After mom took DES in pregnancy is it possible to get cervical cancer from this?

Vaginal cancer. Des is associated with the development of vaginal adenosis and clear cell carcinoma of the vagina in the offspring of women who took des during pregnancy. These lesions often occur in girls and young women. Carcinoma of the cervix may occur. Des use was discontinued about 30+ years ago. Regular checks ups with your doctor are advised, even without des exposure.
No. Des given during pregnancy was associated with a rare form of vaginal cancer called clear cell carcinoma in about 1% of exposed female offspring. Des was last given in the 1960s or in rural areas the early 1970s, so most of the risk period for that disease has passed.
