Most HPV infections don't lead to cancer. But some types of genital HPV can cause cancer of the lower part of the uterus that connects to the vagina (cervix). Other types of cancers, including cancers of the anus, penis, vagina, vulva and back of the throat (oropharyngeal), have been linked to HPV infection.
USA has 50 states since 1959. The flag has 50 stars, one for each state. The District of Columbia is a federal district, not a state. Many lists include DC and Puerto Rico, which makes for 52 states and other jurisdictions.
From 1794 until 1817, at least 4 more states had been added to the country. The flag, however, stayed the same until 1818 when Congress decided that the flag should have 13 stripes to honor the 13 original colonies and a white star to represent each state in the Union. What Do The Colors Of The American Flag Mean? Today, the flag continues to carry the 13 red and white alternating stripes and now displays 50 white, 5-pointed stars against a blue background, representing the 50 states.
