Progress in screening and treatment has significantly improved survival rates since 1989, awareness of symptoms and the need for screening are important ways to reduce the risk of disease, breast cancer can affect men as well.
After puberty, the woman’s breasts consist of fat, connective tissue, thousands of lobules, and small glands that produce milk for breastfeeding. When cancer occurs, the cells of the body multiply uncontrollably, causing cancer.
Breast cancer usually begins in the inner lining of the milk ducts or lobules that supply it with milk and can spread to other parts of the body. The exact cause is still unclear, but some risk factors make it more likely.
a) Age where risk increases with age for breast cancer
b) Genetics Genetic factors influence cancer because the disease’s transgenic genes can be inherited.
c) Women who have breast cancer are more likely to be infected again, compared to those who do not have a history of the disease, such as having some benign or non-cancerous species increases the chance of developing cancer later.
d) Exposure to estrogen for a longer period increases the risk of breast cancer.
e) Obesity or postmenopausal obesity in women may have a greater risk of breast cancer, possibly due to elevated levels of estrogen.
f) Radiation therapy increases the risk of breast cancer later in life.
g) Hormone replacement therapy and oral contraceptives increase breast cancer, due to increased levels of estrogen.
