What are the risk factors for breast cancer?


Pregnancy is a risk factor for breast cancer, especially if it is the first pregnancy after the age of 35. However, while it increases the risk, the hormones involved may actually help prevent the disease. Pregnancy stimulates breast cells to enter their final stage of development, which may protect against breast cancer.

A family history of breast cancer is also a risk factor. Women from poorer areas have a higher risk of developing breast cancer than those from richer backgrounds. This may be because of differences in diet and other health conditions. Women from poorer backgrounds are also more likely to develop advanced stages of the disease and to die from it. Genetics, lifestyle factors, and tumor biology may also play a role.

Although breast cancer is a disease that strikes older women, it is still rare among women in their teens. Almost all new cases of the disease are found in women over 40. Other risk factors include a personal history of the disease. Despite the fact that these aren’t definite causes of breast cancer, some women with these risk factors should make lifestyle changes to reduce their risk of developing it.

While there is no conclusive evidence to indicate a link between breast cancer and ethnicity, there are several ethnic groups that are more prone to it. Women of European and Ashkenazi Jewish ancestry are at higher risk than other races, while black and Hispanic women are less likely to develop the disease. Furthermore, taller women are more likely to develop breast cancer than those who are shorter.
