Breast Cancer Treatment and Awareness
An NHS and WHO-aligned guide to how breast cancer is treated, what the warning signs are, and why early detection transforms survival. All content reviewed against NHS and WHO guidelines.
Treatment
How breast cancer is treated
Breast cancer treatment has advanced substantially over the past 30 years. Today, most women with early breast cancer are cured. Treatment depends on the type, size, stage and receptor status of the tumour, as well as on individual circumstances. Most people receive more than one type of treatment, planned by a multidisciplinary team (MDT) of surgeons, oncologists, radiologists and specialist nurses.
The six main treatment modalities are described below. Full clinical detail — including NHS patient pathways, side-effect management and the evidence base for each approach — is on the breast cancer treatment sub-page.
Surgery
Surgery is the most common first treatment for breast cancer. It may involve removing the tumour only (lumpectomy/wide local excision) or the entire breast (mastectomy), depending on tumour size, location and personal preference.
Most women with early breast cancer have a choice between lumpectomy with radiotherapy or mastectomy. Both have equivalent survival outcomes when the cancer is suitable for either approach. Sentinel lymph node biopsy is used to check whether the cancer has spread to the lymph nodes, and is now standard practice for most early breast cancers.
Chemotherapy
Chemotherapy uses medicines to destroy cancer cells throughout the body. It may be given before surgery (neoadjuvant) to shrink a tumour, or after surgery (adjuvant) to reduce the risk of recurrence.
Common chemotherapy regimens for breast cancer include FEC-T, EC-T and TC. Treatment is usually given in cycles every three weeks, with each course lasting three to six months. Side effects — including hair loss, fatigue and increased infection risk — are temporary and well managed with modern supportive care.
Radiotherapy
Radiotherapy uses high-energy radiation to destroy any remaining cancer cells after surgery. It is standard after a lumpectomy and is increasingly used after mastectomy in higher-risk cases.
Most women receive radiotherapy to the breast or chest wall for three to five weeks. In suitable cases, a condensed five-fraction course (FAST Forward) can be delivered in one week with equivalent outcomes. Side effects — skin redness, fatigue — typically resolve within a few weeks of treatment ending.
Hormone Therapy
Around 80% of breast cancers are hormone-receptor positive (ER+), meaning oestrogen drives their growth. Hormone therapy blocks this fuel — reducing the risk of recurrence by up to 50%.
Tamoxifen (for pre-menopausal women) and aromatase inhibitors such as letrozole and anastrozole (for post-menopausal women) are taken as daily tablets for five to ten years. They are among the most effective cancer treatments ever developed. Side effects, including joint aches and hot flushes, are manageable for most women.
Targeted Therapy
Targeted therapies attack specific features of cancer cells, leaving healthy cells largely unaffected. They have transformed outcomes for HER2-positive and BRCA-related breast cancers.
Trastuzumab (Herceptin) targets HER2-positive breast cancer and has halved recurrence rates in this group. Pertuzumab, T-DM1 and lapatinib extend options further. PARP inhibitors (olaparib, niraparib) are used in BRCA-mutation carriers. CDK4/6 inhibitors (palbociclib, ribociclib) extend progression-free survival in advanced hormone-positive disease.
Immunotherapy
Immunotherapy helps the immune system recognise and attack cancer cells. It is now standard of care for certain high-risk triple-negative breast cancers — previously one of the hardest subtypes to treat.
Pembrolizumab (Keytruda) combined with chemotherapy is approved by NICE for early-stage, high-risk triple-negative breast cancer with PD-L1 expression. It significantly increases pathological complete response rates and event-free survival compared to chemotherapy alone.

Our detailed treatment page covers every stage of the NHS patient pathway — from diagnosis to adjuvant therapy — including questions to ask your breast care team, information on clinical trials, and what to expect at each stage.
Treatment by subtype
Different cancers, different treatments
The treatment your team recommends depends significantly on the subtype of breast cancer — which is determined by the receptors expressed by the cancer cells. The three main receptors tested are oestrogen (ER), progesterone (PR) and HER2.
Surgery + hormone therapy (tamoxifen or aromatase inhibitor). CDK4/6 inhibitors for advanced disease.
Learn more →Surgery + trastuzumab (Herceptin) ± pertuzumab. T-DM1 for residual disease. Transformed prognosis since 2000.
Learn more →Chemotherapy ± immunotherapy (pembrolizumab). PARP inhibitors for BRCA carriers. Aggressive but chemo-sensitive.
Learn more →Chemotherapy first (to shrink), then surgery, then radiotherapy. Requires urgent specialist referral.

Know the signs. Act early. Survive.
The single biggest factor in surviving breast cancer is finding it early. A cancer caught at Stage 1 has a five-year survival rate of around 98%. The same cancer caught at Stage 4 has a survival rate of around 26%. That difference — almost entirely explained by how early the cancer is detected — is why awareness matters so much.
Know what's normal for you
Breasts change throughout life — with your menstrual cycle, age and weight. The NHS approach is not a formal monthly self-exam but regular breast awareness: knowing how your breasts normally look and feel so any change stands out.
Touch, Look, Check
Touch your breasts and underarms for lumps or thickening. Look in the mirror — with arms raised and lowered — for changes in shape, size or skin. Check for any of the warning signs below and act on them.
Know the warning signs
A lump or thickening; skin changes (dimpling, puckering, redness); a change in nipple position; nipple discharge; persistent pain in one area; or swelling under the arm or around the collarbone.
See your GP without delay
If you notice any change that is not normal for you, contact your GP the same day or the next. You will not be wasting their time. If needed, they will refer you to a specialist breast clinic within 14 days under the NHS two-week wait rule.
NHS breast cancer warning signs — see your GP if you notice any of these
A new lump or thickening in the breast or armpit
A change in the size, shape or feel of either breast
Skin changes — dimpling, puckering, redness or an orange-peel texture
A change in the position or shape of the nipple
Nipple discharge (not breast milk)
Persistent pain in one area of the breast or armpit

Screening
NHS breast screening — what you need to know
The NHS Breast Screening Programme invites all women aged 50 to 71 for a mammogram every three years. It has contributed significantly to reducing breast cancer mortality in the UK since its introduction in 1988. If you have received an invitation, attend — it takes around 30 minutes and the evidence that it saves lives is strong.
Women under 50 with a significant family history of breast cancer may be eligible for earlier or more frequent screening. Speak to your GP if you are concerned about your family history.
Who is invited for NHS breast screening?
All women aged 50–71 are automatically invited every three years. Women outside this age group can still ask for a referral if they have concerns or a family history.
What does a mammogram involve?
The breast is placed between two plates and compressed briefly while an X-ray image is taken. It takes around 30 minutes and can be uncomfortable, but is not usually painful.
What if I have dense breasts?
Dense breast tissue can make mammograms harder to read. If you are concerned, speak to your GP — supplemental ultrasound or MRI may be appropriate depending on your risk profile.
Does screening prevent breast cancer?
No — screening does not prevent breast cancer. It finds it earlier, when treatment is more effective and survival rates are significantly higher.

The global gap
Survival should not depend on where you were born
In the UK, over 85% of women diagnosed with breast cancer survive at least five years. In Pakistan, Bangladesh and much of sub-Saharan Africa, the same disease kills more than half the women it affects — not because treatments don't exist, but because cancers are found too late.
The treatments described on this page are available on the NHS. In low-income countries, most women have no access to mammography, no structured screening programme, and no subsidised treatment. The global picture will not change until that access gap closes.
World Aid Network's breast cancer programme funds mobile screening in South Asia, bringing early detection to communities with no local clinic. A donation of £27 covers one complete screening.
