Once all this has been determined then a treatment plan can be formulated in conjunction with the patient. This will take into account things like the patients age and performance status - for example a frail, elderly man with prostate cancer may not be considered fit enough for surgery so might be offered hormone therapy instead. OTOH, a younger healthier man in his 60s might be offered a choice between surgery and radiotherapy - both offer similar cure rates but have different side effects.
Treatment options include: Surgery, chemotherapy, radiotherapy, hormone therapy and targeted therapy. A patient might have one, or more than one, depending on their diagnosis and personal situation, there is no "one size fits all" approach.
