what are precancerous cells

Women who have been diagnosed with and treated for precancerous cells on the cervix may be at increased risk for developing and dying from cervical or vaginal cancer, new research suggests.

However, the researchers added that the overall risk of cervical or vaginal cancer is still low for women who have been diagnosed and treated for abnormal cells on the cervix.

The study authors analyzed data from more than 150,000 Swedish women who were treated for abnormal cells on the cervix. Of those, nearly 1,100 were later diagnosed with invasive cervical cancer and about 150 were diagnosed with invasive vaginal cancer. There were more than 300 deaths from cervical cancer and about 50 deaths from vaginal cancer.
