What Is Breast Cancer and Why Early Detection Matters
3D medical illustration showing a breast tumour and surrounding lymphatic pathways
Breast cancer occurs when cells in the breast tissue begin to grow and divide abnormally, forming a tumour. These cells can invade nearby tissues and, over time, spread to other parts of the body through the lymphatic system or bloodstream — a process called metastasis.
The illustration above highlights what this looks like at the anatomical level: the tumour mass (shown in red and purple) sitting within breast tissue, while the green channels represent lymphatic vessels through which cancer cells can travel to distant sites, including the underarm lymph nodes.
⚠️ Why Timing Is Everything
Breast cancer found at Stage I has a near-100% 5-year survival rate. By Stage IV, that drops to around 28%. The difference is often simply: noticing something is different and acting on it promptly.
Types of Breast Cancer You Should Know About
- Invasive Ductal Carcinoma (IDC) — Most common type; starts in the milk ducts and invades surrounding tissue
- Invasive Lobular Carcinoma (ILC) — Begins in the milk-producing lobules; can be harder to detect on mammograms
- Ductal Carcinoma In Situ (DCIS) — Non-invasive; confined to ducts; highly treatable when found early
- Triple-Negative Breast Cancer — Aggressive; lacks common receptors; requires specific treatment
- Inflammatory Breast Cancer (IBC) — Rare but fast-moving; causes redness and swelling rather than a lump
- HER2-Positive Breast Cancer — Grows quickly but responds well to targeted therapies

6 Early Signs of Breast Cancer Every Woman Should Recognise
Key symptoms of breast cancer — image source: Everyday Health
Most breast cancers are found by women themselves — during a shower, while getting dressed, or by chance. That's why knowing what to look for is genuinely life-saving. The six symptoms below are the most important to be aware of.
- Lump in the Breast or Armpit
A new, hard, or irregular lump — even if painless - Inverted Nipple or Discharge
Nipple turning inward or fluid (not breast milk) leaking out - Breast Dimpling or Skin Changes
Skin that looks puckered, orange-peel textured, or thickened - Change in Breast Shape or Size
Unexplained swelling, shrinkage, or asymmetry in one breast - Breast or Nipple Pain
Persistent pain in one spot that doesn't go away with your cycle - Swollen Lymph Nodes
Swelling in the armpit or around the collarbone, even without a lump
How to Do a Monthly Breast Self-Examination (BSE)
A monthly breast self-exam takes fewer than five minutes and should be done around 3–5 days after your period ends, when breasts are least tender.
Step-by-Step Breast Self-Exam
- Stand in front of a mirror with arms at your sides. Look for any visible changes in shape, size, or skin texture
- Raise your arms overhead and look again from the front and both sides
- Lie down. Place your right hand behind your head. Use the left hand's three middle fingers to feel the right breast in circular motions — from the nipple outward
- Apply light, medium, and then firm pressure to check all layers of breast tissue
- Repeat on the left side. Also feel the armpit area on each side
- Gently squeeze each nipple to check for discharge
ℹ️ Important Reminder
A lump doesn't always mean cancer — most are benign cysts or fibroadenomas. However, any new or unusual lump must be evaluated by a doctor. Never wait to "see if it goes away."

Breast Cancer Risk Factors: Who Is More Vulnerable?
Non-Modifiable Risk Factors
These are factors you cannot change, but knowing them helps you and your doctor plan appropriate screening:
- Being female (though men can also develop breast cancer)
- Age over 40 years
- Family history of breast or ovarian cancer (mother, sister, daughter)
- Carrying BRCA1 or BRCA2 gene mutations
- Dense breast tissue (makes mammograms harder to read)
- Early menstruation (before age 12) or late menopause (after 55)
- Previous history of breast cancer or certain non-cancerous breast conditions
Modifiable Risk Factors
These are lifestyle-related risks that you can actively reduce:
- Excessive alcohol consumption (more than 1 drink per day)
- Being overweight or obese, especially after menopause
- Physical inactivity
- Hormone replacement therapy (HRT) with combined oestrogen and progestogen
- Never having been pregnant or having first pregnancy after age 30
- Not breastfeeding
- Smoking

Understanding Breast Cancer Stages at a Glance
Breast cancer is classified into stages based on tumour size, lymph node involvement, and whether it has spread. The earlier the stage, the more treatment options are available.
| Stage | Description | Tumour Size | 5-Year Survival Rate | Common Treatment |
|---|---|---|---|---|
| Stage 0 (DCIS) | Cancer cells confined within milk ducts; non-invasive | Microscopic | ~99% | Lumpectomy ± radiation |
| Stage I | Small tumour; no or minimal lymph node involvement | ≤ 2 cm | ~99% | Surgery + hormone therapy |
| Stage II | Tumour larger or nearby lymph nodes involved | 2–5 cm | ~86% | Surgery + chemotherapy |
| Stage III | Locally advanced; spread to more lymph nodes or nearby tissues | > 5 cm | ~57–86% | Neoadjuvant chemo + surgery + radiation |
| Stage IV | Metastatic; spread to bones, lungs, liver, or brain | Any size | ~28% | Systemic therapy (targeted/hormonal/chemo) |
✦
Screening and Diagnosis: What Tests Are Available?
Recommended Screening Schedule
| Age Group | Recommended Screening | Frequency |
|---|---|---|
| 20–39 years | Clinical breast exam + monthly BSE | Every 1–3 years |
| 40–49 years | Mammogram + clinical exam | Annually (discuss with doctor) |
| 50–74 years | Digital mammogram | Every 1–2 years |
| High-risk (any age) | MRI + mammogram | Annually from age 30 |
| BRCA mutation carriers | MRI + mammogram alternating every 6 months | From age 25–30 |
Diagnostic Tests Your Doctor May Order
- Mammogram — Low-dose X-ray; the gold-standard screening tool for women over 40
- Ultrasound — Helps differentiate between solid tumours and fluid-filled cysts; useful for younger women with denser breast tissue
- MRI (Magnetic Resonance Imaging) — More sensitive than mammogram; recommended for high-risk women
- Core Needle Biopsy — Removes a small tissue sample for lab analysis; the only definitive way to diagnose cancer
- Fine Needle Aspiration (FNA) — Used to sample fluid from a cyst or cells from a lump
- Genetic Testing (BRCA1/BRCA2) — Recommended if there is a strong family history
- PET-CT Scan — Used to check if cancer has spread beyond the breast

