We’ve harnessed electricity, sequenced the human genome, and eradicated smallpox. But after billions of dollars in research, we haven’t found a solution for a disease that affects more than 14 million people and their families at any given time. Why is it so difficult to cure cancer? Kyuson Yun explains the challenges.

    Cancer is an extremely difficult disease, and the only hope we have to cure it is to understand it. If you'd like to get up to speed on where we are in this journey, the book we recommend at the end of this video is a great place to start. You can download a free audiobook at http://adbl.co/2gauxND. And for even more book recs from our team, visit http://bit.ly/2wKOs9c.

    Bosan aku dengan Cancer. Dari dahulu datang lagi. Menjauhkan diri daripada Keluarga & Agama buat sementara jelah cara nak pulih dari Cancer Buah Pinggang. Berapa banyak Chemotherapy pon macam tu jugak. Lebih baik mati muda dari dulu lagi bagus semak kepala aku dengan penyakit ni.

    a good way of treating cancer is by touching/holding the Quran for 5 minutes and reciting ayat al kursi and the quls

    this does it

    do it at 6:01 am morning and 20:01 pm night, you should do the touching/holding Quran part only once in the morning, don't need to do this one at night again

    do ayat al kursi and quls in the morning and at night (I got this from the hadiths of the prophet)

    you will be cured over time / I don't know if short or long

    do this every day

    Animal fats are like hormone producing factories that alter hormones. Combined with its ability to store environmental toxins. What could go wrong?

    Summary:
    1) Tested on lab grown cell lines- Cancer cells are much more complex when thriving in the body. This means while a new treatment was effective when tested on cancerous cells, it doesn’t necessarily work in a clinical trial.
    2) Clonal heterogeneity- Cancer cells can have populations of slightly different cells in a patient. Over time mutations begin to arise until some of the cells are significantly different. Now a treatment that targeted the cancer might not work on these mutated cells.
    3) Communication with healthy cells- The cancer cells form a complex system where they are able to closely communicate with each other and healthy cells close by. The healthy cells can allow blood vessels to feed the tumour. Cancer cells can also communicate with the immune system to surprise it, making them undetectable.
    4) Cancerous stem cells- These are resistant to chemotherapy and radiation and stay behind long after tumours have been cleared. They seed the growth for new tumours.
    5) Adapt easily- Change their structure to survive under extreme stress
