Breast cancer is the commonest of the cancers that affect women. Is the number one killer among the tumors that affect women and the second leading cancer killer of humans in general, after lung cancer, which is an open file of each woman.
Can be summarized as risk factors for breast cancer in the following points:
1 genetics responsible for the limited number of cases of breast cancer (5%) only, the risk of infection of 2 to 3 times at about the women who are patients in their history of family breast cancer for two or more first-degree relative such as mother, sister or grandmother, The risk increases if the injury occurs at an early age, or if the injury is a two-sided from the outset. On the other hand, the presence of other types of cancers in the history of the illness to their families does not mean never increase the risk of breast cancer.
2 research suggested that taking oral contraceptives that contain high levels of estrogen for a longer period than eight years increases the risk of breast cancer among young women (before menopause), and therefore recommends that women currently using contraceptives that contain low levels of estrogen because it is safer in this regard, but on the other hand it protects against ovarian cancer and cancer of the lining of the uterus.
3 Finally, attention turned Baliaadp hormonal treatment (used to relieve the symptoms of menopause or the prevention of heart disease or to treat osteoporosis), a factor that might increase the risk of breast cancer, especially if used these drugs for a longer period than twenty years, and in all cases women have to take into account what can be caused by this treatment of the dangers, especially when there is a familial history of breast cancer.
4 The early menstruation and late menopause increase the risk of breast cancer due to an increase the period during which women exposed to the impact of sex hormones.
5 Breast cancer is more common in women, the rich, and some people think that the reason is to increase growth during childhood is caused by lack of physical activity and overnutrition in that period, showing that obesity increases the risk of breast cancer, especially after menopause. It is advisable to reduce the food contained fat and increase physical activity.
6 induced abortions are associated with slight increase in the risk of breast cancer.
7 studies show that the Japanese women who have been subjected to the atomic explosion and remained alive, and studies that included women who have been subjected to high doses of X-rays (X rays) in the context of medical procedures, that exposure to ionizing radiation increases the risk of breast cancer, and accelerate the development. The impact is carcinogenic radiation is stronger if the exposure occurred at the age between 10 to 20 years, with developing breast tissue during this period is very fast, and the risk is less if the exposure before the age of 10 years or after the age of 40 years.
Apart from sporadic reports that indicated a relationship between breast cancer incidence and consumption of caffeine (coffee), it has failed the vast majority of studies conducted in the investigation of any relationship between them.
Some studies have shown that smoking and the protective effect of low incidence of breast cancer, but other studies have found a causal relationship between them is weak, and the outcome can be summarized that most of the studies failed to find a causal relationship between smoking and breast cancer.
The same story applies to exposure to multiple factors suspected in the beginning of a relationship between them and get breast cancer, and detailed studies failed to demonstrate this relationship and these factors (hair dyes, and Akakiralersrbin, diazepam).
Also, the limited evidence suggests a positive relationship between mental stress and inactivity and for breast cancer. On the other hand did not prove to date and a relationship between breast cancer incidence and exposure to magnetic fields from power transmission lines (electrical).
And Qaiyat
Just as it listed the risk factors, protective factors can be summarized as follows:
1 to breastfeed parental protective effect of breast cancer, the greater the number of months of breastfeeding decreased the risk of breast cancer.
2 showed that the early pregnancy protective effect of breast cancer, and I think that this is due to the impact induced to increase the differentiation of breast cells, which limits the ability of the cell from abnormal growth and reduce the impact of carcinogenic factors later.
3 The increase in the number of births in women reduces the risk of breast cancer. Illustrate this problem, particularly in developed countries where women postpone pregnancy and Iqlln the number of children for reasons of study or professional, which leads to increased rates of breast cancer in the future. For example, is expected to increase the incidence of breast cancer in the United States about 5 approximately 10% over the past 52 years.
4 have to deal with fresh vegetables and fruits a protective effect of breast cancer.
5 In two studies found that moderate physical activity reduces the incidence of breast cancer in women, but this relationship needs confirmation from larger studies. May affect physical activity through its impact on hormones of the Interior. Where one of the studies confirm that moderate physical activity at an early age decreases the frequency of sessions Ibaadis in women, another study suggests that moderate physical activity in the Sunni Alif reduces the levels of the hormone progesterone.
It was for the early detection of breast cancer were largely due to improved warning and prolong the life span and that gave us a greater opportunity to fight and cure, so we finally went all the recommendations to the importance of educating women and their access to adequate information on breast cancer and the need to monitor continuously by following the Breast Screening Program, which includes:
1 a survey of both breasts Balmamujram, a depiction of the breast tissue X (X) one that uses very low doses of Atsie public health of the body, and when the vote is pressing the breast tissue and installs between sheets of plastic and this annoying when some women, but the rays take less than a minute. This picture shows the changes in the breast tissue is very careful to note before visual contact. It is necessary to undertake the survey between the ages of 35 40 years to get the so-called basic Balmamujam I compare it all the pictures later conducted to detect any change no matter how small can occur to the breast tissue, as recommended commissioned annually after the age of 50 years.
2 clinical breast examination by a specialist, and are advised commissioned periodically every three years in women aged 20 to 40 years, and every year when women over 40 years.
3 provide guidance for the conduct of breast self-examination is recommended, which commissioned a month after reaching twenty years, it is important for each woman first distinguish the natural form of natural and cyclical changes that occur on the breast, such as tension, Ilam, pre-menopausal breast or during pregnancy so you can see the changes of non-natural possible changes in the breast, and the best time for self-examination is in the showers, where women stand in front of the mirror and lifted her arm up and prove her side behind the head and examines breast Bjsh flat surface of the forefinger and middle (not pressure heads fingers) from the top down so check with the landing armpit .
The most important changes you should notice are:
The emergence of a node in the breast or armpit, or any thickness in the region.
The emergence of protrusion or pleated or withdrawal on the skin of the breast.
The emergence of a change in the form of a nipple (such as Gwor nipple), or a change in skin color.
The emergence of Ceylon or abnormal secretions (runny blood ..) of the nipple.
When you notice any of these changes described should see a doctor competent to obtain accurate diagnosis and testing required.
