Finding a lump in your breast can be a scary experience, but not all lumps and tumors are cancerous. One type of benign (non-cancerous) tumor is called a fibroadenoma. While not life-threatening, a fibroadenoma may still require treatment.
A fibroadenoma is a non-cancerous tumor in the breast that is commonly found in women under the age of 30. According to Mammotome, fibroadenomas are diagnosed in approximately 10 percent of women in the United States (Mammotome). African-American women are more likely to develop these tumors.
