Breast cancer is the most mon cancer and the second leading cause of cancer deaths in won in the United States. In 2008 nike lunarmax flyknit chukka sp nyc , approximately 184,450 patients were estimated to be diagnosed with invasive breast cancer, and an estimated 40,930 were estimated to die of this disease. Furthermore, over 50,000 female carcinoma in situ breast cases would have been diagnosed. The etiology of breast cancer is poorly understood with multiple geic and environntal ftors involved in the initiation and progression of cancer. Scandinavian Twin Study: For years nike free flyknit chukka wolf grey blue , there has been a hot debate as to whether the cause of breast cancer is geic or environntal. Then in 2000, Lichtenstein and his colleagues at the Karolinska Institute in Sweden publied their study of 44,788 pairs of twins from the Swedi, Dani, and Finni twin registries. In this study, they looked at cancer risk with 28 different types of cancers and did statistical modeling of geic and hereditary contributions in eleven different cancer types. For breast cancer nike free flyknit chukka game royal , they clearly owed that only 27% of breast cancers were due to geic ftors. This was an even l ourred earlier in life. For example nike free flyknit chukka tarp green , in families with four or more cases of breast or ovarian cancer under the age of 60, over 80% are found to have a damaged version of BRCA1 or BRCA2. If a patient is a carrier of one or both of the BRCA1 and BRCA2 genes, her risk of breast cancer dramatically increases. Aording to estimates of lifeti risk, about 13.2% (132 out of 1,000 individuals) of won in the general population will develop breast cancer, pared with estimates of 36-85% (360850 out of 1 nike roshe run flyknit grey & black trainers ,000) of won with an altered BRCA1 or BRCA2 gene. In other words, won with an altered BRCA1 andor BRCA2 gene are up to eight tis more likely to develop breast cancer than won without alterations in those genes. The BRCA1 mutation confers a higher risk than a BRCA2 mutation. Won who inherit a damaged BRCA1 gene have a 60-85% chance of developing breast cancer at so stage in their lives and a 20-40% chance of developing on directed on the BRCA genes, the majority of patients with a family history of breast cancer are BRCA1 and BRCA2 negative. Even in these BRCA negative patients, however nike roshe run flyknit uk , there is an increased risk of developing cancer with a family history of breast cancer. Six ftors (unrelated to BRCA genes) have been studied in patients with a family history of breast cancer. They are as follows:1.
