KARMA IS A BITCH!!!!
Cancers can spread to the brain. Putler already had a long standing disorder: psychopathy. Add those two afflictions together, plus the evil he was born with and you get a freak that only comes along once in a while : Lenin, Hitler, Stalin, Pol Pot, Mao and now putler.
Any disease is good for the evil sack of shit as long as it’s painful and deadly.
