A painful health condition on the rise in young women - and a radical treatment option - prevented Dolly Parton from becoming a mother.The country music icon passed away Tuesday at 80 years old following a brief battle with cancer, her representatives have confirmed. She is survived by six siblings and a large extended family of nieces and nephews, but the 9 to 5 hitmaker never had children of her own.More than four decades ago, Parton announced she had been diagnosed with endometriosis, a debilitating reproductive condition that causes tissues similar to those found in a woman's uterus to grow elsewhere in the body. This excess tissue causes excruciatingly painful periods, excess bleeding and, for up to half of those with the condition, infertility.Leading up to her diagnosis in 1982, at age 36, Parton described having to cancel a major tour due to severe abdominal and pelvic pain, as well as hemorrhaging. She also struggled with digestive distress.In 1984, the singer underwent a partial hysterectomy to remove her uterus - which may help alleviate some endometriosis symptoms - stopping menstruation. However, this meant she would never be able to become pregnant and have her own children. 'I can't have children physically,' she told Gloria Steinem in 1987. 'I love children. I don't know that it also wasn't God's will, you know, for me not to have kids.Legendary country music star Dolly Parton, who died this week at age 80, was open about her experience with endometriosis and infertility.
