Metastatic Breast Cancer
Breast cancer starts to metastasize when it reaches Stage 4, this means that cancer cells from the breast have already spread to the different parts of the body such as in the bones, liver, lungs, and even the brain. The spread of cancer cells from the breast can happen when it invades the nearby healthy cells, and then after, the overtaken healthy cells will replicate abnormal cells. On the other hand, the fastest means of metastasizing is when cancer cells are able to be carried in the bloodstream as well as that of the lymph system. Through this, these cancer cells are easily circulated through the different parts of the body.
Metastasis of the breast cancer cells has different presenting symptoms, which largely depends on where the cancer cells are able to finally lodge. For instance, when they have metastasized to the bones, it will start to have symptoms like swelling on the site, severe and progressing pain, and bones are easily fractured. On the other hand, when it reaches the brain, it can cause seizures, vomiting, behavioral changes, and vision disturbances. For those lodged in the lungs, symptoms often include abnormal chest x-ray, chest pain, coughing, and difficulty breathing. On the other hand, metastasis on the liver can have symptoms like jaundice, abdominal pain, high liver enzymes, and rash on the skin.
