Found a Breast Lump? What to Do, When to Worry, and How to Get a Same-Day Breast Ultrasound in London

Last Updated: March 2026 | Medically Reviewed by GMC-Registered Doctors at The Online GP by The Wellness

Finding a lump in your breast is frightening. Your mind goes to the worst-case scenario immediately. But here is the reality that most people do not hear in that initial moment of panic: the vast majority of breast lumps are not cancer.

According to Cancer Research UK, approximately 9 out of 10 breast lumps are benign. Fibroadenomas (solid, smooth, moveable lumps), breast cysts (fluid-filled sacs), fibrocystic changes, and fat necrosis account for the overwhelming majority of breast lumps found by women of all ages.

That said, every new breast lump should be assessed by a doctor. The purpose of investigation is not to assume the worst — it is to confirm the best, quickly and definitively.

This guide explains what to do when you find a breast lump, what causes breast lumps, when to be concerned, and how to get investigated rapidly in London without weeks of waiting.

What to Do When You Find a Breast Lump

Do not panic. Remind yourself that most breast lumps are benign. This is a statistical fact, not false reassurance.

Do not ignore it. Every new, persistent breast lump needs medical assessment. A lump that was not there before and does not go away after your next period should be checked.

See a doctor within two weeks. NICE guidelines recommend that any new breast lump should be assessed by a healthcare professional. If your NHS GP can see you promptly, that is a good first step. If they cannot — and in 2026, many patients report waits of 2+ weeks for routine appointments — a private GP consultation provides immediate access.

Do not Google yourself into a spiral. Online symptom checkers and forum posts are not clinical assessments. A doctor's examination and, if indicated, an ultrasound scan can provide definitive answers that no amount of internet searching can.

Common Causes of Breast Lumps

Understanding what causes breast lumps can help contextualise your experience while you wait for assessment.

Fibroadenomas are the most common breast lumps in women under 35. They are solid, smooth, round, and mobile — often described as feeling like a marble. They are entirely benign and often do not require treatment, though they should be confirmed on ultrasound.

Breast cysts are fluid-filled sacs that develop within breast tissue. They are extremely common, particularly in women aged 35–50, and often fluctuate with the menstrual cycle. Cysts can appear suddenly and may feel smooth, round, and sometimes tender. Ultrasound confirms them instantly — a cyst has a characteristic appearance that is unmistakable on ultrasound.

Fibrocystic changes cause lumpy, sometimes painful breast tissue that fluctuates with your cycle. This is a normal variation, not a disease, and affects up to 50% of women at some point.

Fat necrosis occurs when fatty breast tissue is damaged (from trauma, surgery, or radiation), forming a firm, round lump. It is completely benign.

Breast cancer accounts for approximately 1 in 10 investigated breast lumps. Warning features include a hard, irregular, fixed (non-mobile) lump, skin changes over the lump (dimpling, puckering, redness), nipple changes (inversion, discharge — particularly blood-stained), axillary (armpit) lymph node enlargement, or a lump that is growing. Having these features does not confirm cancer, and not having them does not exclude it — which is why investigation is always recommended.

When to Be Concerned: Red Flags

While most breast lumps are benign, certain features warrant urgent assessment:

• A hard, irregular lump that does not move freely

• Skin changes overlying the lump — dimpling, puckering, or orange-peel texture

• Nipple retraction (pulling inward) that is new

• Blood-stained nipple discharge

• A new lump in a woman over 50

• Swelling in the armpit

• A lump that is progressively enlarging

• Breast symptoms in a man (male breast cancer accounts for approximately 1% of all breast cancers)

If you have any of these features, see a doctor urgently. NICE recommends a two-week-wait urgent referral pathway for suspected breast cancer through the NHS. If you cannot access this pathway quickly, a same-day private GP consultation and breast ultrasound can provide rapid initial assessment.

Breast Ultrasound vs Mammogram: Which Do You Need?

Understanding the difference between these two imaging modalities helps you know what to expect and request.

Breast ultrasound uses high-frequency sound waves to create real-time images of breast tissue. It excels at distinguishing solid lumps from fluid-filled cysts (this distinction is immediate and definitive), evaluating specific palpable lumps, imaging dense breast tissue (common in women under 40), guiding needle biopsies or aspirations, and providing real-time assessment with no radiation exposure.

Mammography uses low-dose X-rays to image breast tissue. It excels at detecting microcalcifications (tiny calcium deposits that can indicate early cancer), population-level screening in women over 50, and imaging larger areas of breast tissue systematically.

In practice, they are complementary. For a woman who has found a specific lump, ultrasound is typically the first-line investigation — particularly for women under 40 or those with dense breast tissue. Mammography may be added depending on age and clinical findings.

At The Wellness, breast ultrasound is performed by a GMC-registered doctor who can immediately characterise your lump as solid, cystic, or complex — and explain what that means for you during the scan.

The Fast Track: From Discovery to Diagnosis

Today: Speak to a doctor (from £49). A phone or video consultation with a GMC-registered doctor at The Online GP. Your doctor takes a history, assesses risk factors, and arranges a same-day or next-day breast ultrasound if indicated.

Today or tomorrow: Doctor-performed breast ultrasound (from £195). A GMC-registered doctor performs your scan, identifies whether the lump is solid, cystic, or complex, characterises its features, checks axillary lymph nodes, and explains findings during the appointment.

Same day: Written report (within 2 hours). Your formal report is sent the same day. If the findings are reassuring — as they are in the vast majority of cases — you leave with peace of mind. If further investigation is needed, referral is arranged immediately.

This entire process can happen within 24 hours. Compare this to the NHS pathway, where GP appointment wait, referral processing, and breast clinic appointment can take 2–6 weeks — weeks of anxiety that a same-day scan eliminates.

Nine out of ten breast lumps are benign. But you deserve to know — not guess.

Frequently Asked Questions

I found a breast lump — what should I do? See a doctor within two weeks. Most lumps are benign, but every new lump should be assessed. If your NHS GP cannot see you quickly, a private consultation (from £49) and same-day breast ultrasound (from £195) provide rapid answers.

How much does a private breast ultrasound cost in London? At The Wellness, one-side breast ultrasound costs £195, bilateral costs £275, and breast and axilla (with lymph node check) costs £295. All scans are doctor-performed with a report within 2 hours.

Is breast ultrasound better than mammogram? They are complementary. Ultrasound is superior for evaluating specific lumps, cyst identification, dense breast tissue, and women under 40. Mammography is better for microcalcification detection and general screening over 50. Your doctor will advise on the right test.

Can I get a same-day breast ultrasound in London? Yes. The Wellness offers same-day appointments, subject to availability. Book via WhatsApp or email for the fastest response.

Does a breast ultrasound hurt? No. Breast ultrasound is painless. A water-based gel is applied to the skin and a smooth probe is moved over the breast. There is no compression (unlike mammography) and no radiation. The scan typically takes 15–20 minutes.
