Introduction
Today, the number of breast cancer is increasing day by day in the world so we need to know the basic way to understand it, what causes it, and how to avoid it, so read till the end to know the things.
Genetic Factors
BRCA1 and BRCA2 mutations
Certain genetic mutations, such as those in the BRCA1 and BRCA2 genes increase the risk of breast cancer and these mutations are commonly found in individuals with a family history of the disease.
Other gene mutations
Apart from BRCA1 and BRCA2, there are several other gene mutations, such as TP53 and PTEN which have been associated with an increased risk of breast cancer.
Family history of breast cancer
Having a first-degree relative, such as a mother or sister, With a history of breast cancer raises the likelihood of developing the disease.
Hormonal Factors
Early onset of menstruation (menarche)
Girls who get their period early, especially before the age of 12 have a greater lifetime chance of developing breast cancer.
Late onset of menopause
Due to prolonged exposure to estrogen and progesterone, Women who enter menopause later in life have a slightly higher chance of developing breast cancer.
Hormone replacement therapy (HRT)
Breast cancer risk has been linked to long-term usage of hormone replacement treatment particularly estrogen + progestin.
Use of oral contraceptives
While it has been discovered that using oral contraceptives does not affect the chance of developing breast cancer, Some formulations with high doses of estrogen and progesterone may marginally raise the possibility.
High levels of estrogen and progesterone
Elevated levels of these hormones, Either naturally or through medications can contribute to the development of breast cancer.
Lifestyle and Environmental Factors
Sedentary lifestyle and obesity
Being inactive, overweight, or obese can all raise your risk of developing breast cancer.
Alcohol consumption
An increased risk of breast cancer development has been linked to frequent and heavy alcohol use.
Smoking and exposure to tobacco
As potential risk factors for breast cancer smoking and exposure to tobacco smoke have been identified.
Diet and nutrition
Poor dietary decisions, such as consuming a lot of saturated fats and few fruits and vegetables, Can increase the risk of breast cancer.
Environmental toxins and pollution
Exposure to environmental pollutants, Such as pesticides and certain chemicals has been linked to an increased risk of Breast Cancer.
Reproductive Factors
Nulliparity (not giving birth)
A woman’s risk of breast cancer is increased if she has never given birth or if she had her first kid after turning 35.
Late age at first childbirth
Delaying the age of first childbirth, particularly until after the age of 30 may slightly increase the likelihood of breast cancer.
Infertility and fertility treatments
Certain fertility treatments, Like the use of assisted reproductive technologies, have been associated with a slightly elevated risk of breast cancer.
Multiple pregnancies
Women who have had multiple pregnancies, Especially before the age of 30 have a reduced risk of breast cancer.
Breast Density
Definition and measurement
Breast density refers to the proportion of glandular and connective tissue about fatty tissue in the breast, It is often determined through mammography.
Relationship to breast cancer risk
In comparison to women with less thick breasts, Individuals with denser breasts are more likely to get breast cancer.
Implications for screening and diagnosis
Dense breast tissue can make it more challenging to detect breast cancer using mammography alone, Additional imaging methods like ultrasound or magnetic resonance imaging (MRI) may be recommended for women with dense breasts.
Benign Breast Conditions
Fibrocystic changes
Fibrocystic changes in the breast, characterized by the presence of lumps or cysts are common and usually benign. However, Some studies suggest a slightly increased risk of breast cancer in women with fibrocystic changes.
Atypical hyperplasia
Breast cells that exhibit aberrant alterations known as atypical hyperplasia initially seem noncancerous but carry a higher chance of developing into breast cancer.
Radial scar
A radial scar, despite its name, is not a scar but a benign lesion that may increase the risk of developing breast cancer in the future.
Lobular carcinoma in situ (LCIS)
LCIS is a noninvasive condition in which abnormal cells are found within the lobules of the breast, While LCIS itself is not cancer, It is considered a risk factor for the development of invasive breast cancer.
Previous Radiation Therapy
Impact of chest radiation
Women who have undergone radiation therapy to the chest area, Typically as treatment for other cancers during childhood or early adulthood, have an increased risk of breast cancer later in life.
Age at radiation exposure
The risk of developing breast cancer due to previous radiation therapy is influenced by the age at which the treatment was received with higher risks associated with exposure at younger ages.
Socioeconomic Factors
Access to healthcare
Limited access to healthcare, including preventive services and proper screening can hinder early detection and increase the risk of late-stage breast cancer.
Socioeconomic status and education
Lower socioeconomic status and educational attainment are associated with higher breast cancer incidence and poorer outcomes.
Racial and ethnic disparities
Certain racial and ethnic groups experience disparities in breast cancer Diagnosis, Treatment, and survival rates.
Cultural beliefs and practices
Different groups may experience differences in risk and outcomes as a result of cultural beliefs and practices, which may also affect how often people use screening programs and are aware of breast cancer.
Age and Gender
Increasing risk with age
As women become older, Their chance of breast cancer increases, Women over 50 are diagnosed with breast cancer more often than not.
Male breast cancer
Although rare, men can also develop breast cancer typically at an older age.
Other Medical Conditions
Diabetes and insulin resistance
Women with diabetes or insulin resistance may have a slightly increased risk of Breast Cancer.
Autoimmune diseases
Certain autoimmune diseases, Such as lupus and rheumatoid arthritis have been associated with a higher likelihood of developing breast cancer.
History of other types of cancer
Individuals who have previously been diagnosed with certain types of cancer, Like ovarian or endometrial cancer, Have a higher risk of developing breast cancer.
Breastfeeding
Protective effect in reducing breast cancer risk
Longer durations of breastfeeding have been shown to have a protective effect against breast cancer in women.
Duration and exclusivity of breastfeeding
The risk reduction in breast cancer is more significant with prolonged duration and exclusive breastfeeding.
Hormone-disrupting Chemicals
Endocrine disruptors in the environment
Exposure to endocrine-disrupting chemicals, Such as bisphenol A BPA and phthalates, May play a role in increasing breast cancer risk.
Exposure to consumer products
Consumer products, Including certain plastics and cosmetics, May
contain substances that can disrupt hormonal balance and potentially contribute to breast cancer development.
Risks during critical periods of development
Exposure to hormone-disrupting chemicals during crucial periods of breast development, Such as in utero or during puberty may have long-lasting implications for breast cancer risk.
Emotional and Psychological Factors
Chronic stress and anxiety
Prolonged periods of chronic stress and high levels of anxiety have been suggested to affect immune function and potentially increase the risk of breast cancer.
Impact of trauma and emotional well-being
Adverse life events trauma and poor emotional well-being can hurt overall health and potentially influence breast cancer risk.
Preventive Measures
Role of regular self-examinations
Regular self-examinations can help individuals become familiar with their breasts and detect any abnormalities or changes that may require medical attention.
Clinical screenings and mammograms
Routine clinical screenings and mammograms as recommended by healthcare professionals are vital for early detection and can significantly improve outcomes.
Genetic counseling and testing
For risk assessment and decision making people with a family history of breast cancer or certain genetic variables may benefit from genetic counseling and testing.
Lifestyle modifications
Adopting a healthy lifestyle, including regular physical activity balanced nutrition limited alcohol consumption and avoidance of smoking can lower the risk of developing breast cancer.
