Women have more problems in their bodies than men, and for this reason, military service is not considered for women. The second most common cancer among women is breast cancer, which most people do not know about its causes. Here are 5 cases. We have mentioned that if you do not follow them, you will get breast cancer.
Although many people know that the biggest risk of breast cancer is high-risk factors such as obesity and having a family history of this disease, many are not aware of the causes and other high-risk behaviors. In the following, the cases that increase the risk of contracting this disease are mentioned.
1– alcoholic drinksDrinking alcohol is associated with an increased risk of breast cancer. According to the American Cancer Society, women who drink alcohol daily are 1.5% more likely to develop breast cancer than women who do not drink alcohol at all. According to researchers, alcohol changes the way estrogen is metabolized in women’s bodies, and as a result, the amount of estrogen in the blood increases. High level of estrogen is the main cause of breast cancer. 2– Pregnancy at an advanced age (or not having children)According to the American Cancer Society, pregnancy after the age of 30 or not having children at all can increase the risk of breast cancer in women. According to the National Cancer Institute, pregnancy reduces the monthly cycle of women throughout their lives, as a result, the accumulation of estrogen in the body decreases. The risk of breast cancer in women who have one child increases with age. In addition, the more children a woman has, the lower the risk of breast cancer. 3- Not breastfeeding the babyThe relationship between breastfeeding a baby and breast cancer is not very clear, but according to researchers, breastfeeding a baby reduces the risk of breast cancer to some extent. According to the American Cancer Society, the longer a baby is breastfed, the lower the risk of breast cancer. Again, the increase of this risk is due to the amount of estrogen in the body of women. 4- Contraceptive pillsOral contraceptive pills are safe to some extent, but some types have been found to increase the risk of breast cancer in women. According to the American Cancer Society, injectable progesterone, which is injected every 3 months, increases the risk of breast cancer. In addition, studies have shown that women who take oral contraceptives have a slightly increased risk of breast cancer compared to women who have never taken the pill. 5- Night shift workResearch shows that night shift work is associated with an increased risk of breast cancer in women. It seems that this increased risk is caused by hormones. According to the researchers, this effect is caused by changes in the amount of the hormone melatonin, a hormone that is affected by the body’s exposure to light. Researchers say that normal levels of melatonin at night are important for regulating the number of natural hormones, including estrogen.
