童年期的癌症影响与成年人完全不同。它们的生长趋势较为迅速,而且可以生在不同的器官系统。儿童很少患肺癌、乳房癌,或结肠癌。这些癌症在成年人中却是最常见的。在一切可能性中,儿童患癌的原因十之八九也与成年人完全不同。由于接触致癌化学物的年份有限,儿童就没有足够长的生活年限使癌发展。的确,童年期的癌症更可能与某些胎内影响有关,例如受某些致癌激素影响,或是免疫系统的缺陷。此外,也许与某些至今尚未弄清楚的传染性媒质以及某些完全不明的原因有关。治疗童年期癌症的可怕的并发症,也是完全异常的。治疗童年期癌症的专家们经常致力于探索改进治疗方法。他们不仅要治愈更多的癌症患者,而且更要减少癌症带来的严重的后遗症。有时候,用于治疗儿童期癌症的强效疗法,在癌症成功地根除几年之后,却引起了不少问题。
Childhood cancer affects completely differently from adults. Their growth tends to be more rapid and they can be born in different organ systems. Children rarely suffer from lung cancer, breast cancer, or colon cancer. These cancers are the most common among adults. Among all possibilities, the cause of cancer in children is totally different from that of adults. Due to the limited years of exposure to carcinogenic chemicals, children do not have enough life spans to develop cancer. Indeed, cancer in childhood is more likely to be associated with certain fetal effects, such as the effects of certain carcinogenic hormones or defects in the immune system. In addition, it may be related to some infectious media that have not yet been clarified and some completely unknown reasons. The terrible complications of treating childhood cancer are also completely abnormal. Experts who treat childhood cancers often work to explore improved treatments. They not only need to cure more cancer patients, but also reduce the serious sequelae that cancer brings. In some cases, the powerful treatment for childhood cancer has caused many problems after the cancer was successfully eradicated several years later.