Modern Breast Cancer Treatment Options at Narayana Hospitals
Treatment depends on the type, stage, and biology of the cancer, as well as the patient's overall health and personal preferences. At Narayana Hospitals, our multidisciplinary oncology team personalises every treatment plan.
Surgical Options
- Lumpectomy (Breast-Conserving Surgery) — Removes only the tumour and a margin of surrounding tissue
- Mastectomy — Removes one or both breasts; may be recommended for larger tumours or genetic high-risk
- Sentinel Lymph Node Biopsy — Tests whether cancer has spread to lymph nodes without removing all of them
- Breast Reconstruction — Restores breast appearance after mastectomy; can be done simultaneously or later
Non-Surgical (Systemic) Treatments
- Chemotherapy — Drugs that kill fast-growing cancer cells; given before or after surgery
- Radiation Therapy — High-energy beams target residual cancer cells after lumpectomy
- Hormone Therapy — Blocks oestrogen in hormone-receptor-positive cancers (e.g., Tamoxifen, Aromatase inhibitors)
- Targeted Therapy — Attacks specific cancer cell proteins (e.g., Herceptin for HER2+ cancers)
- Immunotherapy — Helps your immune system recognise and destroy cancer cells

Can You Reduce Your Risk? Breast Cancer Prevention Tips
While not all breast cancers can be prevented, research shows that lifestyle changes can meaningfully reduce your risk. Here's what experts recommend:
- Maintain a healthy body weight throughout life, especially after menopause
- Exercise regularly — aim for at least 150 minutes of moderate activity per week
- Limit alcohol intake to no more than one drink per day; ideally avoid it altogether
- Breastfeed your baby if possible — longer duration may offer greater protection
- Avoid or limit postmenopausal hormone replacement therapy (HRT)
- Quit smoking — tobacco use is linked to higher breast cancer risk
- Discuss risk-reducing medications (chemoprevention) with your doctor if you are at high risk
- Attend all recommended screening appointments — early detection remains the most powerful tool

Frequently Asked Questions (FAQs)
What is the most common first sign of breast cancer? +
The most common first sign is a painless lump or thickened area in the breast or armpit. However, breast cancer can also first appear as skin dimpling, nipple changes, or unexplained asymmetry — sometimes with no lump at all. This is why regular self-exams and mammograms are essential even when you feel fine.
At what age should I start breast cancer screening? +
Women at average risk should begin annual mammogram screening at age 40–45. Clinical breast exams should start in your 20s. If you have a family history of breast cancer, carry BRCA gene mutations, or have other high-risk factors, your doctor may recommend starting MRI and mammogram screening as early as age 25–30.
Can breast cancer develop without a lump? +
Yes. Inflammatory breast cancer (IBC), for example, often presents without a distinct lump. Instead, you may notice redness, warmth, rapid swelling, or an orange-peel texture to the skin. DCIS (ductal carcinoma in situ) is frequently found only on a mammogram, with no physical symptoms. This is why imaging-based screening matters even when there's nothing you can feel.
Is breast pain always a sign of cancer? +
No. Most breast pain (mastalgia) is benign and related to hormonal changes, fibrocystic changes, or musculoskeletal issues. However, persistent pain in one specific area that doesn't fluctuate with your menstrual cycle, or pain accompanied by a lump or skin changes, should always be evaluated by a doctor.
Can men get breast cancer? +
Yes. While rare (accounting for about 1% of all breast cancers), men can and do develop breast cancer. Signs to watch for include a lump under the nipple, nipple discharge, nipple inversion, or skin changes around the chest. Men with BRCA2 gene mutations or a strong family history are at higher risk and should discuss screening with their doctor.
How accurate is a mammogram? +
Digital mammograms detect about 87% of breast cancers in average-risk women. 3D mammography (tomosynthesis) improves detection rates further, especially in women with dense breasts. No test is 100% accurate — a normal mammogram doesn't rule out cancer if you notice any new symptoms. Combine mammograms with regular self-exams and clinical exams for the best protection.
Does breastfeeding reduce breast cancer risk? +
Yes. Studies consistently show that breastfeeding — particularly for 12 months or more in total — is associated with a modest reduction in breast cancer risk. The longer you breastfeed, the greater the protective effect. The exact mechanism isn't fully understood, but hormonal changes during lactation may play a role.
What should I do if I find a lump? +
Don't panic — the majority of lumps are benign — but do see a doctor within 1–2 weeks. Do not wait to see if it disappears on its own. Your doctor will take a history, perform a clinical exam, and likely order an ultrasound or mammogram. If necessary, a biopsy will be performed to determine if the lump is cancerous. Early evaluation is always the right decision.
