Cervical cancer stagin
- confined to cervix
- beyond cervix but not to pelvic wall or lowe 1/3 of vagina
- to pelvic wall or lowe 1/3 of vagina
- Invades bladder, rectum or METS
during puberty and pregnancy
the SCJ migrates down the os to the surface of the cervix. (ectopy)
The site where the columnar is undergoing metaplasia is called the:
transformation zone
Transformation zone
the area that cells under go metaplasia
SCJ
can move
migrates back up after puberty
Ectropian
can cause a lot of mucus
post coital bleeding
OCP can cause it
