90,000 (2015) [ 5] Uterine cancer, also known as womb cancer, includes two types of cancer that develop from the tissues of the uterus. [ 3] Endometrial cancer forms from the lining of the uterus, and uterine sarcoma forms from the muscles or support tissue of the uterus. [ 1][ 2] Endometrial cancer accounts for approximately 90% of all uterine ...
The third trimester is defined as starting, between the beginning of week 28 (27 weeks + 0 days of GA) [36] or beginning of week 29 (28 weeks + 0 days of GA). [4] It lasts until childbirth . Timeline of pregnancy, including (from top to bottom): Trimesters, embryo/fetus development, gestational age in weeks and months, viability and maturity stages
Specialty. Obstetrics and gynaecology. A vanishing twin, also known as twin resorption, is a fetus in a multigestation pregnancy that dies in utero and is then partially or completely reabsorbed. [ 1][ 2] In some instances, the dead twin is compressed into a flattened, parchment-like state known as fetus papyraceus. [ 3]
Fetus in fetu (or foetus in foetu) is a rare developmental abnormality in which a mass of tissue resembling a fetus forms inside the body of its twin. An early example of the phenomenon was described in 1808 by George William Young. [ 1] There are two hypotheses for the origin of a "fetus in fetu". One hypothesis is that the mass begins as a ...

Gestational trophoblastic disease ( GTD) is a term used for a group of pregnancy-related tumours. [ 1] These tumours are rare, and they appear when cells in the womb start to proliferate uncontrollably. The cells that form gestational trophoblastic tumours are called trophoblasts and come from tissue that grows to form the placenta during ...
Large for gestational age ( LGA) is a term used to describe infants that are born with an abnormally high weight, specifically in the 90th percentile or above, compared to other babies of the same developmental age. [ 1][ 2][ 3] Macrosomia is a similar term that describes excessive birth weight, but refers to an absolute measurement, regardless ...
Gestational age: 3 weeks and 0 days until 3 weeks and 6 days old. 22–28 days from last menstruation. Embryonic age: Week nr 2. 1 week old. 8–14 days from fertilization. Trophoblast cells surrounding the embryonic cells proliferate and invade deeper into the uterine lining. They will eventually form the placenta and embryonic membranes.
