What Does a Breast Cancer Lump Feel Like? Learn the Symptoms

The American Cancer Society’s (ACS) most recent guidelines recommend against breast self-exams for most women. Their decision states that self-exams haven’t shown a clear benefit, even when doctors conduct those exams. Still, some men and women will find breast cancer and be diagnosed with it as a result of a lump detected during a self-exam.

If you’re a woman, it’s important for you to be familiar with how your breasts look and check them regularly. This will help you become aware of any changes or abnormalities as they occur.

All breast lumps deserve medical attention. Unusual lumps or bumps in breast tissue are something that should be examined by a doctor. The vast majority of lumps aren’t cancerous.

What does a lump feel like?

Breast cancer lumps don’t all feel the same. Your doctor should examine any lump, whether or not it meets the most common symptoms listed below.

Most commonly, a cancerous lump in the breast:

  • is a hard mass
  • is painless
  • has irregular edges
  • is immobile (doesn’t move when pushed)
  • appears in the upper outer portion of your breast
  • grows over time

Not all cancerous lumps will meet these criteria, and a cancerous lump that has all of these traits isn’t typical. A cancerous lump may feel rounded, soft, and tender and can occur anywhere in the breast. In some cases, the lump can even be painful.

Some women also have dense, fibrous breast tissue. Feeling lumps or changes in your breasts may be more difficult if this is the case. Having dense breasts also makes it more difficult to detect breast cancer on mammograms. Despite the tougher tissue, you might still be able to identify when a change begins in your breast.

What are the other possible symptoms of breast cancer?

In addition to a lump, you may experience one or more of the following most common breast cancer symptoms:

  • swelling on part or all of your breast
  • nipple discharge (other than breast milk, if breastfeeding)
  • skin irritation or scaling
  • redness of the skin on the breast and nipples
  • a thickening of the skin on the breast and nipples
  • a nipple turning inward
  • swelling in the arm
  • swelling under the armpit
  • swelling around the collar bone

You should see your doctor if you experience any of these symptoms, with or without the presence of a lump. In many cases, these symptoms aren’t caused by cancer. Still, you and your doctor will want to do some tests to find out why it’s happening and what can be done to stop it.

What should I do if I think I have a lump?

Your body is your own, and it’s the only one you have. If you find a lump or you’re experiencing any unusual symptoms, you should seek out your doctor’s guidance. Your doctor may be able to determine from a physical exam whether your lump is likely to be cancerous. If you’re at all concerned about the new signs and symptoms, you shouldn’t be afraid to request additional testing to diagnose your lump.

What can I expect at my doctor’s appointment?

Make an appointment with your primary care doctor or gynecologist. Tell your doctor about the new spot you’ve identified and the symptoms you feel. Your doctor will likely conduct a full breast exam and may also check nearby spots, including your throat, arms, and neck. Based on what they feel, your doctor may order additional testing, such as a mammogram, ultrasound, or biopsy.

Your doctor may also suggest a period of watchful waiting. During this time, you and your doctor will continue to monitor the lump for any changes or growth. If there’s any growth, your doctor should begin testing to rule out cancer.

Be honest with your doctor about your concerns. If your personal or family history puts you at a higher risk of having breast cancer, you may want to begin with more invasive testing so you can know for sure if your breast lump is cancer or something else.

When should I see my doctor?

Breast cancer is the most common cancer diagnosed in women in the United States. Most breast lumps aren’t cancerous, however. You should visit your doctor if you see or feel anything new or unusual in your breast during a self-exam.

Despite the statistics and ACS guidelines, many women still choose to continue performing self-exams. Whether or not you choose to do self-exams, you should talk to your doctor about the appropriate age to begin screening mammograms.
