Heating the cancer cells:  Using imaging tests like CT scans, MRI scans, and ultrasound as a guide, thin needles are inserted into the belly through small incisions, and an electric current is pushed through to burn and kill cancer cells.

Freezing cancer cells: The doctor locates the tumours using ultrasound images, then inserts a cryoprobe containing liquid nitrogen directly on the tumours, killing the cells due to the extreme cold.

Alcohol injections to the tumor: To force cancer cells to die, alcohol is injected into them through the skin or during surgery.

Chemotherapy: Chemotherapy is the process of administering powerful anti-cancer medications directly to the liver.
