Sept 22 (Reuters) - Insurer Humana is among several companies looking to buy senior-care facility operator Cano Health, the Wall Street Journal reported on Thursday citing people familiar with the matter, sending Cano's shares up about 50%.

The talks are serious and a deal to purchase Cano could be struck in the next several weeks, the report said.

Cano had a market value of about $3 billion Thursday afternoon.
