We will tell you about possible risks and causes of Breast cancer. You can find information about:
Like other cancers, your risk of breast cancer increases as your age, that's why most patients diagnosed with breast cancer over 50 years old. This is because as the growth of the age, The cells in our bodies tend to make more mistakes (DNA replication error) when the cells were dividing, therefore, it causes cancer.
Family history of breast cancer
Breast cancer have a family genetic predisposition, epidemiological survey found that 5% to 10% of breast cancer are familial. If one member of the immediate family has breast cancer, the risk of breast cancer increased by around 1.5 ~ 3 times; If two member of the immediate family have breast cancer, the risk of breast cancer increased by around 7 ~ 8 times. The younger the age of onset, the greater the risk of breast cancer among relatives.
Earlier menarche or late menopause:
The women with earlier menarche (before the age of 12) or late menopause (after the age of 55) had higher risks of breast cancers. Because the time of estrogen action is too long, easily lead to breast cancer.
Nullipara, Late childbirth, Do not breastfeed:
The incidence of breast cancer in nonparous women or women who have not given birth until 35 is higher than those who give birth before the age of 30. One of the most clearly defined risk factors for breast cancer determined by the medical community is nonparous women because they lack the protection of progesterone and are more vulnerable to the stimulation of excessive estrogen. Besides, breast-feeding can decrease the risk of breast cancer in women, and the longer the time of women's breast-feeding is, the smaller the risk of breast cancer in them will be in the future.
Smoking and Drinking
Smoking and Drinking have an increased risk of developing breast cancer. The risk of developing breast cancer increases with the number of cigarettes smoked and quantity of alcohol intake. You should be determined to quit smoking. In women, the intake of alcohol should not exceed 2-3 units per day,
Eating too much fat
Your diet may affect your risk of breast cancer, women who eat a lot of fat in their diet have a greater risk of breast cancer than than women with low fat diet. We recommend that 20% to 30% of daily calories comes from fat. In other words, the amount of calories provided by fat does not exceed 30% of the total calories in your diet. Eat more fruits and vegetables, eat less fried foods, butter, fat meat and so on.
Overweight and Obesity
The overweight and obesity can increases your risk of breast cancer. Studies show that the risk of breast cancer in obese individuals is 1-1.5 times that in those with normal weight and that the risk of metastasis of breast cancer is twice as high as that in the latter. If the post-menopausal women are overweight or obese, their risk of breast cancer will be increased by 30%.
You can use BMI to determine whether you are overweight or obese.
Faulty Gene: BRCA1/BRCA2
If you have an obvious family history of breast cancer, you may carry the BRCA1/BRCA2 gene, these genes can increase your risk of breast cancer, the prevalence rate of breast cancer was higher than population without these genes. Studies have shown that about 60-70% of people with the BRCA1 and BRCA2 gene will develop breast cancer.
People suffering from other cancer
If you have been diagnosed with other cancer (Include hodgkin lymphoma, lung cancer, womb cancer, bowel cancer, LCIS, DCIS and melanoma skin cancer), your risk for the breast cancer may be increased.
Hormone replacement therapy
Hormone replacement therapy is also called HRT, the HRT can release the symptoms caused by menopause, such as have a pain in the head and back, hot flashes, osteoporosis, high blood pressure and so on. However studies show that prolonged use of the HRT may increase your risk of developing breast cancer, but the ratio of breast cancer is not high, just about 2-3 out of 100 breast cancers in women were linked to long-term use of HRT, you don't need to worry too much about it, talk with your doctor and counselor about the benefits and risks of HRT in your individual situation.
Such as hyperplasia of breast, chronic mastitis cysts and so on. especially atypical hyperplasia of breast. If you do not treat these diseases in time, they have an increased risk of developing breast cancer.
Birth control pills
Because Birth control pills containing estrogen. Estrogen can stimulate breast cancer cell growth. in theory, taking the extra estrogen may increases your risk of breast cancer. However, it is discovered that the drug increases the risk of breast cancer is very small. In addition birth control pills can reduce the risk of ovarian and uterine cancer. But for female who have an obvious family history of breast cancer, Birth control pills may significantly increase your risk of developing breast cancer, these female can also use condom instead of pills.
