What Is Breast Cancer?
Breast cancer is a disease in which cells in the breast grow out of control. There are different kinds of breast cancer. The kind of breast cancer depends on which cells in the breast turn into cancer.
Breast cancer can begin in different parts of the breast. A breast is made up of three main parts: lobules, ducts, and connective tissue. The lobules are the glands that produce milk. The ducts are tubes that carry milk to the nipple. The connective tissue (which consists of fibrous and fatty tissue) surrounds and holds everything together. Most breast cancers begin in the ducts or lobules.
Breast cancer can spread outside the breast through blood vessels and lymph vessels. When breast cancer spreads to other parts of the body, it is said to have metastasized.
Kinds of Breast Cancer
The most common kinds of breast cancer are—
There are several other less common kinds of breast cancer, such as Paget’s disease, medullary, mucinous, and inflammatory breast cancer.
Ductal carcinoma in situ (DCIS) is a breast disease that may lead to invasive breast cancer. The cancer cells are only in the lining of the ducts, and have not spread to other tissues in the breast.
Who is mainly affected by breast cancer?
Breast cancer is one of the most common cancers among women, second only to skin cancer. It’s most likely to affect women over the age of 50.
Though rare, men can also develop breast cancer. Approximately 2,600 men develop male breast cancer every year in the United States, making up less than 1% of all cases.
Transgender women are more likely to develop breast cancer compared to cisgender men. Additionally, transgender men are less likely to develop breast cancer compared to cisgender women.
What age does breast cancer occur?
Breast cancer is most often diagnosed in adults over the age of 50, but it can occur at any age.

What race is most affected by breast cancer?
Overall, women who are non-Hispanic white have a slightly higher chance of developing breast cancer than women of any other race or ethnicity. Women who are non-Hispanic Black are almost as likely as non-Hispanic white women to develop the disease. Statistically, women who are Asian, Hispanic or Native American are the least likely to develop breast cancer.
