Cancer treatments become more effective when they are incorporated with heat. External heat therapy, otherwise known as hyperthermia, is recommended for superficial and recurring cancers. Research shows that this type of therapy is helpful in controlling the cancerous region and can help to increase chances of survival when used in conjunction to other treatments.
