Methods of detecting Breast
Cancer
Mammography High-quality mammography is the most effective technology presently available for breast cancer screening. . Breast Biopsy A breast biopsy or Fine needle aspiration is the removal of cells, tissue or fluid to be looked at under a microscope to check for signs of disease. Ultrasound Ultrasound, also called sonography, is an imaging technique in which high-frequency sound waves that cannot be heard by humans are bounced off tissues and internal organs. Their echoes produce a picture called a sonogram. Ultrasound imaging of the breast is used to distinguish between solid tumors and fluid-filled cysts. Ultrasound can also be used to evaluate lumps that are hard to see on a mammogram. Digital Mammography Digital mammography is a technique for recording x-ray images in computer code instead of on x-ray film, as with conventional mammography. The images are displayed on a computer monitor and can be enhanced (lightened or darkened) before they are printed on film. Images can also be manipulated; the radiologist (a doctor who specializes in creating and interpreting pictures of areas inside the body) can magnify or zoom in on an area MRI In magnetic resonance imaging (MRI), a magnet linked to a computer creates detailed pictures of areas inside the body without the use of radiation. Each MRI produces hundreds of images of the breast from side-to-side, top-to-bottom, and front-to-back. The images are then interpreted by a radiologist. PET The positron emission tomography (PET) scan creates computerized images of chemical changes that take place in tissue. The patient is given an injection of a substance that consists of a combination of a sugar and a small amount of radioactive material. The radioactive sugar can help in locating a tumor, because cancer cells take up or absorb sugar faster than other tissues in the body. Electrical Impedance Scanning Different types of tissue have different electrical impedance levels (electrical impedance is a measurement of how fast electricity travels through a given material). Some types of tissue have high electrical impedance, while others have low electrical impedance. Breast tissue that is cancerous has a much lower electrical impedance (conducts electricity much better) than normal breast tissue. Electrical impedance scanning devices are used along with conventional mammography to detect breast cancer Ductal Lavage Ductal lavage is an investigational technique for collecting samples of cells from breast ducts for analysis under a microscope. A saline (salt water) solution is introduced into a milk duct through a catheter (a thin, flexible tube) that is inserted into the opening of the duct on the surface of the nipple. Fluid, which contains cells from the duct, is withdrawn through the catheter. The cells are checked under a microscope to identify changes that may indicate cancer or changes that may increase the risk for breast cancer Self Examination Self Examination should be done monthly 7 to 10 days from the first day of your cycle. It should be done on the same day of every month if you are not menstruating. |
Watch, Fight and Pray: This book
provides a powerful message that prayer changes things. Dr. Lonnell
Johnson's personal testimony provides a unique strategy of how faith,
prayer along with our Prostate Cancer Protocol allowed him to defeat prostate
cancer.
Surviving Prostate Cancer without
Surgery "Surviving Prostate Cancer Without
Surgery" by Bradley Hennenfent, M.D. (Roseville Books, 2005), begins with the
shooting of a urologist and includes a WWII Battle. Men, and the women who love
them, who want to avoid impotence and incontinence while beating prostate
cancer, will adore "Surviving Prostate Cancer Without Surgery", which reads like
a novel and exposes the big lie.
