Mastalgia (Breast Pain): Understanding Causes, Symptoms, and Treatment
Comprehensive guide to understanding breast pain, its causes, diagnosis, and how to manage mastalgia effectively.
Breast pain, medically known as mastalgia, is a common concern for women of all ages. While often benign, it can cause significant anxiety and impact daily activities. Understanding the underlying causes, recognizing when to seek medical evaluation, and knowing the available management strategies are vital for maintaining breast health and overall well-being.
What is Mastalgia?
Mastalgia refers to any pain, tenderness, or discomfort in the breast tissue. It is one of the most frequent breast symptoms seen in clinical practice, affecting up to 70% of women at some point in their lives. The pain may be mild or severe, intermittent or constant, and can occasionally radiate to the arm or chest wall. While breast pain is seldom related to breast cancer, its presence warrants a careful evaluation to rule out more serious conditions.
Types of Breast Pain
Breast pain is broadly categorized based on its relationship to the menstrual cycle and the underlying cause. The three main types include:
- Cyclical Breast Pain (Cyclic Mastalgia): Typically linked to hormonal fluctuations during the menstrual cycle, affecting women of reproductive age.
- Noncyclical Breast Pain (Noncyclic Mastalgia): Unrelated to the menstrual cycle. It often affects women aged 40 and above and may be caused by breast cysts, trauma, or other breast pathology.
- Extramammary (Referred) Pain: Originates outside the breast, such as from the muscles, ribs, or other body systems, but is perceived as breast pain.
Cyclical Mastalgia
Cyclical breast pain is the most common form, affecting about two-thirds of women with mastalgia. Key characteristics include:
- Closely tied to the menstrual cycle, peaking during the luteal phase (one to two weeks before menstruation) and resolving with the onset of menses
- Often described as a dull, aching, or heaviness in both breasts (bilateral)
- More noticeable in younger, premenopausal women
- May vary in intensity month-to-month
Noncyclical Mastalgia
Noncyclical breast pain is less common but often more concerning when it occurs. Its features include:
- No relationship with the menstrual cycle
- Can be constant or intermittent
- Tends to be localized to one area or one breast (unilateral)
- Seen more frequently in women aged 40 or above
- Can be linked to benign breast conditions such as cysts, infections, injury, or after breast surgery
Extramammary (Referred) Pain
This pain is felt in the breast but originates from non-breast sources, such as:
- Musculoskeletal disorders (e.g., costochondritis, arthritis)
- Chest wall trauma
- Referred pain from cardiac or gastrointestinal issues
Symptoms and How Mastalgia Feels
Breast pain can present in various ways, including:
- Aching, stabbing, or burning sensations
- Heaviness, tightness, or fullness in the breasts
- Pain that may radiate to the upper chest, armpit, or arm
- Discomfort that ranges from mild nuisance to severe, daily life-disrupting pain
- Pain location may be diffuse (spread across the breast) or well-localized
It is common for pain to worsen with movement, physical activity, or certain postures, particularly in women with large breasts or after strenuous exercise.

Who Gets Mastalgia?
While any woman can experience breast pain, certain groups are more commonly affected:
- Women aged 30 to 50 years
- Premenopausal and perimenopausal women
- Those with a family history of benign breast disease
- Women on hormone therapy, oral contraceptives, or those experiencing hormonal fluctuations (pregnancy, menopause, puberty)
What Causes Breast Pain?
Causes of breast pain are diverse and not always clearly identified. Common causes encompass:
- Hormonal fluctuations related to the menstrual cycle (estrogen and progesterone changes)
- Breast cysts
- Pregnancy and breastfeeding (milk production, engorgement, mastitis)
- Injury or trauma to the breast
- Poorly fitting bras
- Certain medications (e.g., hormonal therapy, some antidepressants)
- Breast surgery or previous procedures
- Large breast size (macromastia), leading to extra strain on chest wall tissues
- Musculoskeletal pain or costochondritis
- Referred pain from other conditions (shingles, gallbladder, cardiac causes)
Risk Factors Associated with Mastalgia
Several factors can increase the risk or severity of breast pain:
- Premenopausal status and cyclical hormonal changes
- Hormone-based medications (contraceptives, hormone replacement therapy)
- Obesity or large breast size
- Stress and anxiety
- Poor posture or musculoskeletal strain
- History of breast trauma, cysts, or benign breast conditions
Does Breast Pain Indicate Breast Cancer?
