To make an operation is never a treatment. Tumours grow in the body for a reason. Try to understand which kind of poison your body is trying to get rid of in this way. Something else can take it away, like onion juice. So: every morning before you eat or drink anything else drink the juice of one onion. After that do not eat or drink anything for 1 hour. Within 40 days your tumour should be cleaned away, insha’Allah.
