Breast lumps: accidentally discovered, manifested as breast tumors and nodules, you need to be vigilant and go to the hospital as soon as possible; 2. Nipple discharge: especially blood discharge, you need to be vigilant and go to the hospital as soon as possible for further examination to rule out breast cancer; 3. Breast pain: Some early breast cancer patients may experience breast pain and discomfort, especially those with breast hyperplasia or other benign diseases.

What are the types of breast cancer?

The pathological classification of breast cancer is relatively complex and is usually divided into the following types: 1. Non-permeable breast cancer: including lobular carcinoma in situ and ductal carcinoma in situ; 2. Early permeable breast cancer: including early permeable lobular carcinoma and early permeable ductal carcinoma, among which early permeable ductal carcinoma is more common in breast cancer; 3. Permeable breast cancer: including permeable non-specific breast cancer and permeable specific breast cancer. Permeable non-specific breast cancer includes permeable lobular carcinoma and permeable ductal carcinoma. Special breast cancer includes medullary carcinoma, mucinous adenocarcinoma, apocrine carcinoma, etc.; 4. Other rare breast cancers: such as inflammatory breast cancer and Paget's disease.

Treatment options for breast cancer

Treatments for breast cancer include surgical resection, chemotherapy, radiotherapy, endocrine therapy and targeted therapy. The specific methods are as follows: 1. Surgical treatment: Consider whether the tumor is completely removed according to the pathological stage, pathological type and molecular classification; 2. Chemotherapy: preoperative chemotherapy is called new adjuvant chemotherapy, postoperative chemotherapy is called adjuvant chemotherapy, and advanced patients are called palliative chemotherapy; 3. Targeted therapy: Gene immunohistochemistry method to detect more than 3 HER2s, or FISH method to detect HER2 expansion positive; 4. Radiotherapy: Use high-energy X-ray local breast radiation and lymphatic drainage area; 5. Endocrine therapy commonly uses tamoxifen and letrozole.