As observed by statistical data, white women have a greater risk of breast cancer than do women of other races, but the reason is not entirely clear, this difference may be associated with different living habits.
Women with dense breast tissue
Breast tissue is made up of fat and connective tissue. Some women with more breast fat and less breast cells, while other women's breast glands are dense, their breast tissue have more connective tissue and more breast cells. Dense breast tissue is very common, about 40% of women's breasts are like this. Because the risk of developing breast cancer increases with the number of breast cells, so these women
have a greater risk of breast cells than women with the lowest density (About five times). For women with dense breast tissue B ultrasound and MRI examination is more suitable.
Either great radiation accident or nuclear weapon explosion would produce a large amount of radioactive (such as gamma-ray, neutron ray ), which will increases your risk of breast cancer. Medical radiation, such as X-rays, chest X-rays, CT scan, radiotherapy and so on, these rays are very low radiation dose rate, and your doctors keep medical exposure to radiation as low as possible, this may slightly raise the risk. If you worry too much about you had a lot of X-rays, Chest CT and radiotherapy for chest in the past, you can talk to your doctor about it.
Very tall women have an increased risk of developing breast cancer after the menopause. Because tall women have larger body sizes so that their breasts are bigger and contain more breast tissue, which may increase your risk of developing breast cancer.
Women with Benign thyroid conditions
If you have been diagnosed with diabetes, your risk for the breast cancer may be small increased.
It's often hard to say exactly why diabetes may increase your risk of developing breast cancer.
One study showed that post menopausal diabetic women who take metformin have a lower risk of breast cancer than women who did not take the drug.
Anti hypertensive (high blood pressure) drugs
Anti hypertensive drugs may increase your risk of developing breast cancer, If you take antihypertensive drugs for more than five years, which can increase the risk of breast cancer by 20%.
Women who often stay up late
Women who sleep by day and work by night have an slight increased risk of developing breast cancer. Besides lack of sleep may increase your risk of developing breast cancer. Therefore You should develop a good life habit.
Feeling stressed or mood depression:
Young urban women are faced with intense competitive pressure, and their minds are in the state of tension for a long time, leading to emotional instability. Besides, they often stay up late for working overtime,and thus their bodies can not get enough rest. Such an unhealthy lifestyle will lead to the endocrine imbalance and do some damage to their breasts, thereby increasing the risk of breast cancer.
Women with asymmetric breasts
A study shows that women who have one breast larger than the other have a slightly risk of breast cancer than women with symmetric breasts. But the study is the lack of clinical statistics data to support, so the risk cannot be monitored or assessed. For most women, it is normal to have slightly asymmetric breasts, but if you have obviously asymmetric breasts, you should pay more attention to your breast shape and size change.
Women with breast implants
There is no evidence that the breast implants can may increase your risk of developing breast cancer. But the breast implant may affect breast X ray examination, this may require increased X light dose for examining the breast tissue more completely. Theoretically, the more dose of X rays may slightly increase your risk of developing breast cancer, you needn't worry about it unless you have a higher risk of breast cancer.
Long-term use of antibiotic
The study found that long-term use of antibiotic may may slightly increase your risk of developing breast cancer. But another study shows that the use of antibiotics is not a factor in causing the breast cancer. We need to do more research in the relationship between antibiotic and breast cancer. Generally speaking, it is safe to many bacterial infections can be treated with antibiotics, but you should avoid abusing antibiotics.
Pesticide residues on foods
Some research workers found that the pesticide (such as PCBs) residues on foods may have an increased risk of developing breast cancer. However,some studies suggested that typical dietary exposure to pesticide residues in foods poses small risks to breast health or even can be ignored. More research is needed to better define the effects of pesticide residues on breast cancer. If you are at higher risk of breast cancer or you're worried about pesticide residues, eating organic food is a good choice.
