MONROE, La. (AP) — One of Louisiana's longest-serving state lawmakers has been diagnosed with prostate cancer.

Sen. Francis Thompson, a Delhi Democrat who has served more than 40 years in the Louisiana Legislature, tells The News-Star he will have surgery Dec. 13 in Baton Rouge to remove the cancer.

The 76-year-old Thompson says he's "a little anxious, but the Lord tells us to turn over our problems to him and that's what I've done." He says he expects to be "around for a long time."

Thompson was elected to the Louisiana House in 1974. He has served with seven governors and has the second-longest tenure of anyone in the Legislature. The only lawmaker with a longer stint is his friend, Senate President John Alario, a Westwego Republican who joined the House two years before Thompson.
