There is no single success rate for tumour surgery; there are tumour types. Many common skin cancers, including most mast cell tumours and soft tissue sarcomas, are cured by complete first excision. Outcomes worsen with high grades, incomplete margins and late presentation, which is why testing early and cutting properly the first time carry most of the prognosis.
For skin and subcutaneous lumps, surgical risk is low: anaesthesia in assessed patients, wound complications, and the occasional drain are the realistic list. Internal mass surgery carries real bleeding and anaesthetic risks and belongs in hospitals set up for it, with blood on standby for splenic work. If a quote for an internal mass seems light on hospital care, that is worth querying rather than celebrating.
The cytology, the margins plan and the quote reviewed independently. From $250.
Sometimes margins are a planning miss; often they are anatomy, there was simply nothing spare to take on a lower leg. The report and the pre surgery records tell the story, and an independent review can distinguish bad luck from bad planning fairly quickly.
Veterinary chemotherapy is dosed for quality of life, not maximum tolerance, and most animals sail through it far better than humans fear. It is offered where it genuinely shifts outcomes; declining it is also a legitimate choice. Neither path is cruelty.
