Breast Cancer Screening

One in 9 women is expected to develop breast cancer during her lifetime. One in 27 will die of it. Breast cancer attacks mainly women, however there?s 1% of breast cancer patients are men.

Screening tests cannot be employed in all diseases. In some cases a useful screening test may not be available, and in some other cases it may not be worth screening for a disease because screening and finding out the disease early may not change the natural history of disease. The later is probably true in case of screening of lung cancer. From the studies so far published, there is no clear evidence to suggest that screening for lung cancer in high-risk population (smokers)

Other risks of mammography include the radiation that each breast is exposed to during a mammogram. During a chest X-ray, a person receives 1/1000 of a RAD, or radiation absorbed dose. This type of X-ray is a high energy X-ray. During a mammogram, however, the X-ray used is a low energy X-ray and results in 1 RAD or a 1000-fold greater exposure than a simple chest X-ray. It has been suggested that the low energy X-ray used may cause greater biological damage which is cumulative over time. In a journal entitled Radiation Research and published in 2004, the author concludes that the risks associated with mammography screening may be FIVE times higher than previously assumed and the risk-benefit relationship of mammography exposures need to be re-examined.

Recommendations for breast cancer screening vary from country to country and within the same country according to the views of different organizations who recommend the screening. American Cancer Society recommends that "women age 40 and older should have a screening mammogram every year and should continue to do so for as long as they are in good health."

Starting from age 20, women may choose to do breast self-examination. The benefits of BSE may not be too obvious as it?s probably a little too late when you can notice any changes. It could still be beneficial in that it helps notice any changes in the breasts so you can report them to your doctor.

Since mammogram uses X-rays, there may be slight risk associated with exposure to radiation in women who get mammograms. However the amount of radiation associated with mammogram examination is very small and is strictly controlled by regulatory agencies like National Department of Health and Human Services. Very strict regulations are enforced by this agency to make sure that mammography equipment is safe and uses the lowest dose of radiation possible. The dose of radiation used by the modern mammogram machines does not significantly increase the risk of breast cancer.

Self-breast examination as the name implies denotes examination of breast by women, without the help of a physician. This can be undertaken in the privacy of their home. Probably the best time to do a self-breast examination is while taking showers. Women can ask their physicians to teach them the technique of self-breast examination. American Cancer Society recommends "women in 20s and 30s should have a clinical breast examination (CBE) as part of a periodic (regular) health exam by a health professional preferably every 3 years. After age 40, women should have a breast exam by a health professional every year." Regarding self-breast examination, American Cancer Society gives the following recommendations: "BSE is an option for women starting in their 20s. Women should be told about the benefits and limitations of BSE. Women should report any breast changes to their health professional right away."
