癌症诊治过程中,经常遇到这样的情况:不幸接连降临同一个家庭,丈夫刚刚得了肠癌,妻子又被诊断出乳腺癌,连子女也难逃癌症威胁。虽然不排除家族性遗传因素,但不可忽视的是,他们共同生活的家庭环境促成了这种“巧合”。家庭环境不只局限于家中的卫生情况, In the course of cancer diagnosis and treatment, we often encounter such a situation: unfortunately one family has come one after another. Her husband has just got cancer, her wife has been diagnosed with breast cancer, and even her children cannot escape the cancer threat. Although it does not rule out familial genetic factors, it cannot be overlooked that the family environment in which they live together contributed to this “coincidence.” The family environment is not limited to the health conditions at home.
