Where in the body does breast cancer tend to spread?
Breast cancer starts in the breast, and the first place it goes to is the axilla or the armpit. That's where lymph nodes drain the breast. The cancer goes to the armpit first, and once it hits the lymph nodes there's a greater risk of the cancer spreading to the rest of the body. The cancer can go to the lungs, to the liver, to the bones, to the brain, the cancer can go pretty much anywhere in the body. It's really important to catch the cancer early when it's just in the breast. Once it has spread to the armpit and involves the lymph nodes there, it can still be cured. There's a greater risk of relapse but if it's only in the lymph nodes and the breast, it can still be cured. Once cancer spreads beyond the armpit and it's found in the lungs, the liver, the bones, the brain or another organ, at that point as a rule the cancer cannot be cured. That's why it is so important to catch the breast cancer early, when it's curable. It's always treatable, even if it has spread to other organs, but at that point the cancer is just not curable.
