People at risk
A number of non-modifiable to increase significantly – from the general population – the risk for a person to be achieved in this cancer. A number of non-modifiable to increase significantly – from the general population – the risk for a person to be achieved in this cancer.
* Sex. Gender. Less than 1% of cases of breast cancer are men, and they generally have more than 60 years. Less than 1% of cases of breast cancer are men, and they generally have more than 60 years.
* Age. The disease rarely affects women under 30 years. The disease rarely affects women under 30 years. But the more a woman’s age, the risk of developing breast cancer increases. But the more a woman’s age, the risk of developing breast cancer increases.
* Benign breast disease with atypical cells. Benign breast disease with atypical cells. Women who have already suffered from this condition are more likely to be suffering from cancer. Women who have already suffered from this condition are more likely to be suffering from cancer.
* Inheritance. Heredity. In a research conducted between 1976 and 1988 by doctors at the Harvard School of Public Health at 117 988 women 30 years to 55 years, the risk of suffering from breast cancer were quantified in the following way: In a research conducted between 1976 and 1988 by doctors at the Harvard School of Public Health at 117 988 women 30 years to 55 years, the risk of suffering from breast cancer were quantified as follows:
-7% When the mother and sisters have never suffered from this cancer; -7% When the mother and sisters have never suffered from this cancer;
-10% When the mother has already suffered; -10% when the mother has already suffered;
-12.5% When the mother was affected before age 50; -12.5% when the mother was affected before age 50;
-13% When a sister has suffered; -13% When a sister has suffered;
-17% When the mother and sister have suffered. -17% When the mother and sister have suffered.
Furthermore, it is believed that 5% to 10% of breast cancers are caused by an abnormality of one or other of two genes called BRCA1 and BRCA2. Furthermore, it is believed that 5% to 10% of breast cancers are caused by an abnormality of one or other of two genes called BRCA1 and BRCA2. In fact, among women with one of these defective genes, there are 56% to 87% risk of suffering from breast cancer, and 20% to 60% suffering from ovarian cancer. In fact, among women with one of these defective genes, there are 56% to 87% risk of suffering from breast cancer, and 20% to 60% suffering from ovarian cancer. There are tests to see if a woman from a family at risk is itself a carrier of the defective genes. There are tests to see if a woman from a family at risk is itself a carrier of the defective genes.
The following conditions may increase the risk of breast cancer compared with the general population:
* Nulliparity. The fact of not having had children or have given birth after 30 years. The fact of not having had children or have given birth after 30 years.
* High levels of estrogen. High levels of estrogen. Estrogens act on cells of the breast (and the reproductive system) and cause them to proliferate. Estrogens act on cells of the breast (and the reproductive system) and cause them to proliferate. Some women have naturally high levels of estrogen (for example, people with extra weight), or are exposed longer because they have started menstruating early, or have ended later.
