癌細胞是基因突變的細胞。正常人體都有基因突變的細胞，之所以沒有變成癌症，是因為有正常的免疫係統，它監控，殺死癌細胞。所以在正常的免疫係統監控下，癌細胞是不可能演變成癌症的，這是醫學上公認的事實。
從這種意義上來說，癌症隻是機體免疫係統功能低下的表現形式，表現在肝是肝癌，表現在肺是肺癌，在胃是胃癌。真正的病是免疫係統 (Immune system) 出了毛病，需要治療的不是癌症本身，而是機體的免疫狀態，隻有機體的免疫狀態被調整到正常水平，癌症才能康複，否則，任何隻針對癌症本身的治療都隻能是治標而不治本。
現實生活中，許多癌症尤其晚期癌症被治愈的例子，反複證明了這一點。他們共同的特點是有樂觀向上的心態、戰勝癌症的信心和勇氣，以及合理的睡眠飲食調整，這些和諧的因素讓機體整體機能回複到正常狀態，癌細胞被體內恢複正常的免疫係統殺滅。
身體的免疫力不光取決於遺傳基因，環境的影響也很大，如飲食、睡眠、運動、壓力等。其中飲食具有決定性的影響力，因為有些食物的成分能夠協助刺激免疫係統，增強免疫能力。如果缺乏這些重要營養素成分，會嚴重影響身體的免疫係統機能。
提高抗癌免疫力的幾種食物
1、靈芝山藥增強免疫又抗癌
靈芝 靈芝味甘苦、性平，歸心、肺、肝、脾經；http://www.cnkang.com/zyzy/zhuanti/lingzhi/ 具有養心安神，補肺益氣，滋肝健脾的功效；可增強人體的免疫力，這是因為靈芝含有抗癌效能的多糖體，此外，還含有豐富的鍺元素。鍺能加速身體的新陳代謝，延緩細胞的衰老，能通過誘導renti產生幹擾素而發揮其抗癌作用。

山藥裏含有人體所需要的維生素和礦物質。因此，吃山藥是大補。增強營養的同時，還可以提高免疫力。如果與羊肉同吃，效果會更好。
2、香菇：香菇具有調節人體新陳代謝、降低血壓、降低膽固醇、糖尿病及癌症、治療貧血等功效。近年來，美國科學家發現香菇中含有一種“β-葡萄糖苷酶”，這種物質有明顯的加強機體抗癌的作用，所含香菇多糖或香菇水解提取物對癌有高效抑製作用，抑癌率達50%，因此，人們把香菇稱為“抗癌新兵”。
3， 胡蘿卜：胡蘿卜中含有豐富的胡蘿卜素，其中的β-胡蘿卜素有明顯的提高機體免疫力，抑製腫瘤的發生和發展的作用，並且還可降低腫瘤患者接受放化療時的毒副反應;
4、絲瓜：其種子及果皮可抑製癌細胞，能增強肺、胃及肝髒功能，汗液可排除人體內的毒素，果髓有助治療灼傷、燙傷及感染等。
5、黃豆：黃豆中富含優質蛋白質及多種營養素。能防止血液提供營養給癌細胞,防止癌症擴散，改善細胞的免疫力。
6，仙人掌：仙人掌中含多種植物營養素，有抗突變作用，可抑製腫瘤生長，並在控製癌細胞的同時對白細胞的數量無影響，對於輔助放、化療有所幫助。仙人掌中所含有的多糖、角蒂仙、包壁蓮和玉芙蓉等物質都有助於抗癌防癌。
Continue from yesterday, and talking about Vit B12, remember a young guy in his 30th came to clinic with unstoppable bleeding per rectum. He's so slim and pale, and blood work show pancytopenia- the count for red blood cells, white blood cells and platelets are all low, and VitB12 level is undetectable in his serum. He has been on strict veg diet for over ten years. B12 can rarely be acquired from the plant. Vit B12 is needed for DNA formation, No DNA, No cells. all the blood cells, esp white blood cells , the main fighters of the immune system, cannot generate and function properly with B12 deficiency. Now thinking of Mr. steve Job, also a vegatarian, his tumor spread quickly within 9 months with this celebrity favorite veg diet. Overall, ur choice of ur diet decide the strength of ur immune system, and the ultimately ur health.
如何去增強免疫力?
天人一體，法於陰陽，和於術數，飲食有節，起居有常，不妄勞作，春生夏長, 秋收冬藏. 陰平陽秘，精神乃治. For stage 4 cancer patient, usu. immune function is in bad shape. I recommend 好的中醫中藥調理以扶正immune function。
會不會也去開刀，化療，放療？
I'll work aggressively with my doctor to find the best regiman for my own, depending on the type of tumor, patological type and staging. Some tumor can be cured by resection, why not surgery?
化療，放療---Routinely, people think chemo is very cytotoxic. That is Traditional chemo agents, that is to say they act by killing cells that divide rapidly. This results in the most common side-effects of chemotherapy: myelosuppression (decreased production of blood cells, hence also immunosuppression), mucositis (inflammation of the lining of the digestive tract), and alopecia (hair loss).
However, Some newer anticancer drugs (for example, various monoclonal antibodies) are not indiscriminately cytotoxic, but rather target proteins that are abnormally expressed in cancer cells. Such treatments are often referred to as targeted therapy (as distinct from traditional chemotherapy). Recently, my little patient Alex has extreme bone pain and cannot even stand to bare his own weight. PET scan show right leg lytic bone lesion with brain and multiple bones mets. The pain of cancer invading bone is unbearable. Everytime, when we check him, he always squeeze some smiles to cover his pain. His cancer is positive for CD30 and ALK-1 protein expression. Fortunetely, there are 2 separate clinical trials of monoclonal antibody to treat cancer with these 2 proteins expression. With one week's anti-CD30 and anti-ALK therapy, PET show clear of cancer and the little Alex can run happily in the floor now. However, not every cancer patent is so lucky to have tareted therapy reagents. One of my favorate attending got colon cancer with one positive lymph node. So far, only traditional chemo can be applied for her cancer type. She was on top of the every side effect of the chemo agents she used. Once she felt the side effect like symptoms, she will actively talk with her oncologist to stop or lower the dose. Make sure her body can tolerate the chemo during the entire cycle. She was cancer free with the surgery and chemo. 我崇尚名中醫陸維民大夫的腫瘤整體治療方案－－‘攻，破，行， 養'. 重在 ‘行， 養' 去扶正提升機體免疫功能。在身體能承受情況下，盡量去‘攻，破’ kill cancer cells, that is surgery, chemo and radiation therapy.
God bless u and ur loved ones,
Best,

