Age

Menses
Beginning menses early or starting menopause late can increase risk
History
Survivors of breast cancers are at risk of being diagnosed again
Radiotherapy
Radiotherapy to the chest can increase the risk in later life
Risk factors that can be changed:
Inactivity
A sedentary lifestyle puts you at a higher risk
Weight
Postmenopausal obesity can increase the risk of breast cancer
Hormones
Hormonal treatment can increase breast cancer risk
Pregnancy
Pregnancy problems can increase the risk of breast cancer
Habits
