4 typical symptoms of breast cancer

　　Breast cancer The symptoms are varied and not all of them appear or occur at the same time. The following are typical signs observed in breast cancer patients：

　　(I) Breast lumps in various locations… hospital Among breast cancer patients admitted to treatment, more than 90% present with a breast lump as their initial symptom. Patients often discover these lesions inadvertently; they are usually solitary, firm in texture, have irregular edges, and an uneven surface. Most breast cancers present as painless lumps, although in a few cases, there may be mild to severe discomfort or a stinging sensation. If the tumor invades the gland and… skin The ligaments between them cause shortening, which can result in skin depressions resembling dimples, hence the term “dimple sign.” As cancer cells block the lymphatic vessels, edema occurs, causing the skin of the breast to take on an orange-peel-like appearance, a condition also known as “peau d’orange.” Among breast lumps, it is necessary to distinguish between breast cancer and benign conditions disease To make an identification.

　　(II) Nipple discharge refers to the presence of blood, serous fluid, milk, or pus flowing from the nipples during non-pregnancy periods, or the continued discharge of milk even more than six months after breastfeeding has ceased. There are many causes of nipple discharge. Among the surgical patients admitted to the hospital, benign and malignant tumors account for 60% to 70%, while breast cancer accounts for approximately 26%. The incidence of breast cancer in cases of nipple discharge increases with age. The nature of breast cancer discharge is often bloody, serous, or watery. Most cases of thin bloody exudate are due to cancer. In about 5% of cases of breast cancer, there is bloody discharge from the nipple.

　　(III) Abnormal tumors of the nipple and areola, if located deep within the nipple or in its vicinity, can cause retraction of the nipple. If the tumor is located far from the nipple, but the large ducts within the breast are affected and become shortened as a result, this can also cause the nipple to retract or elevate. nipple Eczema Papillary carcinoma, also known as Paget’s disease of the nipple, is characterized by itching, erosion, ulceration, crusting, desquamation, and a burning sensation of the nipple skin, which may lead to nipple retraction. >>>>> What are the different types of breast pain?

　　(IV) Hidden breast cancer characterized by enlarged axillary lymph nodes, that is, breast cancer in which no lump can be felt during a physical examination, often presents initially with swollen axillary lymph nodes. In recent years, approximately 46% of breast cancer patients admitted to hospitals have axillary lymph node metastases. That is, the lymph nodes in the same axillary region become enlarged, firm in texture, scattered, and still movable at first. Over time, they will gradually fuse together and adhere to the skin and surrounding tissues, becoming fixed in place. In the late stages, metastatic lymph nodes may also be palpable above the clavicle and in the contralateral axilla.
