Breast cancer:
What are your risks?

Breast cancer accounts for more than 11 000 deaths in France each year. Different causes may increase your risk of developing this disease. If some are innate, others are modifiable. See them without waiting! The most important thing you can do is go to a doctor as soon as symptoms apear,especially that the early stages of breast cancer are asymptomatic.

Genetic and also factors coming from the enviroment that may lead to the development of cancer. By browsing, we can emphasize the importance of scientifically established factors, or those who are the subject of considerable controversy.
Age, genetic factors and family history

Young motherscan have breast cancer, it can occur at any age, her risk of occurrence increases with age. It doubles roughly every 10 years until menopause. In addition, it continues to increase but less intensity.

If multiple cases of breast cancer are already known in your family, it can increase your own chance of developing the disease. In developed countries, between 5 and 10% of cases are linked to genetic predisposition. This is equivalent annually in France in 1 700 to 3 400 cases.

Specifically, the risk of cancer is twice as high among women whose close relatives (sisters, mothers or daughters) have developed breast cancer before age 50. The younger age of onset, the greater the danger is great. Thus, a woman whose sister developed cancer at the age of 30-39 years has a cumulative risk of 10% of itself be affected before 65 years, but this risk falls to 5% if her sister was aged 50-54 years at diagnosis. The risk also increases when more relatives are affected. A woman with two relatives with breast cancer including one aged under 50 at diagnosis is 25% risk of developing cancer before 65 years.1.

The origin of this danger, we found some genes, the best known are the BRCA1 and BRCA2 (for Breast Cancer which means breast cancer). These forms are alone responsible for 95% of familial forms of hereditary breast and ovarian cancer, and 65% of familial breast cancer alone.But other predisposing genes for breast cancer were identified.

Specifically, if multiple cases of breast cancer in your family you are afraid of a genetic predisposition, talk to your doctor or your gynecologist. This may if necessary refer you to one consultations oncogenetic (genetics applied to oncology).
Puberty, pregnancy, lactation and menopause

Precocious puberty and late menopause increase the susceptibility to be affected by breast cancer. A woman whose menopause happens naturally after age 55 are twice as likely as women affected by menopause before age 45.
