Breast cancer does not always cause noticeable symptoms in its earliest stages. However, the widespread use of routine screening tests has greatly increased the likelihood of early detection. For instance, self-screening can identify tumors that are large enough to be felt, or a low-dose X-ray breast examination (mammogram) may even reveal a tumor long before it grows large enough to be seen or felt. Because there are generally more treatment options available for early-stage breast cancer, early detection is key to achieving the best possible outcome and quality of life.

Although mammograms are highly effective, they do not detect every incidence of cancer. Therefore, it is important for everyone to learn about breast cancer symptoms and to promptly see a physician if you notice anything unusual about your breasts or overall health.

Early warning signs and early symptoms of breast cancer

The most common early symptom of breast cancer is a new lump in the breast. Cancerous lumps are usually painless, hard and irregularly shaped, but they can also be tender, soft and rounded. 

Keep in mind that breast changes are common, and the majority are not caused by cancer. For instance, many women experience changes in their breasts before or during their menstrual periods, during pregnancy, as they approach menopause, while using hormone therapy and after menopause. Additionally, normal breast tissue may feel lumpy and many breast lumps are benign (noncancerous).

Common breast cancer signs and symptoms

Some of the most common symptoms associated with breast cancer include:

  • A lump or thickening in the breast or underarm region
  • Swelling of all or part of the breast
  • An unexplained change in the size or shape of one or both breasts
  • A recent onset of breast asymmetry (one breast has a different size, shape or position than the other)
  • A newly inverted nipple
  • Nipple discharge (other than breast milk)
  • Unusual nipple tenderness
  • Dimpling or puckering on the surface of the breast
  • Peeling, crusting, scaling or flaking of the breast skin or the pigmented area surrounding the nipple (the areola)
  • Redness, warmth, thickness or pitting of the breast skin (similar to an orange peel)
  • Itching or skin irritation on one or both breasts
  • Breast pain
  • Swollen lymph nodes under the arms or near the collar bones

The presence of one or more breast cancer symptoms does not conclusively indicate cancer, and it’s impossible to know for sure whether a breast lump is benign or malignant (cancerous) without a professional medical evaluation. If you discover a lump or another change in one or both of your breasts—even if your most recent mammogram produced a normal result—you should make an appointment with a physician for an evaluation as soon as possible.

What does breast cancer feel like?

You may not experience any symptoms at all with breast cancer. But again, the most common symptom is a lump in the breast, which can feel different depending on the type of breast cancer and the size of the tumor. You might also feel pain in your breasts, nipple tenderness, and unusual discharge from your nipple.

Breast cancer doesn’t always cause visible symptoms, but you may see some of the changes listed above, such as newly asymmetrical breasts, a newly inverted nipple, dimpled or pitted skin, redness, peeling, crusting and so forth.
