Breast cancer is one of the most common malignant tumors in a woman’s life. You may be surprised, but not only women suffer from this health problem. Even without a breast duct, 1% of men develop breast cancer.
Although medicine has made great progress, it is unclear why some breast cells start to grow out of control. Cancer cells become immortal and tend to grow rapidly, forming tumors. Sometimes they have the ability to spread (metastasize) to lymph nodes, nearby tissues and distant bodies.
You may have heard popular myths that claim that taking dairy products and caffeine may increase the risk of breast cancer. Another common misconception is that the use of mobile phones and microwave ovens is related to the occurrence of cancer. But research has not proven this assumption.
Scientists say that about 5-10% of breast cancer cases are closely related to genetic mutations in BRCA1 or BRCA2 genes. According to statistics, those who started before the age of 12 were more likely to develop breast malignancies. The same happens to women, who enter menopause during menopause.
Although we cannot change the genes and family history, it is entirely possible to modify certain factors, which does increase your risk of breast cancer:
#1. Exposure to radiation
Radiation therapy prescribed for other types of cancer may trigger the growth and division of malignant cells in the breast.
#2. Misusing alcohol
The study shows that regular alcohol consumption increases the risk of breast cancer.
#3. Hormonal therapy
Taking hormone replacement therapy to relieve menopausal symptoms may increase the risk of breast cancer.
#4. Conceiving first after the age 30
Experts say that women who give birth to their first child at an advanced age are at high risk for breast cancer.
#5. Never carrying pregnancy
Studies have found that women who are not pregnant in their lifetime are more likely to develop breast cancer than women who are pregnant at least once.
Exposure to carcinogenic chemicals may be a major risk factor for certain cancers. A study also showed that night shift workers are more likely to develop breast cancer.
