The greatness of a woman lies in the fact that she nurtures a people. In this sense, women have a greater devotion than men. However, pregnancy is after all a special physiological activity that requires a strong energy metabolism and blood regeneration system of the organism as well as a strong compensatory function of the heart, lungs, liver and other organs to support the conception of a strong new life. A mother with leukemia is in a state of continuous metabolic depletion, and with the toxic effects of chemotherapy drugs on the heart, liver, kidneys, stomach and intestines, it is difficult for her organism to take on the burden of conception. Even if the pregnancy is narrowly passed, the leukemia still poses a threat to the life of mother and child during delivery because of its propensity for infection and bleeding. For the fetus, the embryo is a newly sprouted seedling that cannot grow healthily without fertile “soil” and sunlight. In the mother’s body, the embryo has to compete with the leukemia cells for nutrients, and is attacked by the leukemia cells and chemotherapy drugs. Their growth is very slow and some of them are deformed, suffer from congenital leukemia or die. Therefore, in order to fight for the therapeutic remission of leukemia patients, for the health of the family and the hope of the nation, it is better for leukemia patients not to choose pregnancy.
