癌细胞是向恶性发展的细胞,它四处扩散,破坏人体的健康组织,最后导致肿瘤,致人于死命。这种恶性裂变的细胞,如果发现得早,可以采取手术,加以切除。但在手术之后,采用的烈性药物或放射性治疗,时常产生恶劣的副作用。还有许多癌细胞是无法动手术切除的,唯一可行的疗法是是采用毒性药品或放射性治疗。这两种办法在杀死癌细胞的同时,也杀死了人体内大量的正常细胞,如病人在接受治疗后常出现毛发脱落,感到恶心或呕吐和昏睡无力等现象。有的病人在接受上述办法治疗时,免疫系统受到重大破坏,从而易患传染病,以至加速其死亡。
Cancer cells are malignant cells, which spread around, destroy the body’s healthy tissue, and finally lead to cancer, causing people to death. If such malignant fission cells are found early, they can be surgically removed and resected. However, after surgery, the use of potent drugs or radiotherapy, often have adverse side effects. There are many cancerous cells that are unresectable and the only viable treatment is the use of toxic drugs or radiotherapy. Both of these two methods kill the cancer cells and kill a large number of normal cells in the human body. For example, patients often experience hair loss, nausea, vomiting and lethargy after receiving treatment. In the course of treatment by some of these patients, the immune system is severely damaged, leading to epidemics and even death.
