Some studies have shown that the risk of developing breast cancer is due to a combination of factors. The main factors that influence a person's risk include being female and getting older. Most breast cancers are detected in women aged 50 and older.
Some women develop breast cancer even though they have no other known risk factors. Having a risk factor does not mean a person will develop the disease, and not all risk factors have the same effect. Most women have some risk factors, but most women do not develop breast cancer. If you have risk factors, talk to your doctor about ways you can reduce your risk. reduce the risk and about the detection tests of this disease.
Risk factors for developing breast cancer that cannot be changed
Genetic mutations. Women who have inherited changes (mutations) in certain genes, such as BRCA1 and BRCA2, have a higher risk of developing breast and ovarian cancer. At Zogen, we offer a wide variety of studies DNA that can help you find out if you are a carrier of these genes.
Reproductive history. Starting menstruation before the age of 12 and menopause after the age of 55 expose women to hormones for a longer period, which increases the risk of developing it.
Having dense breasts. The dense breasts Dense breasts have more connective tissue than fatty tissue, which can sometimes make it difficult to detect tumors on a mammogram. Women with dense breasts are more likely to develop breast cancer.
Personal history of breast cancer or certain non-cancerous breast conditions. Women who have had breast cancer are more likely to develop it a second time. Some non-cancerous breast conditions, such as atypical hyperplasia or lobular carcinoma, can also lead to breast cancer. in situ, They are associated with a higher risk of developing breast cancer.
Family history of breast or ovarian cancer. A woman's risk of developing breast cancer is higher if her mother, sister, or daughter (first-degree relatives), or several family members on either her mother's or father's side, have had breast or ovarian cancer. Having a male first-degree relative with breast cancer also increases a woman's risk.
Previous radiotherapy treatments. Women who have received radiation therapy to the chest or breasts before the age of 30 (for example, for the treatment of Hodgkin lymphoma) have a higher risk of developing breast cancer later in life.
Exposure to the drug diethylstilbestrol. Diethylstilbestrol It was administered to some pregnant women in the United States between 1940 and 1971 to prevent miscarriage. Women who took diethylstilbestrol, or whose mothers took diethylstilbestrol when they were pregnant with them, have an increased risk of developing breast cancer.
Growing older. Most breast cancers are diagnosed after the age of 50.
Risk factors that can change
Being overweight or obese after menopause. Older women who are overweight or obesity They are at greater risk than those who are at a healthy weight.
Taking hormones. Some forms of hormone replacement therapy (those that include both estrogen and progesterone) taken during menopause may increase the risk of breast cancer if taken for more than five years. Certain oral contraceptives (birth control pills) also increase the risk.
Reproductive history. Getting pregnant for the first time after age 30, not breastfeeding, and never having a pregnancy that goes to term can increase the risk of breast cancer.
Drinking alcohol. Some studies show that a woman's risk of developing breast cancer increases with the amount of alcohol that he takes.
Staying physically active can help reduce the risk of developing breast cancer.
Not staying physically active. Women who do not stay physically active have a higher risk of developing breast cancer.
Research suggests that other factors, such as smoking, exposure to chemicals that can cause illness, and changes in other hormones due to working the night shift, may also increase the risk of breast cancer.
