Causes of brest cancer - genetic mutation brca1 and brca2 gene mutation
Hyperestrogen condition, obesity, fatty diet, high socioiconomic status, early menarch ,late menopause
2- in women both gene brca1 and brca2 mutation are cause breast cancer but in man only brca1 is involved
In female estrogen level is high ,more fatty or breast tissue compair to make
3- do screening by mammography
4- self examination of breast

what causes breast cancer ? what causes breast cancer more in woman than man? what are the main prevention for breast cancer in woman? identify one educational approach that has been developed to address breast cancer? Please explain in 400 words
Approximately 3% of women aged 40-50 have breast cancer. A woman with breast cancer has a 90% chance of positive test from a mammogram, while a woman without breast cancer has a 2% chance of a positice result. What is the probability that a woman has breast cancer given that she just had a positive test?
Of all 40-year-old women, 8% have breast cancer. If a woman has breast cancer, a mammogram with give a positive indication for cancer 80% of the time. If a woman does not have breast cancer, a mammogram will give a positive indication for cancer 2% of the time. If a 40-year-old woman’s mammogram gives a positive indication for a cancer, what is the probability that she has cancer?
A woman is worried that she might have breast cancer. The standard test for breast cancer is mammography. From research she found online, she discovers the sensitivity for the mammography screening is 83% and the specificity is 96% . Her doctor has told her that one in 45 women in her forties will have breast cancer. Based on the sensitivity, specificity, and prevalence, determine the positive predictive value (PPV) for the mammography screening. Express your answer to three decimal places.
About 20 women in 80,000 have breast cancer. Suppose the mammogram detecting breast cancer when a woman has breast cancer is 0.90 and the mammogram detecting breast cancer on a woman who does not have breast cancer is 0.01. If a woman has breast cancer, what is the probability that the mammogram will not detect breast cancer? If the mammogram shows breast cancer, what is the probability that she truly has breast cancer? If the mammogram shows a woman has...
A woman is worried that she might have breast cancer. The standard test for breast cancer is mammography. From research she found online, she discovers the sensitivity for the mammography screening is 89% and the specificity is 96%. Her doctor has told her that one in 61 women in her forties will have breast cancer. Based on the sensitivity, specificity, and prevalence, determine the positive predictive value (PPV) for the mammography screening. Express your answer to three decimal places. PPV...
what is/are the cause/causes of the disease breast cancer
In the general population, one woman in eight will develop breast cancer. Research has shown that 1 woman in 600 carries a mutation of the BRCA gene. Seven out of 10 women with this mutation develop breast cancer. Find the probability that a randomly selected woman will develop breast cancer given that she has a mutation of the BRCA gene. (Round to one decimal place as needed.)
Studies show that approximately one woman in seven who live to be 90 will develop breast cancer. Assume that of those women who develop breast cancer, a test for breast cancer is negative 2% of the time (i.e., false negative). Also, assume that the test for breast cancer is negative 85% of the time. a) What is the probability that a randomly chosen woman develops breast cancer? b) What is the probability that a randomly chosen woman tests negative for...
Breast cancer is the most common non-skin malignancy among women in the United States, and it is the second leading cause of death from cancer among women (lung cancer ranks Örst). A mammogram is a diagnostic procedure designed to quickly detect breast cancer. Such a test can exhibit two kinds of errors: One error is known as a false positive: The test incorrectly indicates cancer in a healthy woman. The other error (which is more serious error in this situation)...
