我也想请问那些质疑癌症化疗的人几个问题

实在是看不下去了有些人在恶意或者善意的误导病人。

请那些打压化疗功效的人先回答我几个问题： 请问你得过癌症吗？你家里有人得癌症吗？如果你或你的至亲之人得了癌症，你敢不敢放弃传统治疗（手术，放化疗）用自己的性命来赌一把那些自然疗法，包括气功等等的功效？

首先，我肯定自然疗法的积极的地方，特别是蔬果汁作为一种辅助增进身体抵抗力的手段。但是，有没有任何临床上癌症治愈的例子是完全靠着喝蔬果汁成功的呢？如果有，比例是多少？我说的比例意思是： 10000个（乳腺，卵巢，肺，肝等等）癌患者，靠着蔬果汁，5年的存活率是x%。请不要用某个人张三靠着喝了蔬果汁肺癌痊愈的这样的例子，没有代表性。我需要的是临床大组分析数据。因为对于癌症这种自身免疫调节出问题的病，有些人可能根本不用做什么事，自己DNA就可以修复自愈，但是拿这个说事就显得没有意义，对吧？

然后，我来说一组数据，我在加拿大只能用加拿大数据（懒得翻译，各位自己看）： 请注意15年来加拿大癌症存活率的提升。而且文章提到了这些提升的原因，我用下滑线表示了出来。

the long-term prognosis has generally improved for most types of cancer since the 1990s — sometimes markedly, according to new data from the Canadian Cancer Registry.

The overall five-year survival rate of Canadians diagnosed with cancer in the period from 2004 to 2006 is estimated to be 62 per cent of that of an identical group without cancer.

That's up slightly from 60 per cent for cancers diagnosed in the 1998-2000 period. In the 1994-1996 period, the ratio was 57 per cent.

"We are heartened to see that ... the overall five-year survival rate is 62 per cent and that's holding steady," said Gillian Bromfield, senior manager of cancer control policy with the Canadian Cancer Society.

"We want to see that go up. Sixty-two per cent is still in my mind, too low."

The 10-year survival rate is almost as high as the five-year rate — it's estimated at 58 per cent for cancers diagnosed in the 2004-2006 period.

"A diagnosis of cancer does not usually mean that death is imminent," the study notes.

The five-year relative survival ratio compares the observed survival of a group of people with cancer to the expected survival of other individuals assumed to be cancer-free.

For some cancers, the survival ratio has gone up appreciably. Liver cancer, for instance, saw its five-year survival rate almost double from nine per cent in 1992-1994 to 17 per cent. Leukemia's five-year survival ratio went from 44 per cent to 54 per cent and non-Hodgkin's lymphoma rose from 51 per cent to 63 per cent.

Reasons for improvement

For some cancers, long-term survival is very likely. The five-year survival rate for thyroid cancer is 98 per cent; prostate cancer's five-year rate is 96 per cent; and for testicular cancer, it's 95 per cent.

Breast cancer's five-year survival rate is now 88 per cent. It was 87 per cent in the 1998-2000 period.

"Big numbers like this usually don't lie," said Dr. Tom Hudson, president and scientific director of the Ontario Institute for Cancer Research in Toronto.

Hudson attributed the improved survival ratios to:

• Early detection of tumours that tend to be smaller and less aggressive.
• New treatments like Herceptin for 15 per cent of breast cancers.
• Greater availability of screening tests for colorectal and cervical cancers and melanoma.
• Safer forms of chemotherapy that have reduced complications.

我身边有癌症控制的很好活了很长时间的，但是无一例外的在诊断后都经过了痛苦难熬的放化疗。然后是多年来对自己不健康生活方式的改变，比如以素食为主，肉食少量，坚持锻炼身体，保持积极乐观心情等等。

其他的我也不说了，有些人没得过癌症根本不理解癌症病人和家人的心情。我经历过癌症，我只能和大家说，一定还是听医生按照正统治疗方案走，其它的辅助自然疗法可以参考，可以选择性采纳，但是这些不能作为你的主治疗方案。