One of the greatest concerns about mastalgia is its relationship to breast cancer. Fortunately, breast pain is rarely a sign of cancer. Only 2-7% of women who present with breast pain are diagnosed with breast cancer. However, certain features warrant more attention:
- Persistent, noncyclical, and well-localized pain
- Pain in postmenopausal women
- Associated symptoms such as a palpable lump, skin changes, or nipple discharge
If these features are present, further diagnostic evaluation by a healthcare provider is advised.
How Is Mastalgia Diagnosed?
The approach to diagnosis begins with a thorough medical history and physical exam. Critical questions and aspects typically addressed include:
- Nature, onset, and duration of pain
- Cyclical relationship to menstruation
- Location (unilateral or bilateral, focal or diffuse)
- Presence of other symptoms (lump, redness, fever, nipple changes)
- Current medications and hormonal therapies
- Family or personal history of breast disease or cancer
If the clinical exam is normal and the woman is under 30, reassurance and follow-up is often sufficient. If any suspicious findings are detected, or the woman is over 30 or postmenopausal, further evaluation may include:
- Mammography
- Breast ultrasound
- Magnetic resonance imaging (MRI) when indicated
- Additional targeted tests for extramammary sources if suspected
When Should You Seek Medical Attention?
Most breast pain is harmless and resolves on its own. However, consult a healthcare professional if you experience:
- Persistent pain lasting more than two weeks
- Pain localized to one area (especially if new or noncyclical)
- Associated breast lump
- Nipple discharge (particularly blood-stained)
- Skin changes (dimpling, redness, thickening)
- Signs of infection (fever, swelling, redness)
- Pain that interferes with daily functioning
How Is Mastalgia Treated?
Most cases of mastalgia can be managed with noninvasive measures. Treatment depends on the type, underlying cause, and severity of the pain.
- Reassurance and Education: Understanding that most breast pain is benign relieves anxiety for many women.
- Supportive Bras: Properly fitted, supportive bras can reduce motion-related pain.
- Lifestyle Modifications: Reducing caffeine, dietary fat, and improving posture may help, although evidence is limited.
- Pain Medications: Topical nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac gel, or, if necessary, oral analgesicts.
- Addressing Causative Factors: Managing cysts, infections, or removing inciting medications when appropriate.
- Hormonal Therapy: In severe, persistent cases, medications like tamoxifen or danazol may be considered, though these carry significant potential side effects and are reserved for refractory cases.
- Alternative Remedies: Evening primrose oil and vitamin E have been used by some women, but scientific support for their effectiveness is limited.
Table: Common Mastalgia Treatments and Their Use
| Treatment | Usage | Considerations |
|---|---|---|
| Supportive Bra | Daily comfort | Proper fit essential |
| Topical NSAIDs | Localized/application to affected area | Minimal systemic side effects |
| Oral Analgesics | Short-term/severe pain | Use as needed |
| Hormonal Therapy (Tamoxifen, Danazol) | Severe/refractory pain | Monitor for side effects, given under medical supervision |
| Lifestyle Modifications | Adjunctive support | Evidence variable |
Can Mastalgia Be Prevented?
While not all cases can be prevented, some strategies may lower the risk or severity of breast pain:
- Wearing a supportive, well-fitting bra during the day and during exercise
- Tracking menstrual cycles to anticipate periods of discomfort
- Maintaining a healthy weight
- Managing stress through exercise, mindfulness, or relaxation techniques
- Discussing the risk of medication-induced mastalgia with a healthcare provider before starting new hormonal therapies
These steps may limit or reduce symptoms, particularly in women prone to cyclical mastalgia.
Living with Breast Pain
Though sometimes distressing, breast pain is rarely dangerous. Self-care, reassurance, and regular check-ups foster confidence and comfort. If symptoms change, worsen, or are accompanied by concerning signs, timely consultation with a healthcare professional ensures appropriate care and peace of mind.
Frequently Asked Questions (FAQs)
