Jessie J stepped up despite discomfort from breast biopsies

A biopsy removes a piece of tissue for examination. "I was in some discomfort but was so excited to perform that I didn't want to cancel," the singer wrote on Instagram. The video shows Jessie J talking to the audience between her songs during her performance in April. She jokes, including about her "huge, perfect tits." The singer said she had a hard time keeping her health issues to herself during these conversations. "Laughing and joking around" is one way the singer copes with the news.

Jessie J will undergo surgery after a performance in London on June 15. "I'll be off the grid for a bit after Summertime Ball for my surgery, and then I'll be back with huge boobs and more music," she said on Wednesday.
