A lump in the breast is the most well-known sign of breast cancer. It can send a wave of panic over anyone who notices one on themselves. However, there are other symptoms of breast cancer to look out for. In a general sense, any changes to breasts shouldn’t be dismissed, such as shifts in size and shape. If you notice such differences, consult your healthcare practitioner, but don’t panic. It’s likely the symptoms are from a more benign issue, but it’s always better to have a professional clarify that. Here are some early symptoms of breast cancer everyone should know.

Early symptoms of breast cancer

Breast tumors vary depending on the individual. Some may have no symptoms at all, which is why preventative screenings are so important. The most well-known sign is a lump or node in or on the breast or armpit. However, lumps can also be from fibrocystic breast conditions and cysts, according to the CDC. Speak to a doctor if you are concerned about a node, or any of these signs:

  • General pain in or on the breast 
  • Nipple discharge (not breastmilk)
  • Enlargement in one or both breasts
  • Change of shape in one or both breasts
  • Changes in the appearance of one or both nipples
  • Swelling, redness, or other abnormalities on the skin of one or both breasts

Early symptoms of invasive breast cancer

Invasive breast cancer is the most common type of breast cancer. It occurs when cancer cells begin in the ducts or glands and then spread to the surrounding tissue. All types of breast cancer tend to have overlapping symptoms, but it can be helpful to know specific signs to point them out to a healthcare professional. 

  • Itchy or irritated breasts
  • Breasts that enlarge or change shape over a short timespan
  • A thickening or lump in the breast
  • Tenderness or warmth in the breast
  • Breast skin is red or pitted (which can resemble the textured skin of a citrus fruit)
  • Nipple skin that flakes or peels

As the cancer spreads, symptoms of invasive breast cancer may become more noticeable. These signs may include:

  • A lump or mass in the breast or armpit
  • Swelling, even if there’s no lump, in the breast or armpit
  • Pain in the breast or nipples
  • Dimpling or irritation on the skin
  • Nipples that turn inward (retract)
  • Nipple discharge
  • Skin on the breasts or nipple looks scaly, red, or thicker than usual

Symptoms of inflammatory breast cancer

Inflammatory breast cancers (IBC) are harder to diagnose because they don’t typically come with the tell-tale lump. Self-examination often doesn’t work, and they may not even be picked up during mammogram screenings. This is an aggressive form of cancer that can progress rapidly, so be mindful of its symptoms and promptly speak to your healthcare provider about any concerns. Although it doesn’t present as a lump, IBC can come with noticeable surface changes, explains City of Hope National Medical Center. These include:

  • Swollen, itchy, red, and tender breasts
  • Breast skin has a ridged or pitted texture (akin to a citrus peel)
  • One breast is notably larger than the other
  • Pain, burning, or heaviness in one breast
  • Swollen lymph nodes in the armpit or above the collarbone
  • Symptoms persist after antibiotic treatment (which rules out mastitis as a diagnosis)

Symptoms of metastatic breast cancer

Metastasis is the process by which cancer cells spread from the primary site (duct or lobule) to other parts of the body. Signs of metastatic breast cancer depend on its stage and where the cells have spread. Sometimes there are no signs at all. Here are some commonly affected body parts and their physical reactions:

  • Breast or chest wall: pain, nipple discharge, and a lump or thickening in the breast or armpit
  • Brain or spinal cord: headaches, blurred or double vision, confusion, pain, memory loss, difficulties moving or speaking, or seizures
  • Bones: pain, fractures, constipation, nausea, confusion, or fatigue
  • Liver: fatigue, nausea, yellow or itchy skin, swollen hands or feet, or an enlarged abdomen
  • Lungs: difficulty breathing, coughing, chest pain, shortness of breath, or fatigue

For reference, non-invasive breast cancer is an early form of breast cancer where the tumor is confined to the milk ducts. It’s also known as ductal carcinoma in situ (DCIS) or stage 0 cancer. It is detectable only by mammography, as it usually causes no physical symptoms. Meanwhile, lobular carcinoma in situ (LCIS) occurs when there are abnormal cells in the breast’s lobules. It has no symptoms and cannot be seen in a mammogram. Rather, it’s typically found during a breast biopsy for an unrelated reason. LCIS is not considered cancer, but it does indicate a much higher risk of breast cancer, warns Mayo Clinic.

Breast cancer symptoms in men

By definition, breast cancer is found in breast tissue, which means anyone can get it regardless of gender. Men make up about one in every 100 breast cancer cases in the United States, according to the American Cancer Society. Cleveland Clinic explains that risk factors include family history of breast cancer, having genes associated with breast cancer, high estrogen levels, radiation therapy on the chest, testicular injuries or health conditions, and being over 60 years old. In these instances, the signs include:

  • Nipple discharge or bleeding
  • Lumps or thickening in the breast
  • Redness, flaking, swelling, or dimpling on the breast or nipple
  • Pain or tenderness in the breast or armpit
  • Retracted nipple

When to see a doctor

It’s easy to read about cancer and become paranoid about having it. So remember that these symptoms could come from other conditions. Additionally, it’s normal for breasts to change, especially alongside weight fluctuations, pregnancy, breastfeeding, and other hormonal shifts. If you are concerned, speak to your healthcare practitioner about further evaluation. There’s an ongoing debate on how often people should get screened for breast cancer. The US Preventive Services Task Force recommends that women aged 40 to 74 years with an average risk for breast cancer should get screened every 2 years. The American Cancer Society recommends that women at high risk of breast cancer get tested yearly after age 30.
