The normal cells in the human body when starts growing or multiplying in uncontrollable fashion then it is called cancer 1. Over the time research has shown that a sudden genetic defect can cause cancer 2,3. It is also possible to have these genetic abnormalities through inheritance. However, researchers have also identified many different factors including chemicals or microorganisms can be a possible cause of cancer development 3,4.
It has become a daunting task for many scientists to find out what is the role of our immune system in cancer development. Why our immune system cannot prevent cancer cells to grow? What are the odds of a healthy person getting cancer? Ideally, the human immune system should repair and/or prevent any kind of damage to human cells that are affecting the normal body function. However, in spite of a good immunity we do get different diseases including cancer and this has been an ongoing challenge how to improve our immune system to prevent cancer 5.
Long history as major disease
Cancer has a long history of being one of the major diseases of human civilization. Therefore, there are many traditional preventive and treatment methods have been proposed other than the modern medicine 6-8.
It has also been observed that many bacteria and viruses are also associated with different cancer development in human 4,9,10.
The real question is if we can prevent these bacteria, virus or other environmental factors and also develop our immune system such way so that it can prevent any internal damage and combat disease like cancer? Scientists has approached this issue in many different ways.
Traditional Chinese medicine
For an example, in traditional Chinese medicine, there are several reported compounds that help in preventing cancers 11. Following research suggested that there are many pharmaceutical agents isolated from medicinal leech, earthworm, and Chinese Scorpion, and from herbal medicines derived from species such as Cordyceps militaris, Ganoderma, Momordica cochinchinensis, Viscum album, Poria cocos, Senna obtusifolia, Panax notoginseng, Smilax glabra, Ginkgo biloba, Dioscorea batatas, and Trichosanthes kirilowii compound has some anti cancer effect against many different cancers 12,13 .
Likewise, there are many natural products that have an anti-cancer property which might help to prevent the cancer cells to grow and proliferate 14,15. However, those compounds are not very well studied regarding their exact property, therapeutic dose, availability based on geographical area etc.
Scientists strongly believe that the human immune system can prevent cancer cells to grow
Irrespective of the conventional treatment method of cancers, scientists strongly believe that if the human immune system can prevent cancer cells to grow or even eliminate them to come back. Over the years many researchers have tried to boost the human system to prevent cancers.
This is also called Immunotherapy 16. In this treatment, the human immune system is used to prevent or treat cancer. This works exactly way human immune system fight against any bacteria or other pathogens. In this case, researcher use different human immune cells or cell product like types of white blood cell (T cells), antibody, cytokines etc to provide some extra help the patient’s immune system to attack cancer cells.
Prevention as a treatment strategy
Like vaccination, this is a similar kind of treatment strategy where patient’s immune systems are activated to kill cancerous cells and also prevent them from coming back 17. Because of its unique approach, it has become increasingly popular in many types of adult and childhood cancers 17-19. The reason being the activated immune cells can only find the cancer cells from their hiding places in the body to kill them which is difficult to chemotherapy or radiation like treatment.
This treatment can be given orally, through injection or topical based on the type of cancer and it can be done in normal clinical setup without any specific need 16,20-22. However, this treatment has some side effect which includes flue like symptoms, pain, swelling, rash, redness, itchiness etc.
The success of this treatment is highly variable from patient to patient depends on their immune response to this treatment 23. Therefore, this treatment has not been proposed for all types of cancer. Most of the patients get this kind of treatment based on doctor’s recommendation depending on their immune condition 24. To know more about this treatment please refer to our website Disorderfree.org where more articles and necessary direction for getting similar kind of treatment can be found.
