Citando:
"Many survivors of breast cancers that are sensitive to estrogen are advised to take hormone-suppressing drugs such as tamoxifen for five years, to cut their odds for a recurrence.
Tamoxifen can have onerous side effects, however. Now, new research finds that taking an alternative, and less troublesome, class of medications for a full decade can reduce the risk for recurrence even more -- without affecting a woman's quality of life.
The newer class of hormone-suppressing drugs are called aromatase inhibitors, and include drugs such as letrozole (Femara), anastrozole (Arimidex) and exemestane (Aromasin)."

"Women should be offered 10 years of drugs to prevent the return of breast cancer, rather than five as now, according to a major study showed longer-term treatment reduced the numbers whose disease came back.
Huge numbers of women in the UK and around the world are already taking hormone therapy – drugs that block oestrogen in the body that can fuel breast cancer growth. Many abandon them within the first few years because of the side-effects or because they feel well and do not want to be on medication."
