investigation for the women with solitary palpable breast massesIn adolescents with a suspected fibroadenoma, reassurance and reexamination after the next menstrual cycle maybe appropriate.
However, adults with a palpable breast mass (such as this 24-year-old patient) ★require further evaluation with imaging because history and physical examination alone cannot reliably diagnose or exclude cancer in this population. breast surgeryreproductiveUWorld step2CK Sep 23, 2020, 5:46 AM HirotoShishido

placenta accreta/increta/percreta(morbidity adherent placenta)
Placenta accreta—placenta attaches to myometrium without penetrating it; most common type.
Placenta increta—placenta penetrates into myometrium.
Placenta percreta—placenta penetrates (“perforates”) through myometrium and into uterine serosa (invades entire uterine wall) reproductiveOBGYUWorld Jun 27, 2020, 12:53 AM HirotoShishido
manifestation/ risk factor of ovarian cancerPresent with abdominal distention, bowel obstruction, pleural effusion.
increased risk with advanced age(>55), infertility, endometriosis, PCOS, genetic predisposition (eg, BRCA1 or BRCA2 mutations, Lynch syndrome, strong family history).
reduced risk with previous pregnancy, history of breastfeeding, OCPs, tubal ligation. reproductive Jun 25, 2020, 9:01 PM HirotoShishido

Monitor response to therapy/relapse by measuring CA 125 levels (not good for screening).

target of colposcopyThe TZ(transformation zone) undergoes active cell division, young women are vulnerable to the oncogenic effects of human papillomavirus (HPV) infection and tobacco use.
Therefore, ☆the TZ is the most common site of cervical dysplasia/neoplasia. A colposcopy visualizes this area for biopsy.
