An 'optimistic' Sonali took to Instagram to release a statement where she said she is "determined to fight every step of the way."
"Sometimes, when you least expect it, life throws you a curveball. I have recently been diagnosed with a high grade cancer that has metastasised, which we frankly did not see coming. A niggling pain led to some tests, which led to this unexpected diagnosis," wrote the 43-year-old.
She further thanked her family and friends for being her support system and said she is undergoing treatment in New York.
"My family and close friends have rallied around me, providing the best support system that anyone can ask for. I am very blessed and thankful for each of them. There is no better way to tackle this, than to take swift and immediate action. And so, as advised by my doctors, I am currently undergoing a course of treatment in New York"
"We remain optimistic and I am determined to fight every step of the way. What has helped has been the immense outpouring of love and support I've received over the past few days, for which I am very grateful."
"I'm taking this battle head on, knowing I have the strength of my family and friends behind me," concluded Sonali.
