Now, Wilson is looking forward to going on her first tour with her band in good health. "I'll start in New York at the Cafe Carlyle for two weeks on February 23rd," she explained to PEOPLE of the tour. "Then I have a couple weeks off, and then I start again at the end of March. I'll go through all the April and part of May. It's going to be hilarious. Me on a tour bus with my band members," she laughed.
Her husband, Tom Hanks, plans to accompany her on the road. "He's already said, 'I am coming on the tour bus!' So I had to get one with a bigger bed. So that was important. He's coming. He's going to be on tour ... He's a roadie," she joked.
In addition to being excited for her first ever cross country drive, Wilson says her recent recovery has added meaning to the tour. "I feel really blessed and very lucky," she says, adding, "Part of the reason for going on tour is that I want to show people that you can have cancer, and you can still be out there doing what you love to do, and it's not a death sentence like it used to be."
