TRENTON, N.J. — Republican candidate for governor Assemblyman Jack Ciattarelli says he is undergoing treatment for cancer in his neck and is scaling back his campaign.

Fifty-five-year-old Ciattarellli, of Somerville, announced at the statehouse on Thursday he plans to resume campaigning full time in February and that there is a good chance he will beat the cancer.

He noticed a lump on his neck in early October. Doctors removed the cancer and lymph nodes on both sides of his neck in November.

He has been undergoing radiation since mid-December and says it’s no longer possible to continue to campaign every day.

He plans to continue to make phone calls and says that staff and surrogates will be campaigning.
