Quite a few elements can impact the lifespan and general performance of your respective Tesla’s battery, likely influencing the guarantee coverage:
Tesla warranties do transfer to new owners, but provided that the transaction is finished fully with the company. The first or previous operator have to provide the car or truck to Tesla and The brand new operator have to invest in the vehicle from Tesla for guarantee coverage to transfer above.
臨床實驗是抗癌研究長期研發實驗的最後一個階段。找尋新的治療方法通常是在實驗室裡開始進行，研究員不斷測試和實驗新的對抗癌症的想法。如果找出有潛力的治療方式，首先要先進行動物實驗，觀察此新療法實際施行在生物體上是否確實有效，或是帶有未知副作用等問題。在實驗室與動物實驗都很有效並不能代表同樣的方法在人體身上能夠成功，因此要等臨床實驗結束，才能確定新的治療方法是安全有效的。
癌症篩檢的爭議在於檢驗是否的確能夠延長生命，由於癌症的治療方法多半具有侵入性及對身體造成很大負擔，因為早期發現而進行治療反而不一定比完全不治療好。例如，在進行前列腺癌篩檢時，攝護腺抗原血液檢驗可偵測到極微小的腫瘤，但是或許終其一生，這樣的腫瘤並不會成為危及生命的問題。只是一旦經篩檢發現，一般都會進行進一步的檢驗及診療。因此就有可能發生過度診斷（英语：overdiagnosis）的問題，而將病患放入不必要的併發症的風險中，如手術或放射治療的副作用與感染。用於確定診斷前列腺癌所做的前列腺組織切片可能引起的副作用，包括出血和感染。前列腺癌的治療則可能導致尿失禁、勃起功能障礙。同樣地，對於乳癌的篩檢上，近來也有批評認為在一些國家所進行的乳房篩檢計畫所引起問題遠超過所解決的。因為在一般婦女身上做篩檢，產生許多因為陽性或假陽性結果而需要做更精確檢驗的婦女，造成醫療資源的大量浪費，也帶給假陽性者的沉重心理負擔。而這樣大規模的檢驗，最後往往只是找出幾個早期乳癌患者，所耗費的社會成本是值得討論的。

癌症的治療無論是化療、手術或放療都是對身體有極大負擔，並且在發生惡性轉移後，無論是何種方式都是很難徹底治癒。所以在癌症的治療仍然是人類面對的極大考驗。在目前對於年老的癌症患者，或許找出能維持生活品質並讓其能平靜走向生命旅程的終點的治療方式，會是比積極消除癌細胞而使用副作用極大的治療方式要來的實際且重要。
Even house owners of Tesla autos which can be qualified for your extended assistance arrangement may want to take into account independent guarantee firms. That’s mainly because these providers present many crucial advantages above company extended warranties like Tesla’s choice, like:

理論上，若是以手術完全移除腫瘤細胞，癌症是可以被治癒的。但並非總是如此簡單，外科手術通常無法切除已經轉移到其他部位的癌細胞。使用外科手術治療癌症的例子包括以乳房切除术治療乳癌或是進行前列腺切除術（英语：prostatectomy）治療前列腺癌。手術的目的在於移除腫瘤細胞或是整個器官，雖然將主要的腫瘤經外科手術切除，但仍有些潛伏在腫瘤所生長的器官週遭的單一腫瘤細胞是無法被察覺的。隨著時間過去，又會重新生長成一個新的腫瘤，稱為癌症復發。為此，手術切除下的腫瘤需要經病理學家的檢視，以確定切下的腫瘤週遭都是正常組織，減少腫瘤切除不完全的機會。
