A sweeping new analysis adds to the evidence that many women who take hormone therapy during menopause are more likely to develop breast cancer—and remain at higher risk of cancer for more than a decade after they stop taking the drugs. The longer women took the medicine, the more likely they were to develop breast cancer. Experts say the findings could shape how women and their health care providers decide how to manage symptoms of menopause.
Studies have shown that your risk for breast cancer is due to a combination of factors. The main factors that influence your risk include being a woman and getting older. Most breast cancers are found in women who are 50 years old or older.
Research has shown that some things can increase your chance of getting breast cancer. These are called 'risk factors'. However, as we are all different, risk factors will not affect us all in the same way. One person may have many risk factors and not develop breast cancer, while another may have very few and be diagnosed with it.
Women undergoing in vitro fertilization have long worried that the procedure could raise their risk for breast cancer. After all, the treatment requires temporarily increasing levels of certain sex hormones to five or 10 times the normal. Two of those hormones, estrogen and progesterone, can affect the course of certain kinds of breast cancer.

Many of the most important risk factors for breast cancer are beyond your control, such as age, family history, and medical history. However, there are some risk factors you can control, such as weight, physical activity, and alcohol consumption. Be sure to talk with your doctor about all of your possible risk factors for breast cancer.
Breast cancer is now the most common cancer in the UK excluding non melanoma skin cancer. It is by far the most common cancer in women. Women who are overweight after their menopause have a higher risk of breast cancer than women who are not overweight.
