Where Does Breast Cancer Spread?

Breast cancer can spread to different parts of the body, including:

1. Lymph Nodes: Breast cancer can spread to the lymph nodes under the arm, above the collarbone, and around the breast. Lymph nodes are part of the body's immune system and can act as a pathway for cancer cells to travel.

2. Bones: Breast cancer commonly spreads to the bones, especially the spine, ribs, pelvis, and long bones like the femur and humerus. Bone metastases can cause pain, weakness, and fractures.

3. Lungs: Breast cancer can spread to the lungs through the bloodstream. Lung metastases can cause symptoms like shortness of breath, chest pain, and coughing.

4. Liver: Breast cancer can spread to the liver, affecting its function and causing symptoms such as jaundice (yellowing of the skin and eyes), fatigue, and abdominal pain.

5. Brain: Breast cancer can rarely spread to the brain, leading to symptoms like headaches, seizures, vision changes, and neurological deficits.

6. Other Organs: In some cases, breast cancer can spread to other organs, including the skin, ovaries, adrenal glands, and even the opposite breast.

The spread of breast cancer is referred to as metastasis. When breast cancer cells metastasize, they travel through the lymphatic system or bloodstream to reach distant sites in the body. Metastasis is a late stage of breast cancer and is associated with a more advanced and aggressive disease.

It's important for individuals with breast cancer to receive regular follow-up care and monitoring to detect any signs of metastasis or recurrence. Treatment for metastatic breast cancer may involve a combination of therapies, including chemotherapy, radiation therapy, targeted therapy, hormone therapy, and surgery, depending on the specific stage and characteristics of the cancer.
