            manage to win over some antibodies by a method undiscovered to date.
                 As we have mentioned, antibodies are a type of protein that stops the
            activities of enemy cells. However, for some unknown reason, cancer cells
            are adversely affected by the antibodies. Instead of stopping, their activities
            increase, resulting in the rapid and forceful spreading of the tumour.
                 Antibodies, which bind themselves on to the surface of the cancer

            cell, "collaborate" with the cancer cell in a sense. Other antibodies do not
            touch a cancer cell having an antibody attached to it. Hence, the cancer
            cell is perfectly camouflaged.
                 Collaboration between antibodies and cancer cells can reach even
            broader dimensions. There are also occasions where cancer cells combine
            with antibodies to form "pseudo supressor T cells". These pseudo sup-
            pressor T cells misinform antibodies by relaying the message that there is
            "no danger". More sinister situations also develop whereby the cancer
            cells develop into "Pseudo Helper T cells" instead of the pseudo suppres-

            sor T cells. In such situations, the message is delivered to a bigger num-
            ber of antibodies. There can be no more convenient environment possible
            for the development of cancer cells.
                 Additionally, cancer cells may sometimes spread "trap antigens" in
            order to protect themselves from a possible attack by the defence system.
            These tumours spread out such large amounts of antigens from their sur-
            face that the blood stream is inundated with them. These antigens, howe-

            ver, are fake and cause no harm to the human body. However, the anti-
            bodies are not aware of this and they respond without delay by instigat-
            ing a war against them.
                 During this chaos, the real and dangerous cancer cells continue to
            function, going undisturbed and undiscovered by the enemy.
