補充和替代醫學
補充和替代醫學（CAM）是不屬於標準醫療服務的醫療產品和慣例的術語。
- 標準醫療 是持有醫學博士學位（醫學博士學位）或醫學博士學位的衛生專業人員實踐的藥物。 （骨病醫生）學位。 其他保健專業人員（例如理療師，醫師助理，心理學家和註冊護士）也採用這種方法。 標準藥物也可以稱為生物醫學或同種療法，西方，主流，正統或常規醫學。 一些標準的醫療從業人員也是CAM的從業人員。
- 補充醫學 是沿著使用標準的醫學治療，但不被認為是標準的治療方法治療。一個例子是使用針灸來幫助減輕癌症治療的一些副作用。
- 替代藥物 是用來代替標準醫療的療法。 一個例子是使用特殊飲食來治療癌症，而不是由腫瘤科醫生處方的抗癌藥物。
- 中西醫結合 是將標準藥物與已證明是安全有效的CAM做法相結合的整體醫療護理方法。 他們對待患者的思想，身體和精神。
NCI為患者和醫護人員提供了許多版本的CAM治療的循證PDQ信息。
CAM方法安全嗎？
一些CAM療法經過了認真的評估，被發現是安全有效的。 但是，發現其他一些無效或可能有害的東西。 人們對許多CAM療法知之甚少，並且由於以下幾個原因，研究進展緩慢：
- 時間和資金問題
- 尋找機構和癌症研究人員進行研究的問題
- 監管問題
CAM療法需要使用與評估標準療法相同的漫長而仔細的研究過程進行評估。 通常已經通過包括對大量患者進行臨床試驗在內的激烈科學過程對標準癌症治療的安全性和有效性進行了研究。
自然並不意味著安全
CAM療法包括多種植物藥和營養產品，例如膳食補充劑，草藥補充劑和維生素。 許多「天然」產品被認為是安全的，因為它們存在於自然界或由自然界生產。 但是，並非在所有情況下都是如此。 此外，某些藥物可能會影響其他藥物在您體內的作用。 例如，某些人用來抑制抑鬱的草藥聖約翰草可能會導致某些抗癌藥物無法正常發揮作用。
本身，與其他物質或大劑量服用時，草藥補品可能有害。 例如，一些研究表明，卡瓦卡瓦（一種用於緩解壓力和焦慮的草藥）可能會引起肝臟損害。
Vitamins can also have unwanted effects in your body. For example, some studies show that high doses of vitamins, even vitamin C, may affect how chemotherapy and radiation work. Too much of any vitamin is not safe, even in a healthy person.
Tell your doctor if you're taking any dietary supplements, no matter how safe you think they are. This is very important. Even though there may be ads or claims that something has been used for years, they do not prove that it's safe or effective.
Supplements do not have to be approved by the federal government before being sold to the public. Also, a prescription is not needed to buy them. Therefore, it's up to consumers to decide what is best for them.
NCI and the National Center for Complementary and Integrative Health (NCCIH) are currently sponsoring or cosponsoring various clinical trials that test CAM treatments and therapies in people. Some study the effects of complementary approaches used in addition to conventional treatments, and some compare alternative therapies with conventional treatments.

What Should Patients Do When Using or Considering CAM Therapies?
Cancer patients who are using or considering using complementary or alternative therapy should talk with their doctor or nurse. Some therapies may interfere with standard treatment or even be harmful. It is also a good idea to learn whether the therapy has been proven to do what it claims to do.
To find a CAM practitioner, ask your doctor or nurse to suggest someone. Or ask if someone at your cancer center, such as a social worker or physical therapist can help you. Choosing a CAM practitioner should be done with as much care as choosing a primary care provider.
Patients, their families, and their health care providers can learn about CAM therapies and practitioners from the following government agencies:
- National Center for Complementary and Integrative Health
- NCI Office of Cancer Complementary and Alternative Medicine
- Office of Dietary Supplements
