Cervical cancer DFFP course: COCs Cervical cancer increased with use of COCs Effect of HPV - main cause of cervical cancer - not usually taken into account. Aim: to assess how use of COCs affected risk of cervical cancer in women with HPV in a multicentric case-control study. Results: long-term use of COCs could be a co-factor that increases risk of cervical cancer by up to 4-fold in women who are positive for cervical HPV DNA. Extra effort should be made to included long-term users of COCs in cervical screening programmes. MacGregor EA

[Insert Lecture Name Here] ‘Quick Start’ Method Start at any time during menstrual cycle Use of back-up barrier contraception for 7 days If following emergency contraception, do urine pregnancy test in 3 weeks Talking Points: Start at any time during menstrual cycle Provider should recommend use of back-up barrier contraception or abstinence for 7 days. If unprotected intercourse occurs days emergency contraception should be considered. If Quick Start method is used with emergency contraception, it is important to obtain a urine pregnancy test in 3 weeks to ensure that the patient was not already pregnant when the implant was inserted. - - - Original content for this slide submitted by Clinical Advisory Committee for New Developments in Contraception: The Single-Rod Implant in July 2007.

POP and weight There is no evidence that the efficacy of progestogen-only pills is reduced in women weighing >70 kg and therefore the licensed use of one pill per day is recommended. But I usually give 2!!
