Reasons why girls get breast cancer

The main causes of breast cancer are as follows: 1. Internal factors: abnormal female hormone levels and genetic factors, such as excessive estrogen or gene mutations in the family, can induce breast cancer. 2. External factors: physiological characteristics of being unmarried, childless, and not breastfeeding, obesity, long-term lack of exercise, excessive estrogen secretion, and unhealthy eating habits can also lead to an increase in the incidence of breast cancer. Frequent exposure to ionizing radiation and chemicals in work and life can also cause breast cancer.

What are the symptoms of triple-negative breast cancer?

Triple-negative breast cancer refers to breast cancer that is negative for hormone receptors, HER2 receptors, and progesterone receptors, and generally has a poor prognosis. Typical symptoms include painless breast masses, and physical examinations reveal that the surface of the mass is not smooth, the boundaries are unclear, and the mobility is poor. In the early stages of triple-negative breast cancer, orange peel-like changes in the breast skin, inverted nipples with local dimple signs, and nipple discharge, which is usually bloody. Axillary lymph nodes may also enlarge. Triple-negative breast cancer should be treated surgically in a timely manner.

How is breast cancer detected?

Breast cancer examination mainly involves physical examination combined with breast ultrasound examination. First, the doctor will conduct a physical examination of the breast by visual inspection and palpation to observe whether there are any changes in the appearance of the breast, as well as the location, size, texture, and mobility of the tumor. The doctor will also check whether the lymph nodes in the axilla and supraclavicular areas are enlarged, and make a preliminary judgment on the benign or malignant nature of the tumor. Then, a breast ultrasound examination will be performed, and the breast nodules will be graded using the BI-RADS classification. If it is above grade 4, the possibility of breast cancer is high, and a fine needle aspiration biopsy will be performed and sent to pathology to confirm whether it is breast cancer.
