Other complications that result from this cancer and others are on top of the clogging and cramming of the system, the body's need to not only supply for itself, but for the large tumors (ACS. All about Breast Cancer). Although there are many different types of breast cancer, these are the most common. The first one is adenocarcinoma. It starts in the glandular tissues in any part of the body. Even though that it is a commonly diagnosed cancer, the prognosis can vary greatly due to when the cancer found. This accounts for nearly all breast cancer. Ductal carcinoma in situ (DCIS) is a noninvasive breast cancer. It starts in ducts but doesn’t spread through the duct walls. The best way to detect this kind of cancer is by a mammogram. This may change into an invasive cancer if not caught in time. If it changes then it called an infiltrating ductal carcinoma (IDC). This form of invasive cancer invades the fatty tissue of the breast. IDC invades to other parts of the body through the lymphatic system and bloodstream. When the cancer name has in situ in it that means, the cancer is localized and has not spread to any other part of the body. Prevention is one part of the puzzle to cure breast cancer, but it is extremely important to get breast examinations often to make sure of no lumps or early tumors. The simplest forms of breast exam are self-examination, one with a doctor, or a mammogram. A mammogram is simply an X-ray of the breast. Mammography can pick up small legions of under one-half of a centimeter, whereas one can’t feel a lump until it is a full centimeter in diameter. Dr. Gardner, a member of national breast cancer researcher in Bethesda, MD says, “Fortunately, because of the use of mammography, we are detecting many tumors before they have a chance to invade the surrounding tissue.” In addition, he said, “Any woman 40 or older should be having a yearly mammogram, but, if breasts are small or dense, a mammogram might not pick it up. Another procedure could be wire localization. A thin wire is used to show where the legion is after the wire is inserted, and local anesthetic is administered.” Thermograph is based on the idea that cancer gives off more heat than regular cells. Tran illumination founded in the concept that light shines through breast tissue but lumps block it. An ultrasound is when high frequency sound waves are sent off in a radar fashion, and reflect off objects that they hit. A CAT scan is the process of visually cutting the body into cross sections. However, another controversy runs deep in the issue of using CAT scans to find cancer tissue. The radiation required to examine a five milliliters lump is often considered simply too high for safety and has a possibility of just simply spreading the cancer to other body parts. A magnetic resonance imaging (MRI) takes advantage of the electromagnetic qualities of the hydrogen nucleus to produce an electric chart or visual (Internet Published June 7, 2000). While the most common form of breast exam is mammography, there are many critics of that procedure. Printed in Cancer Journal for Clinicians, scientists claim that, “mammograms missed 10% of cancers in women younger than 50, and 5% in women older than 50.” Cancer patients have said that the mammogram is often uncomfortable and takes too much time. However, one of the largest studies in this subject in medical history disagrees. In a cancer study conducted by the American Cancer Society, which is due to be released to the public in June of 2000, the organization does a twenty-year follow up on an experiment started in the early 70's. Based on a 96% follow up from 1993 to 1995, 4051 women had breast cancer. Out of those cancer patients, 2658 were alive (66%), and 1393 (34%) were dead. At the end of the twenty years period, those who were forced into examination were 20 times less likely to get cancer. One startling conclusion enforces a hypothesis dating back to the days of Darwin. Younger women are at increased risk for biologically more aggressive carcinoma, meaning that the future battle for curing cancer is not getting any easier. Which cancer growths are dependants upon the growth of blood vessels to nurture the cancer cells? New drugs are being developed to stop the growth of cancer cells by preventing nourishment of the cancers by new blood vessels. By cutting off the blood supply to the cells, they die, and thus are eliminated from the system. Although Dr. Gardner said that, “A cure for this kind of cancer has not found. There has been new research that has just come out about genes and cell mutation and the relationship to breast cancer.” Researchers from the Imperial Cancer Research Fund are the first to build a three dimensional model of an important region of a protein molecule found in the BRCA1 gene-linked to cancer. Genes hold the directions for proteins and then the proteins work controlling the life of the cells. Mutations in the genes that normally suppress tumor growth may be inactivated, thus starving the cell of the crucial brakes needed to halt the controlled division commonly found in cancer. Dr ...
