Cervical cancer. Light micrograph (LM) of a section through an HSIL (High-grade squamous intraepithelial lesion) of the cervix showing endocervical glandular extension (red). Cervical cancer is a malignancy of the cervix, which is the lower part of the uterus (womb). It is the 2nd or 3rd most common cancer in women worldwide, and over half a million cases are diagnosed each year. When diagnosed the tumor is staged and treatment options chosen. The treatment may involve a combination of surgery, chemotherapy, and radiation therapy. In general, early detection and adequate treatment can help achieve a better outcome. Squamous Cell Carcinoma of Cervix usually occurs in women between the ages of 45 and 55 years. Infection with human papillomavirus is the most important risk factor predisposing one to cervical cancer. Magnification 40 x when printed at 10 cm.
