There are many ways to detect if someone has colon cancer. FOBT or sigmoidoscpopy are just some of the tests that can be done to detect colon cancer. Studies and the actual surveillance of the people that suffer from colon cancer has proven that the earlier this type of cancer is detected, the better results in improvement of life expectancy in colon cancer patients is seen.
For example, three control trials which are randomized, all of them using a specific FOBT test kit have shown serious reductions in death risks from colon cancer. People who were periodically FOBT screening reduced the risk of dying from colon cancer from fifteen percent to almost thirty five percent. Furthermore, two European attempts that randomized colon cancer patients before they gave their agreement to take part in using bennial screening, resulted in almost twenty percent reductions in the mortality rate of those colon cancer patients. Moreover, similar tests have also been made in many other non- European countries using volunteers. Rehydrated test cards were used in this case and the rate of death from colon cancer after eighteen years was almost thirty percent lower in these colon cancer patients who were also advise to undergo FOBT screening every year. Biennial screening also showed to reduce the mortality rate by almost twenty percent. Of course, other trials have also been made in different countries. However, the results were a little bit different, but improvement was shown. In some countries, after these trials, no significant reduction of mortality rate has been shown, but improvement was seen in those colon cancer patients.
Sigmoidoscopy is another screening test in colon cancer cases. Although, there is limited evidence of the efectivness of this colon cancer test right away, better results are expected to be seen in five years time. Studies have been made in colon cancer patients that were given rigid sigmoidoscopy tests and the results were amazing. The risk of dying from colon cancer after using this test was reduced to an amazing sixty percent. Other tests have then been made to verify this result and all the out comings were similar. Furthermore, more studies have also been undergone, but this time using a more flexible instrument and the results were pretty much the same as in the studies that were made using rigid instruments. So, even if results are not seen right away in this colon cancer test, in five years time the improvement is amazing.
Water (H2O) ionizes into hydrogen (H+) and hydroxyl (OH-) ions. When these ions are in equal proportions, the pH is a neutral 7. When there are more H+ ions than OH- ions then the water is said to be "acid". If OH- ions outnumber the H+ ions then the water is said to be "alkaline". The pH scale goes from 0 to 14 and is logarithmic, which means that each step is ten times the previous. In other words, a pH of 4.5 is 10 times more acid than 5.5, 100 times more acid than 6.5 and 1,000 times more acid than 7.5.
When healthy, the pH of blood is 7.4, the pH of spinal fluid is 7.4, and the pH of saliva is 7.4. Thus the pH of saliva parallels the extra cellular fluid...pH test of saliva represents the most consistent and most definitive physical sign of the ionic calcium deficiency syndrome...The pH of the non-deficient and healthy person is in the 7.5 (dark blue) to 7.1 (blue) slightly alkaline range.
The range from 6.5 (blue-green) which is weakly acidic to 4.5 (light yellow) which is strongly acidic represents states from mildly deficient to strongly deficient, respectively.
Most children are dark blue, a pH of 7.5. Over half of adults are green-yellow, a pH of 6.5 or lower, reflecting the calcium deficiency of aging and lifestyle defects. Cancer patients are usually a bright yellow, a pH of 4.5, especially when terminal. Virtually all degenerative diseases, including cancer, heart disease, osteoporosis, arthritis, kidney and gall stones, and tooth decay are associated with excess acidity in the body. While the body does have a homeostatic mechanism which maintains a constant pH 7.4 in the blood, this mechanism works by depositing and withdrawing acid and alkaline minerals from other locations including the bones, soft tissues, body fluids and saliva. Therefore, the pH of these other tissues can fluctuate greatly. The pH of saliva offers us a window through which we can see the overall pH balance in our bodies.
Cancer cannot exist in an alkaline environment. All forms of arthritis are associated with excess acidity. Acid in the body dissolves both teeth and bones. Whatever health situation you are faced with, you can monitor your progress toward a proper acid/alkaline balance by testing your saliva pH.
