Here are the answers to your questions: 1. Differences between primary and secondary amenorrhea Primary amenorrhea is defined as the absence of menstruation by age 15 in individuals who have normal secondary sexual characteristics (like breast development), or by age 13 in individuals who lack secondary sexual characteristics. It means a person has never* had a menstrual period. Secondary amenorrhea is defined as the absence of menstruation for 3 or more consecutive cycles, or for 6 months, in an individual who previously* had regular menstrual periods. 2. Causes of amenorrhea The causes of amenorrhea can be broadly categorized: Physiological causes: Pregnancy (most common cause of secondary amenorrhea) Breastfeeding (lactational amenorrhea) Menopause Hypothalamic-Pituitary Dysfunction: Stress Excessive exercise Significant weight loss or anorexia nervosa Pituitary tumors (e.g., prolactinoma) Kallmann syndrome (a genetic condition causing absent puberty and sense of smell) Ovarian Dysfunction: Polycystic Ovary Syndrome (PCOS) Premature ovarian insufficiency (early menopause) Genetic disorders (e.g., Turner syndrome) Uterine or Outflow Tract Abnormalities: Asherman's syndrome (scar tissue in the uterus) Imperforate hymen or other congenital abnormalities blocking menstrual flow Cervical stenosis Other Endocrine Disorders: Thyroid disorders (hypothyroidism or hyperthyroidism) Adrenal gland disorders (e.g., Cushing's syndrome) 3. Stages of cervical cancer Cervical cancer is staged using the FIGO (International Federation of Gynecology and Obstetrics) system: Stage I: The cancer is confined to the cervix. Stage IA: Microscopic cancer. Stage IB: Visible cancer confined to the cervix. Stage II: The cancer has spread beyond the cervix but has not reached the lower third of the vagina or the pelvic sidewall. Stage IIA: Spread to the upper two-thirds of the vagina. Stage IIB: Spread to the parametrium (tissue next to the uterus). Stage III: The cancer has spread to the lower third of the vagina, to the pelvic sidewall, or has caused kidney problems (hydronephrosis), or involves pelvic/para-aortic lymph nodes. Stage IIIA: Spread to the lower third of the vagina. Stage IIIB: Spread to the pelvic sidewall or caused hydronephrosis. Stage IIIC: Involvement of pelvic and/or para-aortic lymph nodes. Stage IV: The cancer has spread to distant organs or to the bladder/rectum. Stage IVA: Spread to nearby organs like the bladder or rectum. Stage IVB: Spread to distant organs (e.g., lungs, liver, bones). Last free one today — make it count tomorrow, or type /upgrade for unlimited.
