Breast lump
breast surgery · oncological surgery · breast lump · Gdańsk
A palpable breast lump does not always mean cancer, but it always requires proper assessment. A lesion may be benign, inflammatory, cystic or malignant — which is why medical examination, analysis of ultrasound or mammography, and in selected cases biopsy or surgical removal are essential.
If you feel a lump, have a concerning ultrasound or mammography result, or have been advised to undergo further diagnosis, start with a surgical consultation. The doctor will assess whether core needle breast biopsy, observation or surgical breast lump removal is needed.

What can a breast lump be?
A breast lump is a palpable thickening, nodule or lesion visible on imaging such as ultrasound, mammography or magnetic resonance imaging. A lesion may have different causes — from a benign cyst, fibroadenoma or inflammatory change to a lesion requiring further oncological diagnosis.
The most important thing is not to assume either the worst or the safest scenario. A breast lump requires structured assessment: medical history, breast examination, analysis of imaging results, and in some cases core needle biopsy or surgical removal of the lesion.
Most important: if you have felt a new breast lump, do not diagnose yourself and do not postpone the visit. Most breast lesions do not necessarily mean cancer, but each one requires specialist assessment.
When should a breast lump be especially concerning?
- the lump is new, hard, irregular or grows quickly,
- the lesion does not disappear after menstruation or grows from cycle to cycle,
- there is skin dimpling, nipple retraction or a change in breast shape,
- bloody or one-sided nipple discharge appears,
- the breast skin is red, thickened or resembles an “orange peel”,
- enlarged lymph nodes are palpable in the armpit,
- ultrasound, mammography or MRI was described as suspicious, for example BI-RADS 4 or 5.
Warning symptoms — do not delay consultation:
- a new, rapidly enlarging lump,
- bloody nipple discharge,
- nipple or breast skin retraction,
- skin changes, ulceration, redness or swelling of the breast,
- a palpable breast lump together with enlarged lymph nodes in the armpit.
Does every breast lump mean cancer?
No. Many breast lesions are benign. They may be cystic, fibrous, inflammatory or hormone-related. However, it is not possible to assess whether a lesion is safe by touch alone. Further management depends on medical examination, ultrasound or mammography findings and — if needed — biopsy results.
In practice, the key question is not “is this definitely cancer?”, but “has this lesion been properly assessed?”. Only after structured diagnosis can the doctor decide whether observation, biopsy, imaging follow-up or removal is appropriate.
What does BI-RADS mean in breast lump assessment?
BI-RADS is a system used to describe breast imaging results. It helps organise information about whether a lesion appears benign, requires follow-up or should undergo further diagnosis. In simplified terms: BI-RADS 1 and 2 usually indicate a normal result or a benign lesion, BI-RADS 3 requires follow-up, and BI-RADS 4 and 5 usually indicate the need for biopsy or urgent diagnosis.
If your report includes BI-RADS 4 or BI-RADS 5, do not interpret it on your own and do not wait. Book a consultation to plan the next step.
What does the diagnostic pathway for a breast lump look like?
In the case of a breast lump, the goal is not to perform any procedure as quickly as possible, but to choose the right next step. Sometimes follow-up is enough, sometimes biopsy is needed, and sometimes the lesion should be surgically removed.
The doctor takes a medical history, examines the breasts, reviews ultrasound, mammography or MRI results and discusses possible next steps.
Book consultation →Performed when a tissue sample is needed for histopathological examination. It helps determine the nature of the lesion and plan treatment.
See biopsy →Considered when the lesion requires diagnostic or therapeutic excision. The removed material is sent for histopathological examination.
See lump removal →The right pathway is determined by the doctor after analysing symptoms, physical examination and imaging results. This page describes the problem of a “breast lump”; procedure details are available on the service pages.
Who consults and treats breast lesions?
general and oncological surgeon
She deals with diagnosis and treatment of breast diseases — both benign and malignant. She helps interpret imaging results, qualify patients for biopsy, plan treatment and perform breast surgery.
general and oncological surgeon
He consults patients with lesions requiring surgical assessment and performs breast surgery procedures. He discusses possible treatment methods, safety, procedure scope and next steps.
Do you feel a breast lump or have a concerning test result?
Do not postpone diagnosis. Book a consultation and find out whether observation, biopsy or removal is needed.
Common concerns before consultation
The statements below are not patient reviews. They are educational examples showing concerns women often bring to the doctor.
This is a very common concern. That is why structured diagnosis is needed — examination, review of ultrasound or mammography, and a decision whether biopsy is needed.
Such a result usually requires further diagnosis, often biopsy. A consultation helps calmly plan the next step and avoid information chaos.
During the consultation, the doctor explains the possible surgical approach, scar, recovery, histopathological examination and further management.
Frequently asked questions about a breast lump
Does every breast lump mean cancer?
No. Many breast lumps are benign, such as cystic, fibrous, inflammatory or hormone-related lesions. However, every new or concerning lesion requires medical assessment and imaging.
When is core needle breast biopsy needed?
Biopsy is considered when imaging shows a lesion that requires histopathological assessment, for example when cancer is suspected or the nature of the lump is unclear. The indication is determined by the doctor.
Can a breast lump be removed immediately?
Not always. In many cases, imaging and biopsy are needed before surgery. Sometimes biopsy helps avoid unnecessary surgery, and sometimes it helps plan the right surgical treatment.
What happens to the lump after removal?
The removed tissue should be sent for histopathological examination. The result helps determine the nature of the lesion and decide whether further follow-up or treatment is needed.
Does breast biopsy hurt?
Biopsy is usually performed under local anaesthesia. The patient may feel pressure or discomfort, but the aim of anaesthesia is to reduce pain during the procedure.
Can I just observe the lump and wait?
Observation is possible only if the doctor considers it safe based on examination and imaging results. A new, growing, hard or suspicious lesion should not be observed on your own without consultation.
Where should I start if I feel a breast lump?
It is best to start with a medical consultation and imaging examination or review of existing results. The doctor will decide whether follow-up, core needle biopsy, additional tests or removal is needed.

The information on this page is for general educational purposes and does not replace medical consultation. A breast lump, thickening, pain, nipple discharge, breast skin change or concerning imaging result requires individual medical assessment. The need for observation, biopsy, additional diagnosis, surgery or histopathological examination is determined by the doctor after analysing symptoms and test results.
