Alice Cancel, the candidate handpicked by Democratic bosses to replace convicted crook Sheldon Silver in the state Assembly, said Wednesday she hasn’t been campaigning because of illness.

Cancel, a party activist from the Lower East Side, disclosed her medical issues in response to a Post report saying she has been MIA on the campaign trail.

Silver, the former Assembly speaker, was convicted in a corruption scam last November. A special election to fill his seat will be held on April 19.

“I want to state on the record that I am not in hiding. Unfortunately, I have been sick and unable to keep to the intense campaign schedule required of all candidates participating in the special election,” Cancel said.

Cancel is a diabetic and has been struggling to control her blood sugar, said her husband, John Quinn.

“Stress will do that. It affects diabetics. It’s touch and go now,” he said.

“Is [the campaign] the best thing for her? Absolutely not. I worry about her,” he added.
