What are the main symptoms of breast cancer?

What are the main symptoms of breast cancer? I believe many people have this question. Breast cancer may be asymptomatic in the early stages, but as the disease progresses, it may manifest local and systemic symptoms. Let's follow the experts to learn about the symptoms of breast cancer .

1. Lump: It is the first symptom of breast cancer. According to foreign reports, most lumps are located in the upper outer quadrant, followed by the upper inner quadrant and the nipple areola area, and less in the lower part. The lumps vary in size, with 2 to 3 cm being the most common. They are mostly single, but occasionally multiple. The lumps are mostly round or oval, with unclear boundaries, generally hard nodules, and poor mobility.

2. Pain: Most breast cancer patients lack pain symptoms. Since pain rarely occurs, breast cancer is not easy to be detected early. Pain often manifests as breast tingling, distending pain or dull pain. If there is breast cystic hyperplasia around the cancer, periodic pain may also occur.

3. Breast skin changes: Breast tissue is surrounded by the superficial fascia under the skin, and the deep and superficial fascia are connected by Cooper's ligaments. Since the superficial fascia is connected to the skin, when breast cancer invades the Cooper's ligaments between the breasts and shortens them, it will pull the skin, causing the local skin to sag, like a dimple, which is called the "dimple sign". In addition, direct adhesion of the tumor to the skin may also cause this situation. The dimple sign can appear at an early stage of breast cancer and is more obvious when the affected arm moves up and down.

4. Changes in breast contour: When the tumor is large, the breast may bulge locally and enlarge. When the tumor involves the skin or chest muscles, the breast may become hard and shrink. When the patient sits upright, the affected breast may rise. This is also a symptom of breast cancer.

5. Changes in the nipple and areola: ① Nipple retraction and direction change: The nipple becomes flat, retracted, sunken, and changes direction until it is completely retracted under the areola and the nipple cannot be seen. Nipple retraction caused by breast cancer is different from congenital nipple retraction. The latter can often be pulled out by hand, while nipple retraction caused by breast cancer cannot be pulled out, and lumps can be felt under or around the sunken nipple. This is also a symptom of breast cancer.
