Understanding Underarm Lumps and Breast Cancer
Worried about an underarm lump? Understand the common, benign causes of armpit lumps and learn when they might indicate breast cancer. Discover key signs to watch for and why prompt medical evaluation is crucial for peace of mind.
Introduction
Finding a lump under your arm can be a scary experience, but it’s important to remember that not all lumps are cancerous. Many underarm lumps are harmless and caused by infections, swollen lymph nodes, or cysts. However, since the underarm area is close to the breast, it’s essential to be aware of the possible connection to breast cancer.
This article will help you understand the causes of underarm lumps, when to be concerned, and what steps to take next—all in simple, easy to understand language.
What Causes Underarm Lumps?
Underarm lumps can develop for various reasons, including:
1. Swollen Lymph Nodes
The lymph nodes in your armpit help fight infections. If you have a cold, flu, or an infection in your arm or breast, these nodes may swell temporarily.
2. Infections
Bacterial or viral infections (like boils or abscesses) can cause lumps. These are often painful and may be accompanied by redness or warmth.
3. Cysts or Lipomas
Cysts – Fluidfilled sacs that are usually harmless.
Lipomas – Soft, fatty lumps that move easily when touched.
4. Breast Cancer-Related Lumps
Sometimes, breast cancer can spread to the lymph nodes in the armpit, causing a hard, painless lump. This is why any persistent lump should be checked by a doctor.

When Should You Be Concerned?
While most underarm lumps are not cancerous, certain signs should prompt you to see a doctor:
The lump is hard and doesn’t move when touched.
It doesn’t go away after a few weeks.
You notice other symptoms like:
Breast lump or thickening
Nipple discharge (especially if bloody)
Changes in breast shape or skin texture (dimpling, redness)
Unexplained weight loss or fatigue
If you experience any of these, don’t panic—but do schedule a checkup. Early detection of breast cancer greatly improves treatment success.
How Are Underarm Lumps Diagnosed?
Your doctor may perform the following tests:
Physical Exam – Checking the lump’s size, texture, and mobility.
Ultrasound or Mammogram – Imaging tests to see if the lump is solid or fluidfilled.
Biopsy – Taking a small tissue sample to check for cancer cells.
Blood Tests – To rule out infections or other conditions.
What If It’s Related to Breast Cancer?
If an underarm lump is linked to breast cancer, early treatment is key. Treatment options depend on the cancer stage but may include:
Surgery – Removing the tumor or affected lymph nodes.
Radiation or Chemotherapy – To destroy cancer cells.
Hormone Therapy – If the cancer is hormone sensitive.
The good news is that breast cancer is highly treatable when caught early.
How Can You Reduce Your Risk?
While not all breast cancer can be prevented, these steps can help lower your risk:
Perform Monthly SelfExams – Check your breasts and underarms for any changes.
Get Regular Screenings – Women over 40 should have mammograms as recommended.
Maintain a Healthy Lifestyle – Eat a balanced diet, exercise, and limit alcohol.
Know Your Family History – If breast cancer runs in your family, discuss genetic testing with your doctor.
When to See a Doctor?
If you notice a lump that:
Doesn’t go away in 23 weeks
Feels hard or irregular
Is accompanied by other breast changes
Don’t wait—consult a doctor. Early evaluation can provide peace of mind or ensure timely treatment if needed.
