Those taking estrogen can be added to the list.

Delaware, where I live, has the highest rate of breast cancer in the nation. We have lots of chemical plants and the duPont's. The Delaware River is polluted and we have toxic waste dumps. I have breast cancer.

Women at high risk of developing breast cancer are those who carry one of the rare inherited genes known to be responsible for hereditary breast cancer. Hereditary breast cancer accounts for 5 - 10% of all breast cancer cases. If someone has inherited one of the BRCA genes from one of their parents, each of their children has a 50% chance of inheriting that gene. A female inheriting the gene has a 50 - 80% chance of developing breast cancer. A male inheriting the gene has in increased, though still very low, risk of breast cancer. Women carrying the BRCA gene are the only ones who can be considered at high risk of breast cancer. For all other women in the US, the chance of developing breast cancer is one in eight if they live into their late 70s/80s ( 80% of breast cancers occur in women over the age of 50). There are known risk factors for breast cancer; but none of them can be described as making someone 'high risk'; they are just things that increase an individual's risk of breast cancer occuring, and most people who have one, two or even all the risk factors don't get breast cancer. The greatest risk factor is being female; over 99% of those diagnosed are women. The second greatest is age - 80% of those diagnosed are over 50, only 5% are under 40, fewer than 0.1% are under 30 and it's almost unheard of in under 25s. Genetic – but only 5-10% of breast cancers are genetic/hereditary Other recognised risk factors are: Having children at an older age or not at all. The more children a woman has may also slightly lower her risk. Breast-feeding helps protect against the disease. The longer a woman breastfeeds her children, the more she lowers her risk. Starting periods at a younger than average age (under 12) or having a late menopause (after 55) . Taking the contraceptive pill or hormone replacement therapy (HRT) causes a small increase in risk. However, the risk gradually returns to normal after you stop taking them. Being overweight (especially after the menopause). Regularly drinking more than 1 unit of alcohol per day slightly increases the risk of breast cancer. Having a previous diagnosis of breast cancer increases the risk of developing a new cancer in the other breast. These are only risk factors though; ticking one, some or all these boxes does not mean you will get breast cancer, and many people who are diagnosed with breast cancer have none of these risk factors.

As usual lo_mcg covers her breast cancer answers very well. I would like to add women who test positive for the p53 or the PTEN gene have a 50% lifetime risk for breast cancer. Women who used estrogen for more than 5 years have an increased risk of 35% and it is higher if progesterone was also used. There is an international study ongoing that will give better data. Women who received ionizing radiation have a 30% risk for breast cancer up to 20 years after treatment. Women diagnosed with LCIS are also at high risk and of course women who test positive for the BRCA 1 or 2 gene mutation are at high risk. These high risk people are at a risk over and above the basic risk factors for the disease, but even when added all together they represent a small portion of the population. All women’s risk increases with age and we all have a 1 in 8 lifetime risk for breast cancer.
