Arizona Democratic Rep. Raul Grijalva announces cancer diagnosis

• His press statement didn't specify what kind of cancer, and a spokesperson told Axios his family hasn't released that information.
• The congressman hasn't voted in the House since Feb. 15 and has missed about 50 roll call votes since then, the Tucson Sentinel reported.

What he's saying: "This diagnosis has been difficult to process, but I am confident in the vigorous course of treatment that my medical team has developed, and I've begun my journey to fight this cancer," Grijalva said.

Between the lines: Grijalva has no plans to resign and will continue running for re-election, spokesman Ruben Reyes told Axios.

• The announcement came one day after the deadline for candidates to file their petitions to get on the July 30 primary election ballot.

The Congressman's office remains open, constituent services will continue uninterrupted and he's in regular communication with his staff as he undergoes treatment, Reyes said.

Catch up quick: Grijalva was first elected to the House in 2002 and is a former co-chair of the Congressional Progressive Caucus.

• He represents Arizona's 7th Congressional District, a Democratic stronghold that includes parts of Tucson, Yuma and western metro Phoenix.
