Quick answer

What is Breast lump?

Finding a breast lump is common and, reassuringly, most breast lumps are not cancer — many are harmless (benign). Common benign causes include fluid-filled cysts, harmless solid lumps (such as fibroadenomas, which are common in younger women), changes related to the menstrual cycle (lumpy, "fibrocystic" breast tissue), and lumps related to infection (such as an abscess) or injury.

  • How it is treated: A new breast lump is assessed by a doctor, who will examine the breast and, in most cases, arrange further assessment — often at a specialist breast clinic.
  • Self-care: Being "breast aware" — knowing what is normal for your breasts so you notice any change — and attending breast screening when invited help catch changes early.
  • When to seek help: See a GP promptly about any new breast lump, or a lump in the armpit, even if it is painless — most are harmless, but all should be checked.

What it is

Finding a breast lump is common and, reassuringly, most breast lumps are not cancer — many are harmless (benign). Common benign causes include fluid-filled cysts, harmless solid lumps (such as fibroadenomas, which are common in younger women), changes related to the menstrual cycle (lumpy, "fibrocystic" breast tissue), and lumps related to infection (such as an abscess) or injury. However, because a breast lump can occasionally be a sign of breast cancer, and because it is not possible to tell for certain just by feeling it, the key message is that any new or unusual breast lump should always be checked promptly by a doctor. This is not a reason for panic — most turn out to be harmless — but it is important to get it assessed rather than wait. Being "breast aware" (knowing what is normal for you, so you notice changes) helps.

How it is treated

A new breast lump is assessed by a doctor, who will examine the breast and, in most cases, arrange further assessment — often at a specialist breast clinic. There, "triple assessment" may be used: a clinical examination, imaging (a mammogram and/or ultrasound, depending on age), and, where needed, a sample (biopsy) of the lump — together these accurately determine whether a lump is harmless or needs treatment. Many lumps are confirmed benign and need no treatment, or simple treatment (such as draining a cyst); some benign lumps are monitored or removed if bothersome. If a lump is found to be cancer, it is treated by a specialist team, and being diagnosed early gives the best outcomes — which is another reason prompt checking matters. The reassuring message is that most breast lumps are harmless, but any new lump should be checked promptly to be sure, using accurate tests.
