Symptoms tell them what tests to do MRI ,ultrasound, blood work ,kind of depends on the type of cancer
MRI's or X-rays are used to detect lumps, but they're not confirmed as cancers until a biopsy is done, which nowadays can be done without a surgery.
In order to detect cancer, the cells must be examined with a microscope. xrays, ultrasound can detect tumors, but only provide a clue as to whether they are cancerous. Blood tests can provide a clue and in some cases you can look at the cells. In some cancers, you might get cells in the urine. Sometimes you can get the cells with a swab. Mostly, it requires a biopsy, a surgical procedure.
