summary

Breast cancer is one of the most common malignant tumors in women, and patients have different symptoms in different periods. Among them, the symptoms of cancer cell metastasis and diffusion bring great harm to patients, which needs our attention. So, what are the symptoms of advanced breast cancer after metastasis? Here is a detailed introduction.

Cervical metastasis of breast cancer?

Axillary lymph node metastasis rate of breast cancer patients is very high, which is the most common and early metastasis site, accounting for about 60% of the patients. Cancer cells infiltrate into 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.

The metastasis rate of parasternal lymph nodes is about 30% ~ 50%. The cancer cells infiltrate into the parasternal lymph nodes and then reach the supraclavicular lymph nodes. The tumor thrombus can also flow back to cause pleural or spinal 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

Most of the pulmonary metastases were nodules of different sizes in the lung, occasionally a single nodule. A few cases showed carcinomatous lymphangitis with obvious cough, shortness of breath and cyanosis.
