这关键区别between invasion and metastasis is that入侵是指癌细胞指导和渗透到邻近的组织中,而转移是指癌细胞渗透到淋巴和血管中的能力,通过体内循环并侵入体内其他地方的正常组织。
癌症是细胞异常生长。自然,健康的细胞具有控制其分裂的机制。但是在癌症的发展过程中,细胞经历了无法控制的细胞分裂。Hence, a mass of cells is produced as a result of it. Also, there are more than 100 identified cancers.Chemotherapy, radiation or surgery are the treatment procedures for cancer. However, in order to control cancer, it is necessary to prevent spreading of cancer into healthy tissues and cells. Generally, cancer cells are capable of spreading throughout the body rapidly. These cells use two mechanisms; namely, invasion and metastasis to spread in the body. By invasion, cancer cell penetrates into neighbouring cells and tissues. By metastasis, cancer cells move and spread into another location of the body. Invasion and metastasis are the key features of cancer cells that distinguish them from other normal cells.

What is Invasion?
侵袭是癌细胞渗透到周围或邻近组织的机制。入侵标志着恶性肿瘤。当癌细胞通过入侵周围的组织而生长,分裂和迅速扩展时,相邻的组织会从其原始位置推开。良性肿瘤显示入侵,但没有显示转移。
However, malignant tumours show metastasis. Furthermore, the local invasion is the initial step of developing secondary tumours and leading to metastasis. Unless cancer cells invade tissue and enter into blood vessels or lymph, it cannot show metastasis.
什么是转移?
转移是一个致命的过程相关cers. It is the ability of cancer to move into a new location from the development site. In simple words, it is the capability of cancer cells to penetrate into blood vessels and lymphatic system and circulate throughout the body and invade a new tissue in order to grow and spread cancer. Once metastasis occurred, it is difficult to treat that cancer by removing the tumour from the original location. There is a chance of this particular cancer growing in new tissue. Therefore, these types of cancers are known as malignant cancers. Therefore, metastasis is the leading reason for the mortality of cancer patients as well as morbidity of cancers since it causes the development of a secondary tumour in new tissue.
Metastasis begins with invasion. Then these cells enter into the lymphatic system and vascular system by passing through the basement membranes and extracellular matrix. It is the process called intravasation. Once they penetrate into lymphatic and blood vessels, they circulate through the vascular system throughout the body (extravasation). At the end of the metastasis, these cells will attach at a new location and proliferate to produce a secondary tumour.
入侵和转移之间有什么相似之处?
- 侵袭和转移是癌细胞的关键特征。
- 它们是癌细胞在组织中传播癌症的机制。
- 在这两种机制中,癌细胞都渗透到引起肿瘤的新细胞中。
- 同样,肿瘤细胞与细胞外基质成分,上皮间质转变和血管生成是侵袭和转移的重要因素。
入侵和转移有什么区别?
侵袭和转移是两种机制,分别促进癌细胞扩散到邻近组织和远端器官中。在这里,入侵是指肿瘤扩展到周围组织的能力,而转移是指渗透到血管系统并进入远端器官并新生长的能力。因此,这是入侵和转移之间的关键区别。同样,为了发展继发性肿瘤,转移是必要的因素,而侵袭是转移的第一步。因此,这也是入侵和转移之间的差异。
此外,与入侵不同,转移是癌症死亡和发病率的最常见原因。以下关于入侵和转移之间差异的信息图显示两者之间的差异更多。
Summary – Invasion vs Metastasis
侵袭和转移是癌细胞的两个关键特征,可以将它们与其他细胞区分开。侵袭是癌细胞直接迁移和渗透到邻近组织中。另一方面,转移是将癌细胞扩散到原始位置以外的不同位置的组织和器官。因此,这是入侵和转移之间的关键区别。但是,两种机制都促进了癌细胞扩散到新组织中。但是,与入侵不同,转移会导致癌症患者的死亡率更高,因为从一个地方去除肿瘤将不足以治愈该疾病。在转移中,癌细胞通过血管系统循环并在新的位置建立,导致继发性肿瘤。因此,转移比入侵是一种严重的疾病。
