Celebrities such as Julia Louise-Dreyfus, Olivia Newton-John, Christina Applegate and Cynthia Nixon have revealed their breast cancer diagnoses, helping raise awareness for the most common cancer to affect women. It’s the second most common cause of cancer death in females.
How common is breast cancer?
1 in 8 women will develop invasive breast cancer over the course of their lifetime. According to the American Cancer Society, an estimated 266,120 cases of invasive breast cancer are expected to be diagnosed in women in the US with 63,960 cases of non-invasive breast cancer, a rise from last year.
40,920 women and 480 men are expected to die this year of breast cancer.
What are the risk factors for breast cancer?
Risk factors for breast cancer include:
- Age greater than 50
- Family History
- BRAC1 and BRAC2 genetic mutations
- Alcohol use
- Never been pregnant or becoming pregnant for the first time over 35 years old
- Early menarche at age 11 or younger
- Obesity, especially after menopause
- Dense breasts
- Lack of physical activity
- Use of oral contraceptives
- Previous “precancerous” tumors such as atypical hyperplasia
- DES exposure
- Previous radiation therapy
How is breast cancer staged?
Breast cancer is staged based on size of the tumor, if lymph nodes are affected and whether the cancer has spread to distant areas of the body. Prognosis varies greatly on the stage.

Is family history a huge factor?
85% of breast cancer cases occur in women with NO family history.
Screening of breast cancer
Mammograms are the first line screening tool for breast cancer and are currently recommended biennial for women aged 50-74. However for those at higher risk, mammogram screening should start earlier, with possible follow-up ultrasound, and be performed more regularly.
