The chairman of the House's tax-writing committee says he's been diagnosed with a "very early, highly treatable and curable type" of cancer.

GOP Rep. Dave Camp of Michigan says in a statement that doctors found non-Hodgkin lymphoma during a recent physical. Camp says he'll continue in Congress and retain his committee chairmanship during chemotherapy.

Non-Hodgkin lymphoma is a cancer that begins in the cells of the immune system. The 59-year-old Camp says he has large B-cell lymphoma. B-cells are a type of white blood cell that helps fight infections.

Camp, who's served since 1991, has said he wants to combine a push to head off pending tax increases with ways to force Congress to revamp the tax code next year.
