The malignant cancer is a type of cancer that has the potential to spread across various regions in the body. This type of cancer is potentially more harmful to the body as it can invade across various tissues in the body. Your onclologist decides upon the best treatment for you after assessing your condition. Surgical reduction of cancerous tumour is a favourable method because it reduces the load on chemotherapy and other radiation therapies, as most of the infected tissue has already been removed. Surgical reduction helps in improving the effectiveness of other techniques used for eliminating the cancerous cells from the body.
