Girls with big breasts are more likely to provoke breast cancer? I'm afraid there is a misunderstanding, these factors are the key
When girls enter puberty, under the influence of endogenous hormone secretion, various organs of the body will begin to develop rapidly. For example, menarche is a typical manifestation of development. In addition, the chest will gradually become larger!
For young girls who are sensitive during puberty, the most fearful thing is breast development, and they are worried about seeing other people's strange eyes. But when I grow up, looking at the empty "airport", some can't help but envy women with perfect bodies, and even faintly have the idea of breast augmentation!
However, in recent years, there have been many rumors about "big breasted girls" being unhealthy, and there are even rumors that women with bigger breasts are more likely to develop breast cancer later on! Is there really any scientific basis for this?
The reason why there are such rumors is because some people think that large breasts are the result of estrogen secretion, and abnormal estrogen secretion is the murderer of breast cancer, so people with large breasts are more likely to develop cancer!
Although abnormal fluctuations of hormones in women may indeed be related to the incidence of breast cancer, because abnormal secretion of hormones can stimulate changes in breast epithelial tissue and cell mutation, especially in the case of abuse of estrogen and irregular life, it will lead to women. Endocrine disorders!
However, if it is said that too large breasts will increase the incidence of breast cancer, it does not stand firm! Because breast size or not, the key to the decision is not the breast. The glands, duct structure, and number are the same in your breasts, whether you're an airport or a strong double-humped body. What really determines breast size is actually fat, which is why fat mm has more plump breasts!
The real reasons related to breast cancer are actually the following:
- Inheritance: Breast cancer is a type of cancer with a clear genetic predisposition. If the mother develops breast cancer in both breasts before menopause, the probability of passing it on to her daughter is relatively high, or even more than 3 times. . If you have two close relatives with breast cancer, your risk of developing breast cancer will increase by as much as 7 times;
Obesity: Obesity is also one of the causative factors of breast cancer. It is not obesity that directly causes breast cancer, but because most of the obese people have problems such as irregular diet and sedentary, long-term sedentary will reduce the body Immunity, and long-term intake of fatty foods, steroids in fat will be converted into estrogen in the body, a large amount of estrogen accumulation in the body, can cause endocrine disorders, stimulate the breast, increase the appearance of cancer and pathological hyperplasia probability;
Life is too disordered: If women have bad habits such as smoking and lack of sleep for a long time, or if they have too much pressure in life, or have a bad temper, it is easy to cause endocrine disorders. When the secretion of estrogen is disturbed, estrone and estradiol will stimulate the mammary glands, resulting in changes in the epithelial cells of the mammary glands. The more women who live in disorder for a long time, the greater the possibility of breast disease;
DINK, no history of breastfeeding: If a woman has never given birth, or for various reasons after giving birth, she did not breastfeed, which may also increase the risk of breast cancer. This is because breastfeeding involves two biological mechanisms in the human body, which can not only terminate the differentiation of the mammary gland epithelium, but also prolong the recovery of the menstrual period after pregnancy and reduce the stimulation of the breast by endogenous hormones. Therefore, women with a history of breastfeeding are more likely to develop breast cancer also relatively low;
Women who have had multiple abortions: When the fertilized egg begins to implant and develop, the hormones in the body will quickly adjust, the level of estrogen and progesterone will increase significantly, and prolactin will also begin to secrete, and the mammary ducts and acinars will all enter into development. Expanded state, ready for breastfeeding.
If the pregnancy is terminated suddenly, the secretion of chorionic gonadotropin will decrease suddenly, resulting in endocrine disorders, and the mammary glands will not be easy to return to the original state, and pathological breast hyperplasia is prone to occur. Moreover, when the hormone fluctuates, it will also stimulate the breast.
In general, big-breasted girls don't have to worry at all. Big breasts are not the reason for breast cancer. In hot summer, let's show off your perfect figure! The above factors may become the killer of breast cancer. In addition, female friends should pay attention to breast changes in life. If you find that there is a painless, irregular lump in the breast, it is better to actively seek medical examination.
