My 80-yr-old mom's gum cancer, which has extended into a 3-4cm lump at her jaw (like a ping-pong ball), punctured from outside two days ago. No blood but some fluid keeps coming out. She is on the way back from rural China now but refuses to go back to the hospital that she's been consulting in the past 10 months. The problem is she remains suspicious of being misdiagnoised because she thought that the incisional biopsy performed on her last time had led to deterioration and added pain.

Two weeks ago she consulted another professor who is an expert in oral cancer. Although the consultation is only a confirmation of her situation, so advanced a stage that nothing can be done anymore (only 10% successful rate for surgery while chemo is impossible). She then went to rural China and took some medicinal plant for 10 days. Strangely, the pain has totally gone after 5 doses, and the size of tumor began to shrink. However, as I said it got punctured two days ago but she insists not going back for fear of more test and biopsy. Her wishful thinking is that when the fluid is drained her tumor will be healed but I am really worried.

Can anyone tell me what happens when a tumor punctures?
