Menopause itself is not associated with an increased risk of developing cancer. However, the rates of many cancers, including breast cancer, do increase with age. In addition, some of the drugs used to manage menopausal symptoms may increase or decrease a person’s cancer risk.
Can menopause trigger breast cancer?
Starting menopause after age 55 increases a woman’s risk of breast cancer and endometrial cancer. That’s probably because she’s been exposed to more estrogen. During a woman’s menstrual cycle, estrogen stimulates the uterus and breast tissue.
Why is breast cancer common after menopause?
After menopause (when the ovaries stop making estrogen), most of a woman’s estrogen comes from fat tissue. Having more fat tissue after menopause can raise estrogen levels and increase your chance of getting breast cancer. Also, women who are overweight tend to have higher blood insulin levels.
How common is premenopausal breast cancer?
While breast cancer in older women is clearly much more common, around 7% of the women diagnosed with breast cancer are under 40, when most women are still premenopausal. In fact, according to the Office for National Statistics, 42.4% of all cancers occurring in women aged 15-49 is breast cancer.

What is the average age a woman gets breast cancer?
Breast cancer is most common in females over the age of 50 years . According to the National Cancer Institute (NCI) , doctors most often diagnose breast cancer in females aged 55–64 years. Based on data from 2012–2016, the median age of diagnosis in females with breast cancer was 62 years old .
What is the highest risk factor for breast cancer?
Gender. Being a woman is the most significant risk factor for developing breast cancer. Although men can get breast cancer, too, women’s breast cells are constantly changing and growing, mainly due to the activity of the female hormones estrogen and progesterone.
Does breast cancer grow slower after menopause?
These estrogen-fueled breast cancers — known as estrogen-receptor-positive cancer (ER-positive) — tend to grow more slowly and be less deadly. That means women usually require less aggressive treatment and, as a group, have a better prognosis and lower risk of recurrence.
Is premenopausal breast cancer worse?
Women who develop breast cancer in the premenopausal years are more likely to have a higher tumor grade. The tumor grade is a measure of the aggressiveness of a tumor based on how normal or abnormal the cells look under a microscope.
Is breast cancer less likely after menopause?
Late menopause increases the risk of breast cancer. Postmenopausal women have a lower risk of breast cancer than premenopausal women of the same age and childbearing pattern.
