Relative risk, such as "A woman is more than 100 times more likely to develop breast cancer in her 60s than in her 20s." [6] Fraction of incidences occurring in the group having the property of or being exposed to the risk factor, such as "99% of breast cancer cases are diagnosed in women." [7]
The risk of getting breast cancer increases with age. A woman is more than 100 times more likely to develop breast cancer in her 60s than in her 20s. [4] The risk over a woman's lifetime is, according to one 2021 review, approximately "1.5% risk at age 40, 3% at age 50, and more than 4% at age 70." [5]
Oral infection with high-risk carcinogenic HPV types (most commonly HPV 16) [41] is associated with an increasing number of head and neck cancers. [69] [53] [70] [71] This association is independent of tobacco and alcohol use. [71] [72] [73] The local percentage varies widely, from 70% in the United States [74] to 4% in Brazil. [75]
Gonorrhoea is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. [1]The World Health Organization (WHO) estimated that, in 2016, the global incidence rate was 20 per 1000 women and 26 per 1000 men, totaling 86.9 million new gonococcal infections among people between 15 and 49 years old.
Although less data is available, the prevalence of HPV infection is at least as common among men as among women, with 2004 estimates of about 27% among US women aged 14–59. [8] HPV oral infection precedes the development of HPV+OPC. [8] [5] Slight injuries in the mucous membrane serve as an entry gate for HPV, which thus works into the basal ...
However, no increase in seroprevalence was associated with age in women over 40 years old in Brazil—HSV-2 prevalence was estimated at 50% among women aged 40–49, 33% among women 50–59, and 42% among women over 60. Women in Brazil are more likely to acquire an HSV-2 infection if their male partners had history of anal sex and had many ...
