Age is one of the risk factors, because the chance of gene mutations increase with time. Therefore, women over 50 years of age have a higher chance of developing breast cancer. Additionally, women who have gone through menopause are also at a greater risk for it. Because of this, it is very important that women over 50 years of age are screened for breast cancer regularly.
While medicines are safe to consume, some of them, such as contraceptive pills, may put women at higher risk of breast cancer. This does not mean that taking contraceptive pills is directly linked with breast cancer. It may be one of the contributing factors that are related to women developing cancer. The risk reduces significantly once women stop taking them.
3. Family History
This is one of the common reasons why some women may develop breast cancer. If women in your family have had breast cancer, you can also be at risk. This is because it is likely that the BRCA1 and BRCA2 genes (they are genes that increase the likelihood of breast cancer) have been passed down to you. Not only this, but these genes are also found in ovarian cancer. If you have a family history of these two cancers, your risk of developing a breast cancer may be higher.
Stress, alcohol, and a sedentary lifestyle may also contribute to breast cancer in women. As such, obesity may also increase the risk of getting it because being overweight may indicate high estrogen levels.
