Breast cancer is often a lifelong concern for many women and men, affecting millions of Americans every year. Through Breast Cancer Care at Penn Medicine, our nationally recognized breast cancer doctors, surgeons, and nurses address every aspect of breast cancer care with compassion and expertise. As a leader in breast cancer advancements, we combine leading-edge breast cancer treatment with personalized care. Our specialized team works to ensure you have an accurate diagnosis, effective treatment, and the supportive services you need.

What is breast cancer?

Breast cancer is a disease in which the breast cells of the lobules, ducts, or surrounding connective tissue begin to grow abnormally. Rapid division of these breast cells causes the formation of a breast lump or mass that grows and, in certain cases, metastasizes (spreads) to blood vessels, lymph nodes, or other areas of the body. Although breast cancer is more common in people who were assigned female at birth, it may develop in people who were assigned male at birth as well.

Types of breast cancer and classifications

There are many types of breast cancer. Each one develops and responds to treatment differently. At Penn Medicine, we know that accurately identifying the breast cancer type is the first step in effective breast cancer treatment. Our specialized breast pathologists use their in-depth understanding of tumor characteristics to recognize all types of breast cancer.

Breast cancer symptoms

Recognizing the symptoms of breast cancer can be challenging. The signs may look different for each person and may depend on your breast cancer stage—a numerical scale from 0 to IV to represent how far your breast cancer has progressed in tumor size, spread, and location. Small, early-stage breast cancer rarely has symptoms. In those cases, screening is vital to early detection.

Breast cancer symptoms to look for include:

  • Hard, often painless, lump or mass of the breast or underarm
  • Swelling in all or part of your breast
  • Skin dimpling or puckering
  • Red, flaky, or thickened skin on your breast or nipple
  • Breast pain or heaviness
  • Nipple changes that may include pain or nipple retraction (turning inward)
  • Nipple discharge other than breast milk
  • Any change in the size or shape of your breast

Check breast cancer symptoms, changes, or concerns right away. At Penn Medicine, we rely on advanced screening and thorough evaluation to pinpoint the cause of your symptoms. Knowing what to look for between breast cancer screenings can play an important role in diagnosing breast cancer.

In some cases, breast pain or lumps may be caused by a benign (non-cancerous) issue. You may notice signs of breast cancer, but your imaging does not show a tumor. Our specialized nurse practitioners work to determine the cause of your symptoms. If needed, we can connect you with a physician or surgeon for further assessment.

Breast cancer diagnosis and testing

We believe successful cancer treatment begins with an accurate diagnosis made by a skilled pathologist. Our renowned breast cancer pathologists who will evaluate you have specific expertise on breast tissue and performing a breast biopsy—this means we can identify the unique characteristics of your cancer and get you the right treatment as soon as possible.

Your breast cancer diagnosis will identify the type of cancer you have, the stage of your breast cancer, your cancer’s HER2 status, and your cancer’s hormone receptor status.

Personalized treatment for the full range of breast cancers

After we make a diagnosis and determine which breast cancer type you have, our breast cancer oncology team works with you to develop a personalized breast cancer treatment plan. Along with standard care, we offer unique access to novel therapies and the newest treatments through our breast cancer research.

Your care plan at Penn Medicine may include:
