Cancer which is one of the top three causes of mortality (death) in developed countries . There are more than one hundred types of cancer which affects various tissues & organs, blood and lymphatics and skin. There is a sense of despair, anger, anxiety when someone is diagnosed with cancer because many people associate cancer with suffering, pain and ultimately death. Modern medicine has made great strides in the war against certain types of cancer like childhood leukemia, skin, prostate and colon cancer but not against others like lung, brain, pancreas and liver cancer.The likelihood of cure increase with early diagnosis and treatment i.e before the cancer has grown to large enough size that press against and cause damage to neighboring tissues and organs. The other concern is that the cancer has already metastasize (spread) to neighboring and distant tissues and organs. General symptoms of cancer include persistent fatigue, unintentional weight loss, prolonged fever or infection, and changes to the skin ( jaundice, darkening of skin, abnormal hair growth, skin itchiness).Cancer is a very difficult disease to treat because it is a disease that involve your cell genes that control cell multiplication. Survival rate (doctors call it remission) varies depending on type and stage of cancer. For example about 49 percent, or about half, of people diagnosed with early-stage lung cancer live for at least five years after diagnosis. The five-year survival rate for people diagnosed with lung cancer that has spread (metastasized) to other areas of the body is 3 percent. Of the survived cases about 90% is due to surgery and balance by chemotherapy or radiotherapy. There are pros and cons using chemotherapy or radiotherapy is readily available on the internet . Both of these treatment as they can cause side effects or worse still cause secondary cancer.The human body can defend itself against bacteria and viruses and even kill cancer cells through intervention of our immune system. Chemotherapy kills cancer cells as well as other useful cells including immune system cells (white blood cells) which are needed to defend our body against diseases and cancer. When someone has cancer he/she needs to strengthen his/her immune system to fight off the cancer. So chemotherapy cannot be considered as a good treatment for cancer and the same applies to radiotherapy. Furthermore doctors cannot detect cancer via X-Ray or MRI when it is smaller than 1 centimeter in size which is equivalent to 1,000 million cancer cells. So if a person has say 10 million cancer cells remaining in his/her body after chemotherapy or radiotherapy, doctors will say that the cancer is in remission as it can’t be detected. But don’t be surprised when a cancer patient suffer a relapse even after a remission.To understand how to treat cancer we need to know why normal cells that make up tissues and organs become cancerous. Normal cells when continuously exposed for years to toxic environment become cancerous in order to survive. Reason being cancer cells have higher survival rate compared to normal cells as cancer cells thrives in anaerobic (lack of oxygen) environment, can generate its own blood vessels to supply nutrients, able to multiply more rapidly, can disguise itself from immune system cells, can dissolve normal cell walls and invade them, and can produce chemicals to destroy white blood (immune system)cells. In fact cancer cells can survive indefinitely in laboratory while normal cells can multiply about 53 times before it stop and cell death occurs. So the secret to treat cancer is to reverse the toxic environment that finally trigger normal cells to become cancerous. Cleansing of the the cell internal toxic environment and improving blood circulation is the key to reverse cancer.
