What Is Breast Cancer?
Breast cancer develops when cells in the breast begin to grow out of control, eventually forming a tumor. Most tumors originate in the milk ducts (ductal carcinoma) or the glandular tissue (lobular carcinoma) [1].
Risk factors are complex and include non-modifiable factors like genetics (BRCA1/2 mutations), increasing age, and dense breast tissue, alongside modifiable factors like lifestyle and hormonal exposures. Understanding these risks, while important, is secondary to recognizing symptoms, as knowing what to look for and when to consult a doctor is key to catching the disease when it is most treatable.Common Signs and Symptoms of Breast Cancer
Symptoms can vary widely among individuals. If you notice any of these signs, particularly if they are new or persistent, a consultation with a healthcare provider is warranted [2, 3].1. Lump or Mass
- A new lump or mass in the breast or underarm (axilla). This is the most common symptom.
- The lump may feel hard, often painless, and have irregular edges, though some benign lumps can feel similar.
2. Changes in Size and Shape
- A noticeable change in the size or shape of one breast.
- Swelling of all or part of a breast, even if no distinct lump is felt.
3. Skin Changes
- Dimpling, puckering, or thickening of the breast skin. This can resemble the surface of an orange peel, a condition known as peau d’orange [2].
- Redness, scaling, or flaking of the skin around the nipple or breast.
4. Nipple Changes and Discharge
- Nipple retraction (turning inward) or inversion.
- Nipple discharge, particularly bloody, clear, or spontaneous (occurring without squeezing) in non-lactating women.
- Pain or tenderness in the nipple area.
5. Pain
- While breast cancer is often painless, unexplained or persistent breast pain (mastalgia) or discomfort that lasts for a long time in one area should not be ignored.
Symptoms by Disease Subtype and Stage
The presentation of breast cancer can vary, especially with aggressive subtypes:- Triple-Negative Breast Cancer (TNBC):
This subtype is characterized by the absence of estrogen, progesterone, and HER2 receptors. TNBC tends to be more aggressive and fast-growing and is more common in younger women or those with a BRCA1 gene variant [4]. Symptoms are generally the same (lump, skin changes) but may appear or progress more rapidly.
- Early Stage (Stage 0 or I):
At this stage, cancer is often non-palpable and is frequently detected solely through routine mammography. If a lump is present, it is usually very small (≤2 cm) and not involving the lymph nodes [5].
- Advanced Stage (Stage III):
Symptoms often become more pronounced, involving larger, potentially fixed lumps (stuck to the skin or chest wall), visible skin dimpling or ulceration, and significant swelling of the lymph nodes under the arm.

Signs of Breast Cancer in Men
Though breast cancer in men is infrequent, accounting for less than 1% of all cases, men should be equally vigilant, as the symptoms are similar and often diagnosed at a later stage due to lack of awareness [6].
- A painless lump or thickening behind the nipple or in the chest area.
- Changes to the skin over the breast, such as dimpling, scaling, or redness.
- Nipple changes, particularly inversion or discharge.
Why Early Detection is Crucial
Finding breast cancer early, before it has had a chance to spread (metastasize), dramatically increases the chances of successful treatment and long-term survival.
- Survival Rates:
Localized breast cancer (confined to the breast) has a 5-year relative survival rate of approximately 99% [7]. This rate drops significantly once the disease has spread regionally (to lymph nodes) or distantly (to other organs).
- Treatment Options:
Early detection allows doctors to choose less aggressive or less invasive treatments, such as breast-conserving surgery (lumpectomy) rather than mastectomy, and potentially reduced needs for extensive chemotherapy.
Access to the right cancer care facilities and advanced diagnostic services plays a critical role in early detection and timely treatment. Below are specialised centres offering comprehensive cancer care and PET/CT imaging support:
Monitoring Your Breast Health
Routine screening and awareness are the two most powerful tools for early detection.- Breast Awareness:
While formal monthly self-exams are no longer universally recommended, it is essential for all individuals to be familiar with the normal look and feel of their breasts. Report any new or persistent changes—lumps, dimpling, or nipple discharge—to your doctor immediately.
- Clinical Breast Exams (CBEs):
An exam performed by a healthcare professional as part of a routine checkup.
- Mammography:
Routine mammograms are the gold standard for screening and are recommended for women over 40 or those in high-risk groups, following specific clinical guidelines (American Cancer Society, 2023) [8].
If you notice any concerning symptoms, whether or not you are due for a routine screening, seek prompt medical evaluation. It is always better to rule out cancer than to delay potentially life-saving diagnosis.
Conclusion
Empower yourself by knowing the key signs and symptoms of breast cancer: new lumps, persistent skin or nipple changes, and unexplained pain. Finding the disease early, when it is localized, greatly increases the chances of survival and allows for potentially less intensive treatment. Pay attention to subtle changes, and do not hesitate to consult a doctor, as your proactive attention is the best defense against breast cancer.

Frequently Asked Questions (FAQ’s)
Blog-Key Breast Cancer Symptoms and the Critical Importance of Early Detection
Is Every Breast Lump Cancerous?
No. Most breast lumps are benign (non-cancerous). Common benign causes include fibroadenomas (solid, movable, non-cancerous tumors), cysts (fluid-filled sacs), or changes related to the menstrual cycle. However, only a doctor can determine the nature of a lump, typically through diagnostic imaging (ultrasound/mammogram) and, if necessary, a biopsy. All new lumps must be evaluated.
Does Breast Pain Always Mean I Have Breast Cancer?
No. Breast pain (mastalgia) is very common and is usually related to hormonal fluctuations (especially before a menstrual period), breast cysts, or external factors like ill-fitting bras or musculoskeletal pain. Cancer is usually painless. Nonetheless, if breast pain is persistent, localized to one spot, and not clearly linked to hormonal cycles, it should be checked by a physician.
When Should Women Start Getting Routine Mammograms?
The age for starting routine screening varies slightly by organization, but the American Cancer Society recommends that women at average risk have the option to start screening with yearly mammograms between ages 40 and 44, and should start annual screening by age 45. Screening frequency may change to every two years after age 55. Women with a high-risk history may need to start earlier and may require supplemental screening like MRI. Consult your doctor for personalized advice.
What Is The Difference Between An Early Sign And A Late Sign?
Early signs often involve subtle changes noticed through self-awareness or, most commonly, are only visible on a mammogram (Stage 0 or I) before a lump is felt. Late signs (typically Stage III or IV) indicate more advanced disease and may include a large, fixed lump, visible skin ulceration, or swelling in the armpit due to extensive lymph node involvement. The goal of screening is to detect the disease at the earliest, asymptomatic stage.
