Singer Carly Simon has publicly disclosed that she has been diagnosed with Parkinson's disease and a form of skin cancer. The 78-year-old 'You're So Vain' singer said in a statement that she is finally ready to speak about why she has been less visible in recent years. She revealed she has been battling basal cell carcinoma, a common skin cancer, and Parkinson's disease. 'I do not consider Parkinson's a gift or a blessing. It is neither. It is difficult, frustrating, and sometimes frightening,' Simon said. The announcement comes after years of relative quiet from the iconic singer, who rose to fame in the 1970s with hits like 'You're So Vain' and 'Anticipation.' Simon has not provided further details about her treatment or prognosis. Fans and fellow musicians have expressed support for the singer, who has been open about her health struggles in the past, including breast cancer and thyroid issues.
