Cobie Smulders opened up about her battle with ovarian cancer. She was diagnosed at the age of 25 and feared the cancer would lead to infertility. Luckily, she had a “great” oncologist to help her, and her surgeon was able to save her ovaries enough for her to have two children. Now, she is working with oncology-focused pharmaceutical company Tesaro for their “Not On My Watch” campaign to “educate and empower women with recurrent ovarian cancer.”
