激光辐射治疗是一种比较新的技术,利用激光——血卟啉(HPD)可以治疗癌症。激光照射前2～3天,将血卟啉静脉注射入人体中,它能有选择地聚集,潴留在恶性肿瘤组织内,然后用红色激光照射恶性肿瘤,恶性肿瘤组织内的血卟啉在红色激光的照射下活跃起来,变为具有毒素的药物,从而杀死恶性肿瘤细胞。这种方法对体表方面的黑色素瘤,皮肤及口腔鳞状上皮癌,乳腺癌治疗效果较好,尤其是对乳腺癌被切除的患者采说,激光辐射治疗最为有效。激光是通过长4.8米的光导纤维传给治疗部位的。激光从光导纤维末端发出,只要
Laser radiation therapy is a relatively new technology that can treat cancer with laser-hematoporphyrin (HPD). 2 to 3 days before laser irradiation, hematoporphyrin intravenously injected into the human body, it can selectively gather, retention in the malignant tumor tissue, and then use red laser irradiation of malignant tumors, hematoporphyrin in the malignant tumor tissue in red Lasers activate to become toxins that kills malignant cells. This method of body surface melanoma, skin and oral squamous cell carcinoma, breast cancer treatment is better, especially for patients with breast cancer was removed, said laser radiation therapy is the most effective. The laser is delivered to the treatment site through a 4.8-meter long optical fiber. The laser is emitted from the end of the optical fiber as long as
