Overview
An elevated concentration of serum alkaline phosphatase is diagnostic of bone metastasis of breast cancer.
Blood Chemistry
Blood chemistry tests measure certain chemicals in the blood. They show how well certain organs are functioning and can also be used to detect abnormalities. They are used to stage breast cancer. [1]
- Urea (blood urea nitrogen or BUN) and creatinine may be measured to check kidney function. Kidney function is checked before chemotherapy is given and may be rechecked during or after treatment.
- Alanine aminotransferase (ALT), aspartate transaminase (AST) and alkaline phosphatase may be measured to check liver function.
- Increased levels could indicate that cancer has spread to the liver.
- Alkaline phosphatase can also be used to check for cancer in the bone.
- Increased levels could indicate that cancer has spread to the bone.
BRCA1/BRCA 2 Gene Testing
Genetic markers, if present, suggest an 80% likelihood of breast cancer occurrence.
HER2 Status Testing
- ERBB2 is a gene that has changed (mutated) so it helps a tumour grow oncogene. It is more commonly known as HER2 (or HER2/neu). HER2 stands for human epidermal growth factor receptor 2.[1]
- HER2 status testing is done to find out the amount of HER2 produced by a breast tumor.
