Meghan Trainor canceled the remaining dates on her MTrain tour Tuesday.

The 21-year-old singer announced the news following her second vocal cord hemorrhage this summer. Trainor previously postponed two dates on the tour after her first vocal cord hemorrhage in early July.

"To all my fans - I was being careful and taking precautions, but I have hemorrhaged my vocal cord again," she wrote on Instagram. "I got bronchitis & have been coughing a lot & that pushed it over the edge. Sadly, I will need to cancel the remainder of my tour and get surgery to finally fix this once and for all."

"I am devastated, scared, and so sorry," she said. "I LOVE touring and seeing your beautiful faces every night. I am determined to do what it takes to get better and come back around stronger than ever. I love you, and thank you for all of your understanding, love and support."
