The answer is still uncertain. A team of researchers at the Institute of Cancer Research in London tracked 160,900 women for an average of 11 years. The participants were divided into two groups: Women each morning study group were offered annual mammography screenings beginning at age 40, while those in the control group were offered annual screenings beginning at age 50.

Deaths resulting from breast cancer among the younger women decreased by only 17 percent, a figure considered by researchers to be not statistically significant. However, the study also found that in this group of women 23 percent had at least one false-positive result, as opposed to 12 percent of older women. (A false-positive result is an irregularity in the screening process that later turns out not to be breast cancer.)

Regular screening also increases the likelihood of radiation-induced breast cancer, a risk quite a few endocrinologists believe outweighs the benefit in a tiny percentage of lady.

The researchers figured annual mammography screenings remain too uncertain to conclude certain net benefit accrues to women within below 50 age-group. Another study conducted by researchers at France's National Institute of Health and Medical Research (Institut National de la Sante et de la Recherche Medicale, or INSERM), found out that chest X-rays may just raise the potential for breast cancer in ladies with the breast cancers gene mutations BRCA1 or BRCA2.

Researchers studied 1,601 European and Canadian women with the BRCA1 or BRCA2 gene mutations, which greatly increase possible breast and ovarian cancers. The group included 853 women with breast cancer.

The results show the women who reported having chest X-rays were 54% more likely to have built breast cancer, equated with those who reported having no chest X-rays. That outcome was more prevalent among women up to 40 years old and those who reported having had chest X-rays before age 20.

According to the Susan G. Komen Breast Cancer Foundation's web site, the BRCA1 and BRCA2 gene mutations are carried by close to 250,000 women inside of U.S. These inherited gene mutations be the reason for 5 to 10 % of breast cancers diagnosed in the U.S. A woman's odds of developing breast cancer, assuming that she lives towards age of 85, are about 13 percent if he has no BRCA2 mutation, 60 to 80 percent if a woman has a BRCA1 mutation, and 30 to 85 percent if she is sufffering from a BRCA2 mutation.

It is known that radiation exposure can increase risking potential cancer. However, it must be noted that X-rays typically use 'abnormal' amounts of radiation that are generally considered safe. It is also known that the younger the age at first exposure to radiation the greater the danger of breast cancer.

The timing of exposure can be as important for the reason that dose. When exposure occurs during time of greater cell growth of the breast, vulnerability to your cancer-causing effects of radiation is inflated. Even in older women who are nevertheless having a menstrual cycle, the timing of exposure is very important. The cumulative dose like annual mammography screenings starting below age of 40 in a female with the breast cancers gene mutations BRCA1 or BRCA2 significantly increases the complication.

Breast cancer takes years to develop from the first genetic event or exposure to the when a lump is seen on the mammogram or felt during a breast exam. It may happen that the initial genetic damage may have occurred very at the beginning of life. It is difficult to pinpoint when the initiating event took place.

Although the medical establishment takes to avoid exposing a woman who might be pregnant to X-rays, a woman should also avoid having a mammography screening at the end of a period because that's the time when the breast cells are reproducing most rapidly.

Since young women and women who are genetically at high-risk for breast cancer are more affected by X-ray radiation, being exposed to radiation should be limited and alternatives should be working at emergencies. Magnetic resonance imaging (MRI), which uses imaging technology dissimilar to X-rays, could include a good alternative to X-rays and mammography.

It may be the responsibility each woman determine for herself (after research) whether she should risk developing breast cancers as an effect of routine mammography screenings or risk having the complications of late-diagnosed cancer of the breast that might have been avoided if detected earlier by screening mammography.
