: Breast and cervical cancer are both the most common and deadliest cancers among women in Morocco. The objective of this study is to determine the risk factors associated with breast and cervical cancer among Moroccan women in the region of Marrakech, Morocco. A cross-sectional, descriptive epidemiological study with analytical purposes was conducted among a sample of 400 women in Marrakech who attend health centers. This study was conducted in November 2019 during a screening survey for breast and cervical cancer. Detailed information on the risk factors of the two cancers studied was collected through a questionnaire. Univariate and multivariate analyses were used as statistical methods for the confirmation of these factors. Our results show that women with breast cancer are between 40 and 49 years old, and between 50 and 54 years old, married, widowed and also single, housewives, practicing handicrafts, have a very low level of education, contracted their first marriage before 30 years old, having breast pathologies and family history of cancer, using the pill as a contraceptive method, not having had multiple pregnancies, undergoing passive smoking, not drinking alcohol, not breastfeeding, having a BMI that tends to obesity and practicing a physical activity that does not meet the standards. On the other hand, women with cervical cancer are between 30 and 59 years old, have housekeeping jobs, are married and widowed, had their first marriage at an early age of 17 and 18, use the pill as a contraceptive method, have multiple pregnancies, do not smoke, do not drink alcohol, are breastfeeding, have a BMI that tends to obesity and are physically active. On the other hand, women with a diet high in meat and low in fruits and vegetables had a high risk of breast and cervical cancer. This work confirms the existence of associations between certain risk factors and the occurrence of breast cancer and cervical cancer in women in the Marrakech region. The results of our study suggest that research and monitoring of these risk factors should be coupled for more effective prevention. Furthermore, larger-scale prospective studies are needed to confirm and complete our results, which must determine even the fractions attributable to each risk factor..
