Positron emission tomography (PET) or PET-CT scan. A PET scan is usually combined with a CT scan (see above), called a PET-CT scan . However, you may hear your doctor refer to this procedure just as a PET scan. A PET scan is a way to create pictures of organs and tissues inside the body. A small amount of a radioactive sugar substance is injected into the patient’s body. This sugar substance is taken up by cells that use the most energy. Because cancer tends to use energy actively, it absorbs more of the radioactive substance. A scanner then detects this substance to produce images of the inside of the body.
Vaccination should occur before sexual activity to offer the full benefit of the vaccine. The CDC recommends that 11- to 12-year-old girls receive the HPV vaccine, and young women ages 13 through 26 should get the vaccine if they did not receive any or all doses when they were younger. Gardasil is also approved for use in males aged 9 to 26, and the CDC recommends Gardasil for all boys aged 11 or 12 years, and for males aged 13 through 21 years who did not receive the full three vaccination series. Men can receive the vaccine up to age 26.
