Types of Breast Cancer
Invasive Ductal Carcinoma
The abnormal cancer cells that began forming in the milk ducts have spread beyond the ducts into other parts of the breast tissue. Invasive cancer cells can also spread to other parts of the body. It is also sometimes called infiltrative ductal carcinoma.
- Most common type of breast cancer, making up 70- 80% of all breast cancer diagnoses.
- The type of breast cancer that can most commonly affect men.
Invasive Lobular Carcinoma
ILC sometimes called infiltrating lobular carcinoma, is the second most common type of breast cancer after invasive ductal carcinoma (cancer that begins in the milk-carrying ducts and spreads beyond it).
According to the American Cancer Society, more than 180,000 women in the United States find out they have invasive breast cancer each year.
Facts about Breast Cancer
Facts according to breastcancer.org:
- About 1 in 8 U.S. women (about 12.4%) will develop invasive breast cancer over the course of her lifetime.
- In 2018, an estimated 266,120 new cases of invasive breast cancer are expected to be diagnosed in women in the U.S., along with 63,960 new cases of non-invasive (in situ) breast cancer.
- About 2,550 new cases of invasive breast cancer are expected to be diagnosed in men in 2018. A man’s lifetime risk of breast cancer is about 1 in 1,000.
- Breast cancer incidence rates in the U.S. began decreasing in the year 2000, after increasing for the previous two decades. They dropped by 7% from 2002 to 2003 alone. One theory is that this decrease was partially due to the reduced use of hormone replacement therapy (HRT) by women after the results of a large study called the Women’s Health Initiative were published in 2002. These results suggested a connection between HRT and increased breast cancer risk.
- About 40,920 women in the U.S. are expected to die in 2018 from breast cancer, though death rates have been decreasing since 1989. Women under 50 have experienced larger decreases. These decreases are thought to be the result of treatment advances, earlier detection through screening, and increased awareness.
- For women in the U.S., breast cancer death rates are higher than those for any other cancer, besides lung cancer.
- Besides skin cancer, breast cancer is the most commonly diagnosed cancer among American women. In 2017, it’s estimated that about 30% of newly diagnosed cancers in women will be breast cancers.
