Hi, thanks for using healthcare magic
I am sorry that your mother is unwell.
The term metastasis means spread of cancer from one part of the body to the other. The MRI
states that the areas were suspicious for cancer, meaning that it is not definite.
The tests that the doctors are doing are to determine if cancer is present and if so, where is the primary (the original area of the cancer).
This will influence treatment because different drugs are used depending on the type of the cancer present. Advances have been made that allow for better treatment and cure of cancer depending on its stage.
I hope helps and wish your mother well
