There are many risk factors, which one can breast cancer in women, and the life time incidence rate of breast cancer is 1 in 8. This means for every 8 women, you know, develop this type of cancer in your life one of you. So are we do, this help what causes that breast cancer, and what happened?
Breast cancer occurs when within of breast tissue in a way the uncontrolled growth and destruction allows certain cells parts of the surrounding tissues; the cancer cell can then spread, where you grow the lymph glands and other organs in the same destructive manner. This growth is not the normal growth, which is necessary to the function of the part of the body which it grows, in this case of breast tissue. Researchers continue to look at, which may affect the incidence of breast cancer for the various factors. You feel that something happens primarily on the DNA or gene of cells, which causes the factors the growth affected will usually control. This could be a genetic mutation, that of a woman with born is it can age, exposure to radiation in younger years, or a variety of other lifestyle topics.
There are many causes for breast cancer, but a risk factor has been increased and is somewhat disputed by obesity is. There are statistics of research centres, suggesting that the breast cancer can be prevented 25-30%, by having a lean body mass. Epidemiologists note that the incidence of this type of cancer is increasing, but you speculate that our genes, essentially the same in the last decades many have been.
What are so fat with breast cancer? The fat cells that develop later in life are so that generally for storing estrogen, fat, that there are more estrogen, which the breast tissue is exposed to. As estrogen will result in many breast cancers fuels, this may be increased risk, which some researchers up to 60% one. It is recommended by the American Cancer Society to get involved, to reduce the risk of cancer in 30 minutes of exercise 5 days a week. It is also recommended that even lean women work muscle mass increased still in maintenance, to reduce, the creation of new fat cells. As already mentioned, this risk factor is felt, controversial and not easy to prove. However, it was noted that the risk of breast cancer when later in life and in recent years is increased seems. This may be partly due to the fact that weight gain in the menopause is years often visceral fat which is hormonally active as subcutaneous fat.
What are the other risk factors for breast cancer?
1. Gender-his female means increased estrogen of amounts of on growth of cells in breast tissue.
2. Old 2/3 s breast cancer is by age 55; 1 / 8 of breast cancers occur under the age of 45. Old effects the gene, which is our body function to regulate and the older, a person, the more likely, the an error in the genetic code is running.
3. Genetic factors many women believe that no one would have in your family breast cancer hasn't, you likely that there are. Genetic mutations such as BRCA1 and BRCA2 genes account for 5% to 10% of cases of inherited.
4. Family history with a first-degree relative (mother, sister, daughter) with breast cancer doubled the risk of developing this form of cancer. It is believed that 20-30% of women with breast cancer have a family history.
5. History of breast cancer - increased this a second cancer risk rather than a repetition of 3 - 4 times.
6. Race and ethnicity it of breast cancer in white women of the African American women are a slightly higher rate but African American women are more likely to die, as they tend to get more aggressive types of breast cancer from their cancer. Asian, Hispanic and Native American women have a lower incidence and risk of dying from breast cancer.
7. Dense breast tissue make screening harder, there is more glandular tissue and less fat.
8. Beginning of menstruation before the age of 12 and menopause after 55 increases risk of breast tissue exposed to more hormonal cycles. For this same reason, no children or children to 30 and few years breast feeding also more estrogen and progesterone mean exposure to breast tissue which in turn, risk.
9. Previous chest radiation for other conditions such as lymphoma and certain types of cancer that can occur at a young age.
(10) DES women had DES during pregnancy and their daughters in utero at this time are higher risk of breast cancer with mutations of genes.
There is some life style issues that are felt to affect the risk of cancer in the breast tissue. There is a slight increase of the vulnerability of women, which on oral contraceptives for a few years have been, although this risk is reduced when the OCP is suspended, and after the decline continues.
Combined HRT was proven in studies to increase the risk of cancer in breast tissue in less than 2 years of use. This risk is somewhat attenuated, alone, used estrogen without progesterone.
Use of more than 7 drinks a week can also increase risk for breast cancer, this risk can be as much as 1 ? times normal, if consumed 2-5 drinks per day on a regular basis.
After one or more of the above risk factors does not mean that a woman get breast cancer, it merely reflects risk may be higher. Life style changes can help to reduce these risks. In many cases the diagnosis can be made early cancer, treatments have come a long way and are very effective. It remains exciting research new factors affect that occur and the growth of breast cancer, which opens up new therapies and can to discover.
Each type of cancer can risk factors and an unhealthy lifestyle, hopefully the above information helps you to reduce the risk of cancer, in you breasts. There are also many other benefits for the health of a healthy lifestyle, not just cancer. Health of the heart and bone health are also reached with a healthy diet, movement, avoiding cigarette smoke and alcohol limit. It is not only our genes, it is also what we do, these genes.
