Key Takeaways
- Breast cancer involves abnormal cell growth in breast tissue and can spread beyond the breast.
- It can affect people of any age and sex, though it is more common in women.
- Early detection through symptom awareness and screening is associated with better treatment options and outcomes.
- Many breast changes are not cancer, but medical evaluation is required to determine the cause.
- Emergency care is appropriate only for severe or urgent symptoms.
What Is Breast Cancer?
Breast cancer is a condition in which abnormal cells grow in breast tissue and can spread to other parts of the body. It most commonly starts in the milk ducts or lobules but can spread beyond the breast over time.
Breast cancer is not a single disease; it includes multiple types and subtypes that behave differently and may require different treatments. The specific type is determined through diagnostic testing after an abnormal finding.
Although breast cancer occurs far more often in women, it can also develop in men.
Early Detection: Symptoms and Screening
Early detection means identifying breast cancer before it causes serious health problems. This can happen in two main ways.
Screening
Screening uses tests—most commonly mammograms—to look for breast cancer in people who do not have symptoms. Screening can detect cancer before it can be felt or noticed and is a key part of early detection.
Symptoms
Some people notice changes in their breasts that lead them to seek medical care. Not all breast cancers cause symptoms in the early stages, which is why screening remains important even when no changes are felt.
Both symptom awareness and appropriate screening play complementary roles in early detection.
Common Symptoms and Warning Signs
Breast cancer symptoms vary from person to person. Possible warning signs include:
Lumps or Masses
- A new lump or thickening in the breast or underarm
- Lumps may feel hard or soft
- Many cancerous lumps are painless, but pain can occur
Changes in Breast Size or Shape
- Swelling or thickening of part of the breast
- One breast appearing noticeably different from the other
Skin Changes
- Dimpling or puckering of the skin
- Redness or inflammation
- Skin that looks textured, sometimes described as resembling an “orange peel”
Nipple Changes
- Nipple turning inward
- Discharge that is not breast milk
- Scaling, redness, or thickening of the nipple or surrounding skin
Breast or Nipple Pain
- Persistent pain in one area of the breast
- Pain alone is usually not caused by cancer, but unexplained or ongoing pain should be evaluated
Many of these symptoms can also be caused by non-cancerous conditions. Medical evaluation is needed to determine the cause.
Less Common Presentations
Some types of breast cancer present differently and may not involve a distinct lump.
Inflammatory Breast Cancer
- Rapid swelling, redness, or warmth of the breast
- Skin thickening or ridging
- Symptoms can develop quickly and may resemble an infection
Paget Disease of the Breast
- Eczema-like changes of the nipple or areola
- Itching, burning, or flaking skin that does not heal
Breast Cancer in Men
- Lump or thickening in breast tissue
- Changes to the nipple or surrounding skin
Breast cancer in men is rare, but symptoms should not be ignored.
Breast Self-Awareness
Being familiar with how your breasts normally look and feel can help you notice changes.
What Is “Normal”?
Normal breast texture and sensitivity vary between individuals and can change with age, hormones, or menstrual cycles.
Breast Self-Exams
Self-exams may help people recognize changes. Common guidance includes:
- Looking at the breasts for visual changes
- Using the fingers to feel breast tissue and the underarm area
- Covering the entire breast using a consistent pattern
Self-exams are intended to increase awareness and do not replace screening tests. Recommendations about how often to perform them vary and should be discussed with a healthcare professional.
When to See a Doctor
You should schedule medical evaluation if you notice:
- A new lump, thickening, or swelling
- Persistent breast or nipple pain
- Skin or nipple changes that do not resolve
- Nipple discharge that is not breast milk
A clinician may perform a physical exam and recommend imaging tests or other studies. Many breast changes are not cancer, but only proper medical evaluation can determine the cause.
Emergency Symptoms That Require Immediate Care
Seek emergency medical attention if you experience:
- Severe chest pain or trouble breathing
- Sudden breast swelling with fever and severe pain
- Signs of a severe allergic reaction
- Serious complications after a medical procedure or treatment
These situations require immediate evaluation, regardless of the underlying cause.
Choosing the Right Care Setting
| Situation | Appropriate Care |
| Mild or ongoing breast changes | Routine medical visit |
| New lump or persistent symptoms | Medical evaluation with a clinician |
| Severe pain, fever, breathing difficulty | Emergency care |
Emergency departments can evaluate urgent symptoms and rule out immediate threats. Confirming breast cancer usually requires outpatient imaging and biopsy.
How Breast Cancer Is Diagnosed
After an abnormal finding:
- A clinical breast exam is typically performed
- Imaging tests such as mammography or ultrasound may be ordered
- A biopsy may be needed to determine whether cancer cells are present
If cancer is diagnosed, staging describes how far it has spread. Staging is determined using imaging and pathology results.
Treatment Overview
Breast cancer treatment depends on the cancer type and stage and may include:
- Surgery
- Radiation therapy
- Systemic treatments such as chemotherapy or hormone therapy
Treatment plans are individualized and discussed between patients and their care teams.
Risk Factors and Prevention
Certain factors increase breast cancer risk, including age, family history, and genetic factors. Not all cases can be prevented. Following recommended screening and maintaining overall health may help reduce risk or improve outcomes through earlier detection.
Frequently Asked Questions
Can the emergency room check for breast cancer?
Emergency departments can evaluate urgent symptoms and rule out immediate threats. Confirming breast cancer usually requires outpatient imaging and biopsy.
Should I go to the ER for breast pain?
Emergency care is appropriate if breast pain is severe, sudden, or accompanied by symptoms such as fever, chest pain, or difficulty breathing.
Can urgent care evaluate a breast lump?
Urgent care centers may assess symptoms and refer patients for further testing, but definitive diagnosis usually requires follow-up imaging and biopsy.
Can younger people get breast cancer?
Yes. Breast cancer can occur at any age, though it is more common as people get older.
Can I go to urgent care for breast pain?
Urgent care may evaluate symptoms and recommend next steps. Severe symptoms may require emergency care. There is no high-quality evidence supporting urgent care as a setting for definitive breast cancer diagnosis.
Can the ER diagnose cancer?
Emergency departments can address urgent problems, but definitive cancer diagnosis requires imaging and biopsy performed outside the ER setting.
Can the emergency room screen for breast cancer?
There is no high-quality evidence supporting emergency rooms as a setting for routine breast cancer screening.
What are breast cancer symptoms in young women?
Breast cancer symptoms can occur at any age and are similar across age groups. There is no high-quality evidence supporting age-specific symptom differences beyond overall risk variation.
