Cancer
any of various conditions characterized by the uncontrolled cell division that tend to invade surrounding tissue and metastasize to new body sites due to an accumulation of anomalies within a cell. These anomalies can be congenital or acquired after birth through environmental factors. Normal tissue is growth-limited, i.e., cell reproduction is equal to cell death. Feedback controls limit cell division after a certain number of cells have developed, allowing for tissue repair but not expansion. Tumor cells are less responsive to these restraints and can proliferate to the point where they disrupt tissue architecture, distort the flow of nutrients, and otherwise do damage. Most cancers are named for the type of cell that makes up the cancer (lymphoma - a cancer originating in lymphatic tissue, sarcoma - a cancer originating in the connective tissue of bone or muscle, carcinomas - a cancer originating in skin, digestive tract or glands, etc.) or the organ in which they begin (breast cancer, cervical cancer, skin cancer, bone cancer, etc).

Cervical mucous
protective mucous secreted by the glands within the uterine cervix. The viscous, slippery character of the secretions changes with the phases of the menstrual cycle under the influence of the female sex hormones. Most of the time this thick mucus plug prevents spermatozoa and bacteria from entering the uterus. At midcycle, close to ovulation, under the influence of estrogen, the mucus becomes thin, watery, and stringy (similar to raw egg white) to allow spermatozoa to pass into the uterus. In the rest of the time cervical mucus is thick and cloudy and indicates a time when conception is less likely. Interpreting these changes along with the basal body temperature is used in natural birth control methods to chart fertility.
Cervical polyp

Cervical polyps are associated with inflammation of the cervix and with an abnormal response to the female hormone estrogen.
