|Breast Biopsy Results Frequency of various benign and malignant
breast lumps among patients who have had breast biopsies Several
noncancerous (benign) conditions can appear as a lump or cause a
change in the appearance of your breasts. If you notice a change
that persists over 10 days or past your monthly cycle, call your
doctor immediately. While it’s true that eight out of 10 breast
lumps are noncancerous, a biopsy is the only way to tell
definitively whether a solid lump is cancerous or not. Some
noncancerous breast lumps may not require treatment. Benign
lumps do not change into cancerous lumps. However, because
cancer sometimes develops near benign lumps, your doctor will
probably want you to have more frequent checkups. Some common,
noncancerous breast changes are fibrocystic conditions, cysts,
fibroadenoma and mastitis. Fibrocystic Breast Condition This

ages 35 to 50. Symptoms
