State Senator Thomas Libous has confirmed that the prostate cancer he's been battling for the past four years has spread.

Gannett's Albany bureau on Wednesday reported doctors discovered tumors in his lungs last year.

Libous has been undergoing a range of cancer treatment since 2009 and another round of chemotherapy is planned.

The Binghamton Republican - who turned 60 in April - has continued working in his Senate leadership position while being treated in New York City.

Libous said he's evaluating his future in the Senate but he's made no decision as to whether he'll seek another term next year.

Libous was first elected to the state Senate 25 years ago. Before that, he served on Binghamton City Council.
