Cervical squamous intraepithelial lesion (SIL), previously called cervical intraepithelial neoplasia (CIN), is a form of dysplasia that can progress to cervical cancer. The term carcinoma in situ may be used interchangeably with high-grade SIL. [8] Ductal carcinoma in situ of the breast is the most common precancer in women. Bowen's disease is ...
Cervical cancer is the 12th-most common cancer in women in the UK (around 3,100 women were diagnosed with the disease in 2011), and accounts for 1% of cancer deaths (around 920 died in 2012). [148] With a 42% reduction from 1988 to 1997, the NHS-implemented screening programme has been highly successful, screening the highest-risk age group (25 ...
Progression to cervical carcinoma in situ (CIS) occurs in approximately 11% of CIN 1 and 22% of CIN 2 cases. Progression to invasive cancer occurs in approximately 1% of CIN 1, 5% of CIN 2, and at least 12% of CIN 3 cases. [3] Progression to cancer typically takes 15 years with a range of 3 to 40 years.
Most cases of adenocarcinoma are associated with smoking; however, among people who have smoked fewer than 100 cigarettes in their lifetimes ("never-smokers"), [11] adenocarcinoma is the most common form of lung cancer. [12] A subtype of adenocarcinoma, the bronchioloalveolar carcinoma, is more common in female never-smokers, and may have a ...
Cervical cancer is a type of gynecological cancer that begins from cells lining the cervix, the lower part of the uterus. [14] Cervical cancer begins when the cells that line the cervix become abnormal and grow in a pattern that is atypical for non-cancerous cells. [14] Cervical cancer is typically first identified with an abnormal pap smear. [14]
Around 11,500 cases of cervical cancer are diagnosed each year in the U.S., according to the Centers for Disease Control and Prevention. About 4,000 Americans die annually from the cancer. About ...
Sometimes, the term "precancer" is also used for carcinoma in situ, which is a noninvasive cancer that has not grown and spread to nearby tissue, unlike the invasive stage. As with other precancerous conditions, not all carcinoma in situ will become an invasive disease but is at risk of doing so.
High-grade squamous intraepithelial lesion (HSIL or HGSIL) indicates moderate or severe cervical intraepithelial neoplasia or carcinoma in situ. It is usually diagnosed following a Pap test. In some cases these lesions can lead to invasive cervical cancer, if not followed appropriately. [citation needed] HSIL does not mean that cancer is present.
