Don't give up if you are diagnosed with metastatic cancer; there are options available that can help you manage your condition. Treatments like immunotherapy and radiotherapy can be effective, and advanced techniques such as SABR (Stereotactic Ablative Radiotherapy) might also be recommended. It's important to explore these options to potentially avoid the need for a stoma bag, especially if you're dealing with bowel cancer. Stay hopeful and informed about your treatment possibilities.
