Women over the age of 40: Your risk of breast cancer increases as you age
Earlier menarche or late menopause: The women with earlier menarche (before the age of 12) or late menopause (after the age of 55) had higher risks of breast cancers. Because the time of estrogen action is too long, easily lead to breast cancer.
Nullipara, Late childbirth, Do not breastfeed: The incidence of breast cancer in nonparous women or women who have not given birth until 35 is higher than those who give birth before the age of 30. One of the most clearly defined risk factors for breast cancer determined by the medical community is nonparous women because they lack the protection of progesterone and are more vulnerable to the stimulation of excessive estrogen. Besides, breast-feeding can decrease the risk of breast cancer in women, and the longer the time of women's breast-feeding is, the smaller the risk of breast cancer in them will be in the future.
High fat diet and Obesity: Intake of excessive high-protein and high-fat food can result in the elevation of estrogen and increased risk of breast cancer. Studies show that the risk of breast cancer in obese individuals is 1-1.5 times that in those with normal weight and that the risk of metastasis of breast cancer is twice as high as that in the latter. If the post-menopausal women are overweight or obese, their risk of breast cancer will be increased by 30%.
Feeling stressed or mood depression: Young urban women are faced with intense competitive pressure, and their minds are in the state of tension for a long time, leading to emotional instability. Besides, they often stay up late for working overtime,and thus their bodies can not get enough rest. Such an unhealthy lifestyle will lead to the endocrine imbalance and do some damage to their breasts, thereby increasing the risk of breast cancer.
Hyperplasia of mammary glands: Benign breast hyperplasia generally does not become malignant, whereas hyperplasia individuals with older age, a longer medical history, a larger mass and an ambiguous relationship between the mass and menstruation are prone to malignancy and thus they should go to hospital.
Receiving long-term estrogen therapy: The long-term hormone replacement therapy or other hormone replacement therapies in menopausal women can contribute to increased risk of breast cancer accordingly.