Agree ‘症與病之間沒有絕對的界限’。就象‘寒極生熱，熱極生寒’。症與病可隨免疫功能的強弱而轉化。症重而病，病緩而症。 Mr. Steve Job was diagnosed of pancreatic neuroendocrine tumor in 2003 during a CT scan and other tests. Unlike pancreatic ductal carcinoma, with neuroendocrine tumor “if you catch it early, there is a real potential for cure,” says cancer surgeon Joseph Kim of City of Hope. Doctors urged him to have an operation to remove the tumor and he will be cured, but Mr. Jobs put it off and instead tried a vegan diet, juices, herbs, acupuncture and 靜坐禪修. Nine months later, the tumor had grown and spread to his entire liver, that is the example of 症重而病 . Only then did he agree to surgery, the liver transplant and wipple procedure extend his life to 2011, but still cannot save him from the wide spread tumor. The immune system's normal function need quite a lot high quality proteins and Vitamins, like B12. Vitamin B12 is naturally found in animal products, including fish, meat, poultry, eggs, milk, and milk products, generally not present in plant foods. strict veg diet cannot provide enough nutrients for the immune system to function normally. appropriate amount of High quality organic meat and diary products are recommended for the normal immune function. (本人飲食養生淺見，見仁見智）。
回複‘峰杏’：
Cancer cell derives from normal cells. They do look like normal cells, but there are still difference b/w them. The immune systerm can identify the difference and kill the cancer cells and ignore the normal cells. The human body’s first line of defense against cancer is the natural killer (NK) cell， second line is lymphocytes,esp. cytotoxic T cells. NK cells and T cells are white blood cells that actively scan the body for abnormal cells, destroying them before they can develop into actual cancers. Some cancer cells, however, evade destruction by engaging some specific receptor, such as the NK cell’s killer inhibitory receptor (KIR). By triggering this “master-off switch,” rogue cancer cells can evade destruction and form tumors. Therefore, there is a trade-off b/w ur immune systerm and cencer cells, which can outsmart the other. When we are young and the immune systerm is sharp, we are less likely to grow the cancer. U may dispute some kids have cancers. Those kids usu. had inborn immune error like DeGeorge Syn with no thymus ( T cell organ), no T cells to fight cancer cells.

U 2 sounds like one person, and i agree with ur points.
添加劑，色素，防腐劑 contain toxins, which are like 雙刃劍，can cause DNA replication and repair errors like mutation, also compromise our immune system. 事實上，免疫係統的功能本身是很強的，添加劑等毒素會致使免疫係統的功能逐漸下降。用食物增強immune function and avoid 添加劑，色素，防腐劑 相得益彰， 並無矛盾吧。

1，會如何樂觀
I understand it really really hard. The love and surpport from families are critical. The inspiring story from other cancer survivors and the knowledge on how to win this battle all can help.
Here is a psychotherapy trial link in Toronto for cancer Patients. Hope it canbe helpful to ur friends.

Too late, I'll type more TMW.
問好 Needtime, agree with ur comment. 謝謝光臨
Hi my old friend,
SO nice to see u. U really refine my point to a higher level, and I am quite innocent in spiritual part of life. Thx for the link, will read it when I can slow down.
Take care and best wishes to u & ur families.
保持免疫係統健康，不僅僅在外在因素，同時也關聯內在因素；比如人自身的情緒。
如果將內外結合，那麽素食加靜坐（打坐）應當是比較好的方法。
除了個別例外， 人們隨著年齡增加，肌體功能是越來越弱的。 現象是癌症患者隨著年齡增加，人數多起來！
至於年輕的患者，應該是基因問題了。現代社會，嬰兒死亡率很低，之前的時代難以存活的嬰兒也都得以成長成人，
這部分群體容易患各種疾病，癌症僅僅是其中之一。
更重要的是，要知道什麽不能吃。
列出經常吃的食物，好好查查它們的成份，看看含有多少添加劑，色素，防腐劑等等，
這些才是癌症的頭號原因
