It causes more deaths than any other cancer of the female reproductive system. [24] Among women it ranks fifth in cancer-related deaths. [25] The typical age of diagnosis is 63. [2]
Stage III: The cancer has spread beyond the pelvis into the abdomen and to the retroperitoneal lymph nodes (located at the back of the abdomen). The substages are characterized by the relative size of the tumor. [22] Note: Stage II ovarian cancer will also be declared if the cancerous cells have spread to the liver.
Oocytes are then able to mature within the follicle through meiosis. In humans with ovaries, this process occurs continuously, as they are born with a finite number of follicles (between 500,000-1,000,000 follicles), and about 99% of follicles undergo atresia. [4] Only one follicle will be mature enough to release an egg and may be fertilized. [5]
An oocyte (/ ˈ oʊ ə s aɪ t /, oöcyte, or ovocyte is a female gametocyte or germ cell involved in reproduction. In other words, it is an immature ovum, or egg cell. An oocyte is produced in a female fetus in the ovary during female gametogenesis. The female germ cells produce a primordial germ cell (PGC), which then undergoes mitosis ...
The resulting zygote then gives rise to an embryo, which will grow into a new diploid individual, known as a sporophyte. In seed plants, a structure called the ovule contains the female gametophyte. The gametophyte produces an egg cell. After fertilization, the ovule develops into a seed containing the embryo. [14]
