Is there a way to know if a tumour is cancerous or not by way of a scan?
How is the cancerous nature of a tumor detected?

Not 100 percent, which is usually by histopathology, but in many cases by USG and cross-sectional imaging methods like CT/MRI lesions, whether cancerous or not, can be made out.
Sometimes. However, biopsy is still recommended to determine the optimal treatment. Particularly, with new advanced genetic therapies.
MRI spectroscopy is 92% accurate. In the future, it will probably be approved to replace biopsy, which has the problem that the biopsy may spread the cancer cells.
Usually requires a biopsy. Rarely imaging characteristics are highly suggestive but best to confirm.
Images can suggest whether a mass is cancerous, but pathology is usually definitive.
Imaging studies can be helpful to show masses that may represent malignant cancers. Biopsy is often necessary to make an exact diagnosis.
