Age And Physical Risk Factors In Breast Cancer
The age factor is probably the overall most important associated risk of breast cancer. Increases the risk of breast cancer in older postmenopausal population. For this reason, all screening recommendations for breast cancer are based primarily on age. Obesity may be the single most important and most preventable risk associated with breast cancer. With the dramatic increase in obesity in the United States, this may be the main reason for the continued high incidence of breast cancer. Other physical factors also play a role in the risk of breast cancer. These include the size, body shape, breast, mammography, and density. These physical factors are summarized below.
Body weight and breast cancer: a woman's weight affects the risk of breast cancer, but the effect is different for breast cancer before menopause and menopause. Most studies have shown that women heavier (weighing over 175 pounds) have a lower risk of breast cancer before menopause and increased risk of breast cancer after menopause compared to women thinner (d ' Weighing less than 130 pounds). Given that 80% of breast cancers occur after menopause, the negative impact of obesity far outweigh the benefits. The results are the same regardless of body weight is examined directly, or body mass index used to correct the effects of altitude on body weight.
Body shape and breast cancer: Several studies in humans have shown that women who bear more than their body fat in the abdomen (apple shaped) have a higher incidence of breast cancer after menopause that women with more fat around their hips (pear shaped). This seems to be true regardless of body weight women. The relationship was fat on the body and the risk of breast cancer before menopause has not been clearly established
Height and breast cancer: the height of a woman was associated with risk of breast cancer in numerous studies. Taller women (5 "9" or above) is a small increased risk of cancer in both premenopausal and postmenopausal women within that short (5 '3 "or shorter). Height of a person is determined by the interaction between genetics and nutrition. How high can affect the risk of breast cancer is unclear.
Breast and breast cancer: It is a popular belief that small breasts are less likely to have breast cancer. This theory has been used to explain why women with breast implants have a lower risk of breast cancer. However, most studies found no link between breastfeeding and risk of breast cancer. A study has been able to find an increased risk of breast cancer in women with thin breasts bigger. In this study, were more than 4,000 women for their bra size before birth. Women who were lean (lower chest to 34 inches) and had larger breasts (size, B, C or more cups) were at increased risk of breast cancer after menopause compared to women with breast A or smaller cup. Women with breast size was no relationship between the size of the breast cup and risk of breast cancer. Further studies are needed to confirm these results
Mammography equipment Density: Several epidemiological studies have shown that breast density measured on mammography is a major risk factor for breast cancer. The risk of breast cancer associated with the highest category of density was estimated to be much higher than in the lowest category density. Mammogram density material appears to be a predictor of developing invasive cancer after DCIS (ductal carcinoma in situ). Increased density is associated with an increased risk of breast cancer among premenopausal and postmenopausal women with both the effect of being within ten years after the mammogram. Mammogram density material has also been shown to be a risk factor for breast cancer among women with a family history of disease. Mammogram density of material is probably also important in patients who are BRCA positive. In fact, the density of mammography equipment actually an important hereditary component.
