"There is concern for... view more... (2002-04-02)
Risk of HIV transmission highest early in infection

HIV-1-Positive Women At Increased Risk Of Genital Cancer
A study in this week's issue of THE LANCET suggests that women who are HIV-1 positive are at an increased risk of invasive genital cancer.
