Breast cancer can spread to other parts of the body, so try to schedule yearly mammograms and go in for a check-up as soon as you spot any symptoms.You may experience breast changes that are not related to cancer. Your healthcare provider can perform diagnostic tests and answer any questions or concerns you may have. Breast cancer is a condition that occurs when cells in the breast become abnormal and begin to grow uncontrollably. These cancerous cells can start to grow in the breast lobes that produce milk or in the ducts that carry milk to the nipple. In rare cases, the cancer starts under the skin of the breast through the bloodstream or lymphatic system (a network throughout the body that consists of the lymph, lymph nodes, and vessels). Once a diagnosis of breast cancer is made, it is given a stage, from 0 to 4, based on how advanced the cancer is. The higher the number, the more the cancer has progressed. It is common for people with breast cancer to not experience symptoms. This is why it is so important to be aware of breast cancer symptoms, have routine mammogram screenings (X-rays used to examine the breast), and speak to a healthcare provider if you notice any of these warning signs. Breast Cancer Screening Guidelines Breast Cancer Screening Guidelines: As of May 2023, the U.S. Preventative Services Task Force (USPSTF) recommends that cisgender women and people assigned female at birth get mammograms every two years beginning at age 40. This is 10 years earlier than the current guidelines. More research is needed on whether people with dense breasts should have additional screenings as well as the potential benefits and risks of screening people older than 75. Breast Lumps As cancer cells continue to grow, they can form a mass, or tumor in the breast. This is commonly referred to as a breast lump. While breast lumps are a more common sign of breast cancer, most lumps that occur in the breast are not cancerous (benign). Cancerous breast lumps can be soft or hard and painless or tender. Most cancerous breast lumps tend to have one or more of the following: Shaped irregularly with rough edgesA “pebbly” surfaceHard to the touchStable and will likely not move during a breast examSkin with a different appearance or texture than the rest of the breast Lumps can appear on the breast, near the nipple, or under the armpit. However, a cancerous lump most often occurs in the upper-outer section of the breast, close to the armpit. What Causes Breast Cancer? Risk Factors to Know Skin Changes The presence of breast cancer can cause a variety of skin changes on the breast. These changes may include: Thickening: The skin around your breast thickens or becomes swollen. Dimpling: The skin starts to dimple and looks like the texture of an orange. Redness: The skin becomes inflamed. If you have a lighter skin tone, the redness may appear pink. If you have a darker skin tone, the redness can look dark red or maroon. Rash: Arash on your breast makes your skin dry, rough, or flaky. Puckering or tethering: Your skin tissue may be pulled inward, causing your skin to look dented. Nipple Changes As breast cancer spreads, you may notice changes to your nipple. Some of these changes may include: Discharge: Your nipple can produce a liquid that is not breast milk. The appearance of the liquid can vary between milky and water, thick and thin, and brown or clear. In some cases, the discharge may have blood.Inversion: Your nipple may turn inward and appear inverted.Dryness: Your areola (the area around your nipple) can look dry or flaky. Breast Shape and Size While changes in the shape and size of your breasts can be normal as you age, sudden changes to your breasts may be a warning sign of breast cancer. You may notice your breasts suddenly swell up or shrink in size. While it is normal for breasts to naturally look a little different from one another, the symmetry of your breasts may also change. You may want to notify your healthcare provider if you notice significant changes to the appearance of the size and shape of your breasts. Symptoms for Metastatic Breast Cancer Metastatic breast cancer occurs when the cancer has metastasized or spread beyond the breast tissue and into other areas of the body. This commonly occurs in stage 4 of breast cancer. If you are in this stage, some additional symptoms you may have include: Chest, joint, or bone painNumbness in your bodyHeadaches or dizzinessVision changesVomiting or nausea Chronic or dry coughFatigueLoss of appetite Unintentional weight loss What Is the Survival Rate for Metastatic Breast Cancer? Breast Cancer Symptoms in Males Breast cancer primarily affects people assigned female at birth. Those who are assigned male at birth may also receive a breast cancer diagnosis, although it is rare (less than 1% of all breast cancer cases). Most breast cancer symptoms between males and females are similar. However, males do not usually experience changes in the size and shape of their breasts. This is because males generally have less estrogen—and estrogen causes the breasts to grow and change in size. When to See a Healthcare Provider If you notice any changes to your breasts and experience any of the symptoms above, make an appointment with your healthcare provider. This is especially true if you are over age 40, as you are more likely to develop breast cancer after this age. Getting tested can help you get an early diagnosis and figure out a treatment plan, if necessary. At your appointment, your healthcare provider may perform various tests such as a mammogram, ultrasound (non-invasive medical imaging), or biopsy (taking and examining a small sample of breast tissue). They may also ask you about your family history, previous breast surgeries or implants, and medications you are currently taking. Visiting a clinic or hospital can make some people nervous. It is OK to take a loved one to your appointment if you prefer. Living With Breast Cancer During and After Treatment Was this page helpful? Thanks for your feedback! Tell us why!
