A brief analysis of the common sites and pathways of breast cancer bone metastasis

Breast cancer bone metastasis refers to the metastasis of cancer cells to the ribs, sternum and other parts of the breast cancer patient, further endangering the patient's health. In view of this, the following will talk about the common locations and pathways of breast cancer bone metastasis .

1. Location of breast cancer bone metastasis

Breast cancer bone metastasis is also a common type of breast cancer. However, since bone destruction is not obvious in the early stages of breast cancer bone metastasis, it is not easy to detect it in time, whether by X-ray or CT bone scan. The rate of breast cancer bone metastasis found in autopsy is 2 times higher than that diagnosed clinically.

The pelvis, spine (most common in the lumbar vertebrae, followed by the thoracic vertebrae) and femur are the most common sites of breast cancer bone metastasis; ribs, skull, scapula, ribs, etc. are also common; while breast cancer bone metastasis to the distal hands, metatarsal bones, toe bones, elbows and knees is extremely rare.

2. The main pathways of breast cancer bone metastasis

Breast cancer bone metastasis is all blood-borne. In addition to blood-borne metastasis from the lungs into the systemic circulation, it can also metastasize into the vertebral venous system through the intercostal veins, directly invading the skull, spine, and pelvis, so blood-borne metastasis from the vertebral veins is an important way for breast cancer bone metastasis.

The above is an introduction to the common sites and pathways of breast cancer bone metastasis. I believe that everyone has some understanding of breast cancer bone metastasis.
