ABSTRACT
Breast cancer This has a high incidence and therefore it must inevitably be expected to develop in women whether or not they use COCs. As recognized risk factors for breast cancer include early menarche and late age of first birth, use of COCs by young women was bound to receive scientific scrutiny. However, increasing age is the most important risk factor (Figure 2), so if there is a real causative link with use of the Pill, use by older women will obviously lead to more attributable cases.
