Progestin-only pills are useful for women who are unable to take regular oral contraceptives that contain estrogen due to their side-effects or to the exacerbation of existing conditions like migraine. Daily intake thickens the cervical mucus thus preventing the entry of sperm. The dose of progesterone is not sufficient to inhibit ovulation or reduce luteinising hormone (LH) secretion. Although it decreases tubal motility, this is more related to the occurrence of ectopic pregnancy. It may make the endometrium out-of-phase but not unfavorable for implantation.

BCC can be divided into localised (nodular; nodulocystic; cystic; pigmented and naevoid) and generalised (superficial: multifocal and superficial spreading; or infiltrative: morphoeic, ice pick and cicatrizing). Nodular and nodulocystic variants account for 90% of BCC. Typical naevi can be sporadic or familial (familial atypical multiple mole-melanoma [FAMMM] syndrome). Possession of more than five lesions confers a relative risk of melanoma six times greater than usual; within FAMMM syndrome, they confer a 100% risk of malignant melanoma and patients with FAMMM syndrome should be screened for melanoma 6-monthly, lifelong.
