“that [statistic] has not changed in 50 years,” says alicia tone, scientific advisor at occ. “our driving force is to try and change that. ovarian cancer is less common than breast cancer but it has a worse prognosis. breast cancer survival has improved over that same period whereas ovarian cancer has remained steady.”
“no reliable screening method” for ovarian cancer
because symptoms — which include abnormal uterine bleeding or postmenopausal bleeding, bloating, irregular or absence of menstrual cycle, feeling full fast after eating, changes in urinary habits — can mimic other conditions, ovarian cancer often goes undiagnosed.
when it is detected, it’s usually at a more advanced stage, leading to poor outcomes. current screening tools, which are woefully imperfect, include ct scan, mri, transvaginal ultrasound, or a blood test that measures the amount of a protein called ca-125 in the blood (many women with ovarian cancer have high levels of ca-125). it is not, as many mistakenly believe, diagnosed via pap test, which is used to screen for cervical cancer.
“ovarian cancer is so complicated that there is no reliable screening method,” says tone. “there have been countless trials including hundreds of thousands of women and, unfortunately, ca-125 and transvaginal ultrasound screening do not reduce death from ovarian cancer.”
