Symptoms of unilateral breast cancer metastasis

summary

Breast cancer can be single or multiple. Breast cancer is a common cancer among female compatriots, while male compatriots occasionally suffer from it, but the risk is low. In recent years, from Julie to Yao Beina, there are many reports of stars suffering from breast cancer, which makes breast cancer gradually known and familiar. However, the public is not very aware of breast cancer metastasis. Do you know that the terrible thing about breast cancer is not breast cancer itself, but breast cancer metastasis. Symptoms of unilateral breast cancer metastasis? Let's talk about it

Symptoms of unilateral breast cancer metastasis

1. The rate of axillary lymph node metastasis in breast cancer patients is very high, which is the most common and early metastasis site, accounting for about 60% of the patients. The cancer cells infiltrate into the axillary lymph nodes along the lateral edge of pectoralis major. Axillary lymph node metastasis is related to the size of primary tumor. The larger the tumor volume is, the later the disease stage is, the higher the axillary lymph node metastasis is and the more the number of metastasis is. Clinically, even if the axillary lymph nodes are not palpable, postoperative lymph node metastasis is often found.

2. The most bone metastases were the thoracic, lumbar and pelvic bones, followed by the ribs and femurs; Most of them were osteolytic and a few were osteogenic; Pathological fracture may occur in long bone metastasis, paraplegia may be caused by spinal cord compression in spinal metastasis, and progressive pain may occur in clinic.

Hematogenous metastasis: breast cancer cells can directly invade blood vessels and cause distant metastasis. The vein of breast deep tissue, chest muscle and chest wall flowing into axillary vein, subclavian vein and innominate vein is an important way of lung metastasis. The incidence of distant metastasis of breast cancer is related to the size of primary tumor, the number of lymph node metastasis and pathological grade. The most common distant metastasis of breast cancer is lung, followed by bone, liver, soft tissue, brain and adrenal gland.

matters needing attention

Breast cancer is a very high incidence rate. Therefore, we should pay great attention to women's habit of developing good habits. Women who exercise regularly are 30% less likely to develop breast cancer than women who do not exercise. More exercise is not only good for health, but also can prevent the occurrence of breast cancer.
