Understanding Breast Cancer

Although the precise causes of breast cancer are unclear, we know what the main risk factors are.Still, most women considered at high risk for breast cancer do not get it, while many who do have no known risk factors. Among the most significant factors are advancing age and a family history of breast cancer. Risk increases slightly for a woman who has had a benign breast lump and increases significantly for a woman who has previously had cancer of the breast or the ovaries.

Most cases of breast cancer are not inherited.These cancers are associated with genetic changes that occur only in breast cancer cells (somatic mutations) and occur during a person's lifetime.In hereditary breast cancer, the way that cancer risk is inherited depends on the gene involved.For example, mutations in the BRCA1 and BRCA2 genes are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase a person's chance of developing cancer.In other cases, the inheritance of breast cancer risk is unclear.It is important to note that people inherit an increased risk of cancer, not the disease itself.Not all people who inherit mutations in these genes will develop cancer.

Generally, women over 50 are more likely to get breast cancer than younger women, and African-American women are more likely than Caucasians to get breast cancer before menopause.A link between breast cancer and hormones is gradually becoming clearer. Researchers think that the greater a woman's exposure to the hormone estrogen, the more susceptible she is to breast cancer.Estrogen tells cells to divide; the more the cells divide, the more likely they are to be abnormal in some way, possibly becoming cancerous.
