Singer Jessie J says results from tests following surgery to remove one of her breasts after an early cancer diagnosis show no spread of the disease.

In a social media post she wrote that she was crying “happy tears” after receiving the news.

In June she revealed her diagnosis and underwent surgery to remove her breast.

She thanked her 14 million followers for the “prayers, the love, the well wishes, the joy and all the positive energy”.

Jessie J has posted openly about her experiences of undergoing a mastectomy and received comments in support of her doing so.

On Monday she released a video, taken the night before her surgery, of her young son saying: “Mummy’s gonna be OK.”

“And… I am OK” she wrote, saying she’d received results showing no cancer spread.

The post was flooded with positive comments, including from celebrities like TV presenter Rochelle Humes. Singer Paloma Faith also offered her congratulations on the news.

Women who have been impacted by breast cancer also replied to the post. According to Cancer Research UK more than 56,000 women a year are diagnosed with the disease.

The popstar revealed she has “lots of healing to go” and is now awaiting an operation to “make these cousins look more like sisters”, referring to reconstructive surgery on her breast.

She signed off the post in good humour saying she is in the meantime changing her name to “The LopJess monster”.
