What happens if you have a malignant tumor, do you have to get it removed?

A must: The philosophy for malignant tumors is that if you leave them alone they 'Grow on You'. The procedure to be employed is not radical resection but adequate removal. If adequate is not performed the procedure is inadequate. Certain lesions if very large however may need neoadjuvant chemotherapy before removing. The approach also depends on location, nature of the lesion and size
