Hormonal therapy given after surgery is called adjuvant hormonal therapy. There are three primary uses for tamoxifen:1 1. Both tamoxifen and aromatase inhibitors can cause side effects. In 2012 and 2013, large studies found that 10 years of tamoxifen was better than 5 because it: lowered the incidence of breast cancer recurrence reduced the number of deaths from breast cancer … Radiation therapy can reduce this risk to about 6 percent … In this study, the researchers analyzed information that was collected as part of the BIG 1-98 study that was open from 1999 to 2003.

Don’t wait until the symptoms are intolerable and you have to stop taking the medicine. There are steps you can take to ease these side effects, including switching to a different type of hormonal therapy.
