Lamar Odom -- Charity Accused of Stiffing Cancer Patients

Lamar Odom is facing allegations the tax exempt charity he created is being sketchy with its money ... and not donating ANY cash to cancer research, despite the charity's mission statement.

Lamar established the charity -- Cathy's Kids -- in memory of his mother, who died from cancer when he was 12 ... and initially stated that the purpose of the charity was to help underprivileged kids and raise money for cancer research.

But according to official records -- obtained by ESPN's "Outside the Lines" -- there is no evidence any of the money ever went to fight cancer.

There is proof, however, $1.3 million of the $2.2 million that was raised went toward funding two "elite" youth basketball teams -- the insinuation is that the kids on the teams were so good, they were already on college radars for scholarships and other financial help.

Of the remaining $900k, there is no evidence based on available documentation that any of it went to cancer research. In fact, according to OTL, there's no evidence whatsoever of where the money went.

Lamar sat down for an interview with ESPN producers -- he brushed off questions about where the money went by saying it was all his dough, despite the fact the money was raised through solicitations on his website, Khloe Kardashian's website and others.
